Multiple Lenovo X230 laptops - "System Event Notification Service" service error / theme problems at boot.

Q: Multiple Lenovo X230 laptops - "System Event Notification Service" service error / theme problems at boot.

Firstly apologies for the length of this one, I've been on it for a while and wanted to share what I could in the hope it might trigger some ideas.


I'm currently receiving an influx support tickets for Windows 7 (x64) devices that are getting the "Windows could not connect to the System Event Notification Service" error when logging on for the first time.

It's predominantly laptops and mainly older Lenovo X230's but there are far more X230 machines without the problem than with it at this time so I'm struggling to tie it down to a specific build, update, application etc. Instances of the issue starting range
from 6 months ago to last week and I have around 200 devices affected (but this is rising).


The issue happens like this for some of the users:

# User boots machine up from being switched off
# Machine boots and gets to logon screen
# User is unable to logon using their fingerprint reader, the green light isn't lit
# They try to logon using username / password, this fails
# "Windows could not connect to the System Event Notification Service" error appears (blue, full screen like the "please wait..." when booting)
# They are then able to try again and the logon is successful
# Error doesn't occur again until they reboot

Many of the users report their machines are also very slow to logon (10-30 minutes) and generally not working as well as they normally do. This is a mix of people in the office and connecting in remotely, various different job roles, locations, installed software
etc - there isn't a pattern I can pinpoint.

I've been through huge number of old posts on this and my colleagues on the service desk have dutifully tried the "netsh winsock reset" fix that seems to helped so many but sadly it's having no impact.

I got hold of of one of the problematic machines and see a slight variation in the problem:
# I boot the machine up from being switched off
# Machine boots and gets to logon screen
# I logon using username / password, this works first time.
# We use Check Point VPN and this prompts for a login during the Windows logon
# When the Check Point window appears it's in a Windows Classic theme rather than Aero
# Subsequent windows and the desktop itself then load in Classic
# "Windows could not connect to the System Event Notification Service" error appears in the system tray as a balloon notification.
# Windows theme is a classic "Unsaved theme" and all Aero themes are greyed out, only basic / high contrast ones can be selected.

If I troubleshoot using the built-in "Appearance and Personalisation" troubleshooter in Control Panel it detects that "Desktop Windows Manager is disabled" - it isn't and it shows as "started" in Services.msc - restarting it
has no effect on my ability to select Aero themes.
Aside from the theme general machine functionality seems unaffected once booted but the delay is causing the users to become frustrated and request new machines. If the machine is rebuilt with the same image, the same software installed and the same updates
applied the issue doesn't occur... or at least hasn't immediately.
I was going to play around with MSConfig and turn things off selectively but decided to use xbootmgr from the Windows Performance Toolkit to see if I could find anything specific happening at boot, "audiodg.exe" seemed incredibly resource hungry.
We have the Realtek audio driver installed on all these machines as part of the build so I disabled the "enhancements" to see if this might help, on the next boot everything was OK, I thought I'd come up with a workaround. The next 10+ boots
all came up with the System Event Notification message. I cried a little inside.
My next step was to disable the sound card in Device Manager - I lost sound but every single reboot after this was fine, no issues with the theme, no System Event Notification Service errors.


I tried updating the driver to the latest version and enabled it again - the issue came back, I also tried uninstalling the driver completely and the machine defaulted to the "High Definition Audio Device" (Standard Microsoft driver 6.1.7601.17514)
and sound worked with no display issues for one boot, it then went back to the problem on subsequent boots.

Unfortunately not having sound isn't an option for a workaround as the users are reliant on it for their day to day work, they also can't enable / disable things themselves as we have device manager locked down.

I've updated Check Point VPN to the latest build, updated graphics drivers, sound drivers, carried out general maintenance on the test machine to ensure it's operating as well it can be, rebuilt the WMI repository (there were multiple WMI errors in the system
logs at boot but these still exist) - so far only disabling the sound in device manager has helped.


Any thoughts / input / therapy would be really appreciated, unfortunately due to the nature of the customer I can't attach detailed logs but I'm more than happy to pull out specifics from them if anyone wants to check anything.

I have a message coming up titled "Failed to connect to a windows service"
and it reads -



?Windows could not connect to the System Event Notification Service service. This problem prevents standard users from logging on to the system. As an administrative user, you can review the
System Event Log for details about why the service didn't respond.?





Also, the task bar and menu <g class="gr_ gr_46 gr-alert gr_gramm gr_inline_cards gr_run_anim Grammar multiReplace" data-gr-id="46" id="46">turns</g> into
a classic style of windows randomly when this is happening. This started happening a couple weeks ago to one device regardless of what network it is connected to.



Does anyone have any ideas on how to fix this? We have already reset the NIC on the laptop to force all settings to DHCP to ensure DNS is being set correctly. Updated DHCP settings
to disable NetBIOS as it is deprecated and should not be used over DNS for resolution. And we have run the <g class="gr_ gr_45 gr-alert gr_spell gr_inline_cards gr_run_anim ContextualSpelling ins-del multiReplace" data-gr-id="45"

My computer recently started having issues........ here is what is going on:
* boot computer
* Windows boot screen displayed ~ 1 minute
* screen goes black. Can move mouse. Drive light constantly on, not blinking. ~ 5 minutes
* log in screen comes up / log in
* Desktop loads ~ 1 minute
> sometimes it loads with regular windows aero theme other times it loads with basic windows classic theme.
* Error message pop up "failed to connect to System event notification service"
* Have to wait for about 5 more minutes before computer is actually usable
* The audio service does not work as well...
from when I press the power button to when I can actually use my computer takes 10 - 15 minutes.

Here is what I have tried so far
*Turning off all start up programs / services
*Tested Memory - passed
*Hard Drive Self Test ---- # 1 - 7 fail / I am guessing that this is the source of the problem, however my computer does still work once everything is finally booted. So I don't know what to do with that information or if that test even matters.
* I have tried looking at the event viewer but every time it says that the event log service is unavailable.
> I try turning on Windows Event Log but that does not change anything
* tried "netsh winsock reset" in command prompt, based on a different thread that I found - it didn't work

This seems to be a common problem, I am now also experiencing the same.
I have Win 7 Home Premium 64. Did chkdsk /r, defragged, tried sfc/scannow scanned for viruses and even tried reseting winsock.
My aero themes are greyed out, when trying to fix it with MS fixit it errors out.
It takes a long time to boot and then says "failed to connect to System event notification service"

One search on google will show this is a major problem, so why does MS not come out with a fix.
This seems to be the biggest frustration with Win 7 compared to XP, lack of support from MS.

Today I booted up my laptop to get this screen - my desktop without an aero theme and the error message on-screen.

Nothing unusual happened last time I used my PC. No installation or updates that I am aware of.

The computer cannot shut down properly now either, it just hangs after the desktop icons are gone. I am forced to hard shutdown.

Please Help !

My HP running Vista Home Basic suddenly gave me the following error message on startup: "Failed to connect to a Windows service: Could not connect to System Event Notification Service".
Among other things, this prevents me from connecting to my internet network, so I can't get on-line.
Rebooting did not help.

Following the google search I used an elevated command prompt (click Start, click All Programs, click Accessories, right-click Command Prompt, and then click Run as administrator) and typing "NETSH WINSOCK RESET ", then press the Enter key, and then restart the computer.

I still cannot access my internet network, instead of not connection now I get the message "unidentified network" and I still cannot go online although there I have some Mbs

It sais (I do not understand this text )
"What netsh winsock reset command does are it resets Winsock Catalog to a clean state or default configuration. It removes all Winsock LSP (Layered Service Providers) previously installed, including the potential malfunctioned LSP that causes loss of network packets transmission failure. So all previously-installed LSPs must be reinstalled. This command does not affect Winsock Name Space Provider entries."

Please help me with the next step in order to be able to go online from my computer.
Thank you!

More: I can't access the Windows Help & Support pages. And I'm told to "see System Events log" for details, but when I try, it says "Event Log Service is unavailable." When I try System Restore, it says "back-up hasn't been set up." (Aren't restore points set automatically?)

Hey all,
I am having an issue with a user connected to our local domain. Whenever they try to log in, it keeps displaying "Windows could not connect to the System Event Notification Service service." I have tried multiple ways of addressing it and have
had no luck with a fix for this. I have tried:

Using 'netsh winsock reset'Uninstall and reinstall network adapter driversClean booting and trying to isolate the issue (did not find anything)
Deleting the font cache Tinkering with the service settings Disabling anti-virus and restarting
System Restore
None of these are fixing the issue for my particular system. It always comes back. The hardest part about troubleshooting this issue is how sporadic it is. It happens every other time the user logs in.

The only other fix I have not tried the hotfix they released for this yet. I don't want to install this until I have exhausted all of my options as this could create more problems.
We have 50+ other computers running Windows 7 on this domain with absolutely 0 issues. Any help with this would be greatly appreciated!

I have been getting the following errors when I try to log into my account.

The system event notification service service failed the logon an attempt was made to reference a token that does not exist

I created a built-in-administrator and I am able to get into safe mode though not able to run many programs on it such as control panel and start up repair. I looked at my registry and both of my accounts look fine neither of them had a .bak on the end and so I'm not sure how to fix this if my only option is to delete my user account. I've already done a system restore to a couple days before this happened but, I'm still locked out of everything.

Is there anything else I can do that might help?

A:The system event notification service service failed logon ... token does not exist

Google led me to this post as I was researching the problem myself. I encountered the same issue. In this case on a vista32 ultimate box (although I do own an x64 box in case somebody thinks I'm blasphemous posting here ).

I haven't completely fixed the issue yet but I've gotten a bit further so in hopes of helping the next person here are the steps I've taken.

I was able to log in successfully in safe mode (hit F8 while starting up, select safe mode). Once there I went to command prompt (click the start button, type "cmd" [without the quotes] in the search bar and hit enter. From command prompt type services.msc to launch the services control panel. Find the System Event Notification Service, right click, select properties, change it from automatic startup to disabled, apply the change and "OK" out of the dialog box. You can now restart the computer and log in normally.

This isn't really a fix, it's a temporary work-around. SENS is needed for COM+ to respond to things like login and startup events. I've also noticed that my system is very slow right now. My next step is to find a way to generate a new token for SENS and then hopefully I'll be back at 100%. I currently have Dell researching that for me (this happens to be a Dell laptop). If I get a solution short of a reinstall to that one I'll post it too.

Hope this is helpful for someone. Good luck.

I logged on to my computer as an administrator and my desktop didnt display for about 4 minutes. There was only a black screen with the white mouse arrow on it. When the desktop had loaded a Windows notification
bubble popped up saying:

"Windows could not connect to the System Event Notification

I don't believe that I have installed any software etc. recently that could have caused this problem to occur. It just randomly happened one day. In sync with this error I am unable to connect to the internet using my 3 mobile modem and my laptop isn't recognising any wireless signals bringing up the message:

I have a problem with the system event notification service. Whenever I use my Asus V1JP-AK028E with Vista Business to access any Standard User account, it comes up with an error message - "Login failed, System Event Notification Service service could not start. Contact a system administrator".

When using password login to a Maintenance account I created, it comes up with the same error. This is an administrator account. When using fingerprint login to this account, it works, but the error message comes up in a popup when I first see my desktop, and then I'm logged off.

Hi guys,

Everytime I start my computer, it starts in the Windows Classic theme, with Aero disabled, and unable to be turned back on.
In addition to this there is a pop-up that says

The Aero issue can be temporarily resolved by switching user to another one, then logging out of the other user, then back into the main account.

I'm unsure if this is the correct thing to do - but here's how to clear the repository (originally found at this link: Repairing and re-registering the WMI ):

Open an elevated (run as Administrator) Command Prompt and type
"net stop winmgmt" (without quotes) and press Enter.
Leave this window open as you'll reuse it again later.

Open Windows Explorer, navigate to %windir%\System32\Wbem\Repository (%windir% is usually C:\Windows ). Rename the Repository folder to Repository_OLD
Then close Windows Explorer

Go back to the elevated Command Prompt and type:
"net start winmgmt" (without the quotes) and press Enter

Then type "exit" (without the quotes) and press Enter
Then close the elevated Command Prompt window and see if that fixed things.

Howdy y'all,
The message continues: "It may be a more recent revision than the service is aware of."
The PC is XP Pro SP3 with all patches. Security Essentials is still running and signatures are current. The system won't boot to XP. The message in the title field is displayed in a dialog. After clicking OK, the system iterates a reboot cycle.
Tried to boot using Last Known Good Configuration, but no progress.
Research shows that there was malware that could cause this problem, but not in the last few years.
What might have caused this and how to fix this efficiently? I read an article that recommended restoring the registry files from an earlier version. We'll try this after removing the disk and connecting it to another PC:
http://community.spiceworks.com/how_to/214-perform-a-system-restore-manually-when-windows-is-not-bootable
Thanks kindly.

A:lsass.exe: System Error. "Indicates a revision number encountered or specified is not one known to the service."

Issue is resolved. Firstly, we scanned the PC with Windows Defender Offline. No malware was detected. The lsass.exe error occurs when the Security hive of the XP registry is corrupted. The Security hive of the registry consists of a key and files. The
registry key is HKEY_LOCAL_MACHINE\Security, and the files are Security, Security.log, Security.sav.

More information about the Windows registry is in this MSDN article:
https://msdn.microsoft.com/en-us/library/windows/desktop/ms724877(v=vs.85).aspx

To restore the Security hive, we booted the PC to the Recovery Console that was already installed on the local disk. The password for the Administrator account was prompted for and entered.

The Recovery Console command line showed that the current folder was C:\Windows.

CHDIR system32\config
REN security security.old
COPY c:\windows\repair\security
EXIT (to restart Windows XP Pro)

The system rebooted normally.

I ran a registry cleaner which didn't work and ran memtest this morning and it showed that my memory was fine. The BSODs tend to occur more often when I am playing a game or running some program that uses a bit more memory but it also happens when I am just on the internet. On the other hand, last night I did nothing but surf YouTube for 3 hours and didn't get a BSOD at all.

I reinstalled Symantec Endpoint Protection from the computer and it now appears to be working. But I am skeptical and intend to keep a close eye. If anyone has any experience with this feel free to still chime in.

My HP with Windows 7 suddenly gives me the following error message on startup: "Failed to connect to a Windows service: Could not connect to System Event Notification Service." Among other things, this prevents me from connecting to my wireless network, so I can't get on-line. . Rebooting doesn't help. And the problem occurs regardless of whether I sign on as administrator or as general user.

More: I can't access the Windows Help & Support pages. And I'm told to "see System Events log" for details, but when I try, it says "Event Log Service is unavailable."

I have tried netsh winsock reset but it doesnt help

Please help!
 

A:Could not connect to System Event Notification Service

Same problem exactly. Tried disabling Kaspersky (internet security 2011) and restarting, but no change. System's been buggy all along, so this just seems like the natural progression of things... But no network connection is pretty hard to work around!

For me this started after i interrupted a shut down by closing the laptop - which puts it into hibernation mid-shut down... Which may or may not be a contributing factor.

Every time I start my computer and log in, an error message pops up when I get to my desktop:Failed to connect to a windows service.Windows could not connect to the System Event Notification Service service. This problem prevents limited users from logging on to the system. As an administrative user, you can review the System Event Log for details about why the service didn't respond.How can I fix this?

Type services.msc in the start search box. click on the icon, Windows services will open.Scroll down to System Event Notification, right click and choose properties. In the dropdown box, set it to Automatic and start the service.

I have tried each and every one of the solutions on the forums and over here. All my drivers are up to date (double checked), I rolled back and uninstalled all updates, Did sfc /scannow three times and they passed without any integrity violations. I've tried netsh winsock reset as well. The aero is gone, greyed out plus I can't select any other theme and whenever I start up the computer it displays the message "Could not connect to a Windows service".

This started happening about 2 months ago when my laptop ran out of battery in hibernate mode. It didn't resume so I had to press the power button again and then it took about 8 minutes to boot with nothing but a black screen and the mouse there. The audio service isn't running every time I boot up (I have to right click and run troubleshooter to start it).

Does anyone have ANY idea what might be causing this? How do I fix it? I've uninstalled all the software that I installed before the error occured as well.

I'm using Windows 7 Ultimate on a Sony Vaio VGN-NW25GF. Intel Duo core T6600 and the ATI Radeon HD Graphics 4570 card.

A:Could not connect to the System Event Notification Service

I would try a Repair Install as a last resort before running Vaio Factory Recovery from its partition - make the backup disks first as a secondary backup method.

However most tech enthusiasts want the better performance of a Clean Reinstall - Factory OEM Windows 7 using the Product Key on COA sticker. Everything you need is in the tutorial.

A:*RESOLVED* Media Center "Tuner Not Found" error, "Receiver service has stopped"

Okay, I resolved the first two issues, Tuner error and ehrecvr error.It had to do with multiple Admin user accounts on my computer. My computer was originally set up with a user Robert Baker with full privileges as administrator. I then also set up a MediaCenter account with full privilidges. For whatever reason the MediaCenter account has access to EVERY action on the computer except starting the ehrecvr service.1.  First set Media Center Service Launcher to log on at NT Authority    Services > Right-Click Windows Media Center Service Launcher > Properties > Log On tab > Log On As 'This account: ' > Type " NT AUTHORITY/LocalService " > Click Apply > General tab > Start service.2. I then set the Media Center Scheduler Service AND Media Center Receiver Service to log on as my other admin account. Same as above but with other account credentials and started the services.3. Reboot and no ehrecvr errors. Since this was a good sign I tried WMC and was able to set up my TV fine.I STILL, however, get the "Upgrade in progress" message when I open Media Center. Anyone know how to fix that? I've run setup again and can't get rid of it.

A:Failed to connect to System Event Notification Service

Usually it's a driver or COM component that's causing this. What does your Application and System event log show you as warnings or errors?

Hi i have a couple of users on our network who are receiving the following error on startup "Windows could not connect to the system event notification service service. Please contact your system administrator" When this error is receive i always notice the startup time take an extra 2-4 minutes before it even gets to the login screen. Once logged in the users gets the error after a minute it can automatically go back to the login screen or if you press OK it also goes back. On second attempt it will log in with no errors.

So far form everything i have researched and tried nothing seem to fix the issue. This is what i have checked and done. Oh and these 3 machines that are getting this error are on Windows 7. We get no event viewer message or error about the issue.

-Made sure the services are running and started and set to automatic - mainly the Windows Event log, COM+ etc everything is started as it should be
-Rebuild WMI repository (which did fix issue for a 3 days then returned)
-Netsh catalogue reset and winsock reset
-Tried Hotfix - KB2590550
-Made sure network drivers were updated and the latest
-SFC /scannow
-HDD healthcheck done - is OK


Anything anyone else can suggest would be great or if someone has been able to fix this issue permanantly please let me know???


Thanks

So recently I had hardware issues, and through warranty I had several replacements done. Mobo, Video cards, ram sticks, and the power supply.

After all that was fixed and replaced my computer seemed to have ran fine for a few days, and it still technically is except for this problem.

The problem is when I log in into windows normally it takes a while for Windows to boot up. I get a "Please wait" screen, then after a long 4 minute log in once inside windows I get the"Windows could not connect to the system event notification service", and the toolbar is grey all old school windows like.

The problem is the exact same as the issues found here except I am using Windows 7 64 bit.

In services the service is called System event notification, it says that the service is running fine. Even when i try to restart it, it makes no difference at all.

As for in event viewer. Im not to sure what to look for in there.

Ive looked at several familiar threads, I did the sfc /scannow twice, i did a windows start up repair, I disabled all non-windows services, and even just tried restarting the service in services.

I'm not really sure what to do next. I'm tempted to just to do a clean install. However I am cautious on doing so, in case its some kind of hardware problem...

This is the message i am getting on startup:

"Failed to connect to a windows service.
Windows could not connect to the System Event Notification Service service. This problem prevents limited users from logging on to the system. As an administrative user, you can review the System Event Log for details about why the service didn't respond."

The message comes with a very slow start up.

The computer doesn't seem to recognize any of the wireless networks either, so i currently can't connect to the internet either. So i am using a different computer right now.

I have a desktop computer running Windows 7 Home Premium 64-bit SP1. Yesterday, Vidcoder (a front end for Handbrake) attempted to update to version 2.44, but Norton blocked the update with a security warning (vidcodercommon.dll, threat WS.Reputation.1). Because I found a reference to Vidcoder and AutoComplete Pro, I followed the advice at https://malwaretips.com/blogs/remove-autocomplete-pro/ - and ran AdwCleaner, Malwarebytes Anti-Malware Free, and HitmanPro.

Now, my computer boots slowly to an account with Admin privileges, but shows a bubble message, "Failed to connect to a windows service. Windows could not connect to the System Event Notification Service service. This problem prevents limited users from logging on to the system. As an administrative user, you can review the System Event Log for details about why the service didn't respond." The computer has no internet access, and says, "Not connected. No connections are available." A Norton Internet Security scan is clean (but limited because there is no internet access).

Google reveals multiple posts about this problem, with multiple suggested fixes. For fear of making the problem worse, I have not tried any of the fixes, and I have not done a system restore. I would greatly apreciate some help. Thank you.

Sorry, I know that a thread already exist with the Title "Failure to connect to System Event Notification service".
But having tried everything in the thread and without any success, I decided that it was important to post the solution that fixed the problem in my case.
I had the problem with Windows 7.
After many hours trying anything I found on the web, I was being reinstalling my BitDefender AntiVirus.
(Because I uninstalled is to allow me to perform a System Restore to a date before the problem occured)
Anyway my System Restore did not work.
Then, while I was reinstalling BitDefender, the problem was still there...
But during the re-installation of BitDefender, the installer told me that I should uninstall MalwareBytes because it could cause conflicts. So I did.
Then after rebooting, and the problem was gone at the next login and then BitDefender finalised it's installation.
So, I strongly believe that it was solved by uninstalling MalwareBytes.
Now, after 4 reboots, I don't see the problem anymore.

since about 3 months ago, my computer has been experiencing multiple BSOD's per day. upon looking in the event viewer, ever single time and event with something to do with a "VSS service" is the last thing before the crash. i find this strange, as looking into this, vss is a backup program for xp and server 2000. i have no idea why this is on my system, what it does, or why i need it. after trying to use some debugging tools, it seems that i cannot access the .dmp files on my own computer, logged in as an administrator, with full privileges, with all file security options in my anti-virus off. my system is a x32 vista business. the crahses occur almost at random, doing anything from playing a game, using Firefox, typing a notepad file, or just leaving the thing on and not doing anything for more than 10 minutes. the system will still crash at the log in screen, leaving me to believe that this is not an overheating issue. i have tried to disable all programs with mscofig, but i still get a crash. i have even had crashes in sleep mode, as well as in the process of a normal shutdown. i have no new updates in windows update, and have installed all of the new drivers for every device i can find them for. any and all help would greatly be appreciated.

I dug around quite a bit... I really hope this hasn't already been a thread...

"Failed to connect to a windows service.
Windows could not connect to the System Event Notification Service service. This problem prevents limited users from logging on to the system. As an administrative user, you can review the System Event Log for details about why the service didn't respond."
​This message comes with slow start up and shut downs that occasionally freeze. Another strange symptom is that sometimes (about every other time I boot up the computer) it loses the shiny-black Vista theme. Not so much a concern of aesthetic and more a note of wonkiness.

The laptop was sluggish recently and I was doing some cleaning: defrags, registry cleaning, virus/spyware scans, etc. I... have a theory my sweep with CCleaner may have done something it really shouldn't have. I'm unsure what to do about this if it is true though, because although I didn't delete them, all my restore points are gone. I also recently changed the virtual memory size, if that is relevant.

Also uncertain of relevancy, but the worst of it (Service message) began while I was toying around between Pidgin and Trillian. Trillian crashed... something. There are so many event logs now that I'm not able to figure out what it was

Gringo_Pr,
 
I am wondering if my system may have gotten a virus.  On boot and attempting to log in I frequently get a message "Windows could not connect to the System Event Notification Service service."  When it does this I get a message that it can't access my profile too.  It then uses the default.
 
I have run Microsoft Security Essentials, Malware Bytes and Spybot.  They don't seem to find anything.  But I am not convinced.  In browsing my event viewer - system I see system services that crash and restart.  So, either my machine has a virus or it is starting to fail. :-( 
 
Thanks in advance for taking on another challenge.

We've been having a LOT of difficulties with Vista on our laptops recently.  The bootup process goes relatively fast until it gets to the "please wait" screen just before CTRL-ALT-DEL would normally appear.   The laptops can sit here for 10 minutes or 10 hours.  No rhyme or reason.  Nothing in the event log says anything about what it is trying to do.  Everything seems normal except this LONG wait at "Please Wait..."After some experimenting, I determined that if I disable the "Network Location Awareness" service, everything works fine.   Better than fine actually... everything is faster than ever.  Boot up takes 45 seconds from power on to the CTRL-ALT-DEL screen.My question is, why all of a sudden is this an issue?  Why would NLA cause huge hangups and delays on boot?  By disabling it, it seems to be fixed, if not better than before.  If I leave this disabled, is it going to break anything else?   Minded, we are a school district.  We have a local network.  No internet acess unless through a proxy.  Relatively simple network setup.   2008 servers.  1 domain controller.Ideas?
