Windows Event Log Service Crash

Q: Windows Event Log Service Crash


I have an Active Directory Domain with Win2008R2 DCs and Win7 clients.
From about 2 months ago some of my clients complain about time of the system which is behind the DC time.
When I nailed the problem I noticed permissions of folder
"C:\Windows\System32\LogFiles\wmi\RtBackup" folder is the key to the problem. Group 'System' should have access to this folder and

based on some unknown reasons this permission is deleted.
Because of this permission problem, 'Windows Event Log' service is stopped either.
When I correct the permission and reboot the clients, every thing works fine.

Do you know what is causing this problem? What is changing permissions of RtBackup folder?

Preferred Solution: Windows Event Log Service Crash

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)


HI I have a functioning ATA-installation, with a single remote gateway monitoring 3 production domain controllers. I configured the gateway server as an event collector and now have the gateway server pulling 4776 events to the Forwarded Events log on
the gateway server. Now when I try to enable the gateway to monitor forwarded events, the gateway crashes pretty much right away ("the service stopped unexpectedly") Am I missing something?

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 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
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."

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:

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"

Hi all,

i tried loading the eventvwr.msc file from system32 folder directly as well as from the administrator tools, but i get:

"event log service is unavailable. verify that the service is running."

so i try to start the event log service, from the services.msc program;
whenever i try to start windows event log from services i get the message:

"Windows could not start the windows event log service on local computer.
Error 3: The system cannot find the path specified."

how can i specify the path?

any help would be appreciated please---thanks

A:HELP need to solve this problem asap - Unable to start event viewer/event log service

Fire up regedit and find this key:


With "Eventlog" highlighted on the left pane, you should be able to see a value called "ImagePath" on the right. ImagePath should be equal to this:

%SystemRoot%\System32\svchost.exe -k LocalServiceNetworkRestricted

If you can't see "ImagePath" in that location, or if it's not set to the text above, that's almost certainly your problem. If you're in the habit of using "registry cleaners", that might be the cause.

Hello Everybody,
We have a requirement in our project to audit all security relevant events on the system, including the start/stop of auditing functions. The problem is that windows is not registering the start of event log service when you manually stop/start the service.
There only an audit event on the system log, but linked to the system startup and not under security category when you do the start/stop manually. Is this a windows bug or a matter of configuration?
Best regards,

I built this system about three months ago, and until recently, it worked great. A couple weeks ago, however, it started crashing on a roughly daily basis. There seems to be some connection to load, in that it didn't crash yesterday when I was just typing and doing research. That said, the circumstances under which it does crash aren't very burdensome, since merely streaming a video is enough to put it at risk (it does not reliably crash under any circumstance). When it does crash, both of my monitors go monochrome and my speakers start emitting that electronic crashing noise, like what you get when you bluescreen. As far as I can tell, this will go on indefinitely until I manually turn off the computer. The Event Viewer shows no critical errors except for when I turn off the power.

Someone on another forum suggested that my RAM timings might be wrong. I checked, and in doing so discovered that my motherboard wasn't detecting one RAM module (the timings were correct). I assumed that I had faulty modules and bought some new RAM of a different brand to replace it, which didn't fix the problem. The RAM timings should be correct, as I loaded an XMP profile. At this point, I'm at a loss and would really appreciate any help.

Hi Bob,
This issue can be caused due to the incorrect permission settings for the administrators group.
I would like to suggest you perform the following steps to troubleshoot the issue.
1. In the "Start" menu, locate "Command Prompt". Right-click and choose "Run as Administrator". If you are prompted for an administrator password or confirmation, type the password or provide confirmation.
2. Type the following commands, then press "Enter" to execute them one by one. Please note the space before the command and its parameter.

3.   Restart the computer to check the issue.

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???

Okay, I am a pretty technical user, and I am really struggling with this issue, and I wasn't 100% sure which section to post this in. I used to share videos over my network with multiple xboxs and a ps3. I recently installed Norton Internet Security on my system, and after doing so, I was not able to stream videos anymore. I tried changing firewall settings, and permissions and such, but could not get it to work, so I uninstalled NIS from my system. After doing so, the Windows 7 firewall service will not start. If i look at the event log, it gives me Event ID 7024 : The Windows Firewall service terminated with service-specific error Access is denied.. I have run the norton removal tool, and this has not fixed the problem.

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...

Anyway do any of you have any recommendations or other possible solutions I havent tried ... Read more

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.

Hey everyone,
I've been having this issue where my PC locks up, doesn't reboot without a hard shutdown, no BSOD. For a while I didn't look into it because my machine would crash during the night, so I would just try and turn my monitors on in the morning, and nothing would happen, and my keyboard wouldn't light up when pressing keys so I'd just reboot. The past few days, it has been crashing much more frequently. I figure since there's no BSOD and the machine doesn't reboot, it might be a GPU issue even though it's around a year old, if that.
I'm in IT, but I'm not sure how to find the cause of crashes when there's no event log or if it's specific to a piece of hardware, so if you have a methodology or tools you commonly use, I'd love to know more.
The only thing I've tried so far has been chkdsk and some tools to check HD integrity. Both came back clean

TL;DR: I got a scam call from Dell's "concierge" number (1-877-790-3355). The caller had several pieces of personal information, including my name and service tag, and details of my recent system servicing. He said Dell had been notified that my computer was downloading malware, and got me to open the Windows Event Viewer, showing me the errors in my administrative events folder. He told me to delete these, which was when my suspicion finally got the better of me and I hung up. He called back, first on the same number, then on another one that appeared on caller ID as "Global Pacemind" (Everett, WA, USA - 1-425-609-3257). I told him that I didn't have time right now (I wasn't yet 100% sure this was a scam, but didn't like where it was going), and he said that he'd call back.

Every so often one of our Windows 7 clients which is not normally having any delay at logon will take a very long time to login. This may be 10 or 20 minutes or up to an hour in some cases.
Typically the event log will contain entries like
The winlogon notification subscriber <Profiles> took 572 second(s) to handle the notification event (Logon).
There is no further information available from Event Log Online Help, nor any additional detail as to why the logon event was so slow. During the delay the user will just see "Waiting for the User Profile Service" on their screen.
We first started seeing this problem with Windows Vista and if anything the situation has not improved since then. It has never happened with any of our Windows XP users.
We are currently planning a migration of computers to Windows 7 but stuff like this which has not been resolved in Windows over a 2 year period will stall that migration. The least improvement is to increase the event notification to give a lot more
information on why the user profile processing has stalled.

A:Windows 7 very slow logon, Waiting for the User Profile Service, winlogon event 6006

When did the issue begin to occur? Did it occur after installing certain application or applying certain policy?
To troubleshoot the issue, please perform the following step.
1. Restart the machine in Safe Mode with Networking to check whether the system can login quicker.
2. Type “gpedit.msc” in Search box and press Enter. Navigate to the following location:

I recently formatted my Acer 5542G laptop, and changed its OS from Windows 7 x64 Professional to Ultimate. I did this because my laptop started running super slow when it booted and after. I installed the Ultimate and I had no problems so far. Windows did the updates as usual, but when it started installing Service Pack 1, that's where I started having some problems with it. It downloads the SP1, and when I restart the PC, it starts to configure the update, this will start working normal and it freezes somewhere at 15% for 5 minutes then it continues, and suddenly while configurating the PC stops, and it reboots. It shows the Acer booting screen, then it asks me If I want a system repair, or a Normal Start-up, when I choose the second option, it starts the Windows 7 booting animation, as soon as the 4 lights appear and get a little bit together, the computer freezes, it quickly shows me Blue Screen of Death(Which I can't read because I have automatically reboot machine after start-up failure, If it helps I can check for it) and it restarts the computer. I have fixed it by restoring. I did this installation like 5 times not and it has failed every single time. I even tried downloading and installing SP1 manually but it still fails. Can I do something about it or just switch back to Windows 7 Professional?

Thank you for reading, if you are able to help me, I would be very thankful. Have a good day

A:Windows 7 SP1 (Service Pack 1) won,t install properly and crash

There is no difference between Professional and Ultimate in terms of performance - they are exactly the same OS. So use the Professional license you already own for the life of that machine to do a Clean Reinstall - Factory OEM Windows 7.

Use the official installation media with SP1 provided in Steps 1 and 2 and not a pre-SP1 installer. Follow the steps and stick with the tools and methods and you will have a perfect install to the exact extent you do.

Hi all and thnaks for taking time to look at this thread.

Yesterday I installed service pack 2 on my XP Home machine. Halfway through the installation I got the following message:

Migrate.exe - Entry point can not be found in (then here was the name of a dll that I have sadly forgotten).

I pressed cancel, this was the only option and then the message reappared. I did this many times until I finally pressed reset on my PC.

My PC then restared but freezes in the WIndows XP screen where that blue status bar is to show its loading. When I try safe mode or last know good configiration then it also freezes.

Im pretty sure that I will have to reinstall everything but is there any way of getting my data from the PC?

1. I noticed my Windows Diagnostic Service is OFF, but I can't turn it ON, the "choice" is greyed out. Can anyone help me on how to turn it back on? 
2. Not sure if it is related OR separated problem, i encounted a mini dump/ crash, but not the "blue screen of death, rather, the computer will simply turn off by itself. From the control panel/ problem list, i see 2 issues: Services Diagnostics Host Hung on starting, & Services internet sharing hang on starting.....
I ran a Windows Memory Diagnostics Tool test, luckily, it states NO memory errors were detected. 
I ran the famous Malwarebytes and SuperAntiSpywares, which both are highly recommended by this forum/websites, turns out to be OK ( i ran in safe mode) 
Can anyone help me on how to fix my problems. Thank you.
Here are the specs of my compuer:
Sony AR-770 Vista Ultimate SP2/  32 bits based computer/ 4 GB RAM Memory/ 300 GB Solid State Drive HD/ 

A:Windows Diagnostic Service is OFF & mini dump crash related!?

Thank you in advance !

I have 1 laptop Satellite L750, and windows service audio crash randomly.
I have two windows 7 install, reinstall all sound driver repeatedly, but same problems.

Any ideas?


A:Satellite L750 - Windows 7 audio service crash randomly

For me this issue looks more like Microsoft Windows system issue (probably sound driver) and therefore I recommend you to check the MS support community for possible solutions.

I found this interesting post in the MS forum:
[Windows Audio Related Crashes|http://answers.microsoft.com/en-us/windows/forum/windows_vista-pictures/windows-audio-related-crashes/49a3634b-6dfe-4208-9c22-c8be6242b2ac]

According to the 2nd post, the sound driver reinstallation should fix such issues.
In case this workaround would not fix the sound audio problems, I recommend roll back the system to the early point before this issue started to occur.

In worst case you would need to recover the notebook using recovery disk but I guess you should try the workarounds recommended by MS

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 ... Read more

Hello, I am new here. I have been having problems with Windows 7 explorer constantly crashing and restarting whenever I right-click on or open any files and folders, search in the Start Menu search box, opening My Computer, Control Panel, etc. In essence, it is limiting most of the interface. I was able to pinpoint the problem using Safe Mode and msconfig to the 'Power' service (C:\windows\system32\svchost.exe ?k DcomLaunch). And once I disabled the 'Power' service, everything seems to be fixed.

However, disabling the 'Power' service will disable audio service for the system. To fix the audio service, I tried changing the Power management, reverting back to previous restore points, updating the audio device drivers, trying to enable the Windows services in services.msc for 'Remote Procedure Call (RPC)', 'Plug and Play', 'Multimedia Class Scheduler', 'Windows Audio Endpoint Builder' and 'Windows Audio' to activate sound again, but 'Window Audio' depends on 'Windows Audio Endpoint Builder', but 'Windows Audio Endpoint Builder' seems to depends on the 'Power' service. And I can?t activate the ?Power? service again without crashing Windows explorer. How do I go about fixing this issue? Can I replace the ?Power? service files? Or update them? And help is much appreciated. Thanks in advance!

Welcome to Seven Forums Shintou. Based on what you have discovered so far, a repair install may be your best option. However, it is worth your while to try the System File Checker before trying a repair install.

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

A:Windows failed to conect to " system event notification service"

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.

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!

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.


Any ideas?

I doubt its malware but will run scans soon to double check.

Ever since installing IE7, I get periodic crashes in IE, and in the application log it's always:

Event ID: 1000

Faulting application iexplore.exe, version 7.0.5730.11, faulting module ntdll.dll, version 5.1.2600.2180, fault address 0x00031c6b.

The fault address changes, and once I saw one for module mshtmled.dll, but it's usually ntdll.dll that is flagged.

Anyone have any words of wisdom on this issue?

My newly acquired Compaq Presario 5500US has had various problems and have a list of error notifications. but I have not been able to solve its random crashes, of which the latest ones are not listed in the event viewer.

Long time ago, when i upgrade my vista home premium to ultimate, i forgot to back up my VAIO files, and now they are all gone, like Fn key and S1 key doesnt work anymore,does anyone know how to fix that ?



A:Vaio event Service gone.

The VAIO factory installed apps would not have carried over without an in-place upgrade.

Otherwise they need to be reinstalled. Check the Support Downloads page for your model on Sony's Website, any disks that came with the Sony, or call Sony Tech support to inquire.

If you cannot do without them, then see if you can still activate the Vista recovery partition if it wasn't deleted/formatted, perhaps by tapping the F-key given for recovery on first boot screen.

Sony can also provide you with the Vista recovery disks, so that you can restore to factory condition, remove the bloatware you don't want, clean it up to remove corruption making sure uninstalled software is removed in Software keys of second and third registry hives, and using these tips: http://www.wikihow.com/Remove-Crapwa...ndows-Computer especially CCleaner and defragging.

Now you can do an in-place Win7 Upgrade that will carry over your preferred apps while leaving out the Sony bloatware.
