{Solved} - DHCP active leases not being updated when dialing into network via RAS server

Q: {Solved} - DHCP active leases not being updated when dialing into network via RAS server

When logging onto the company network via a RAS server, the DHCP active leases is not being updated with the IP address assigned to me. This is the case both when the RAS server is configured to give an IP address from a fixed pool, or when configured to obtain IP address from DHCP. As a result, I'm experiencing problems if an existing lan device has an IP address assigned and the dialed in device grabs that address. Whats going on ?

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.)

A: {Solved} - DHCP active leases not being updated when dialing into network via RAS server

Greetings

There should be a clear distinction between the IP adresses available for the network, and those available for the Dial up users. Do not make them part of the same IP group.

The reason is that Dial-up IP addresses should have a lease time of a few hours, and the LAN lease time should be that of a few days. This is obviously not compatible, so they need to be seperate.

Hope this helps

I'm running a simple network at home with a Linksys BEFSR41 router. I have two computers hooked up wired and a wireless router acting like an access point that I use for my laptop occasionally. Until this weekend I've been having no problems but I shut down the computers due to weather and now one of them is not able to communicate with any others on the network. The problem computer will get an address supplied to it by the router (DHCP server) but once it has it I cannot get any other connectivity. Of course this is hindering internet access on this computer. I can ping the loopback and assigned IP addresses w/o problems but when I ping the default gateway (router) and/or the other computer I get "Request timed out." I initially thought it was the NIC so I bought another one but still get the same issue. I've moved the cards to different PCI slots but no luck. I tested the cable running from the computer and the router but found no problems. I even tried resetting the TCP/IP stack but still didn't work. The computer in question is running WinXP SP2 with the original NIC being a Linksys LNE100TX and the new one being a D-Link DFE-530TX+.

Any clues on this? If more info is needed let me know--it's been a while since I've posted. Thanks in advance.

My WinXP Home PC won't connect properly (limited connectivity/no internet) via ethernet cable to my router (Belkin N150).

Ipconfig /all shows the IP address as 169.254.117.71 but this is determined by an entry in the registry at HLM\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\{39A...} > 'DhcpIPAddress' - REG_SZ - 169.254.117.71. Also listed at 'IPAutoconfigurationAddress'. My laptop connects fine plugged into the same port getting it's IP automatically (192.168.2.2) and getting internet fine.

After much searching I can't figure out what's wrong.

I've tried adding a DWORD entry 'IPAutoconfigurationEnabled' = 0, also tried deleting the 2 values.
Tried setting the IP manually to 192.168.2.6 - limited connectivity goes away but I get no internet connection from the router nor file sharing.

Any help please?

Hello Everyone,

We our setting up a Training Company to assist unemployed IT people in the Silicon Valley area of California. Our group is very small and having a hard time even getting our network here started. Here is the problem: We have Windows 2003 Server Enterprise 180-day usage disc (from a book we bought to learn). We have 5 static IP addresses leased from DSL carrier. They are for example: 65.123.141.10 thru 65.123.141.14 with a gateway of 65.123.141.9 [these are only IP numbers used for example to prevent hacking] my subnet mask is 255.255.255.248 We tried and tried for 2 weeks now and still can not get the complete network to work. We need: Step1.) The server to be secure with a firewall (but willing to forgo that and add later) Step2.) the server to issue Ip addresses from a pool of 192.168.0.10 thru 12 to 3 workstations running XP(we decided to make the server 192.168.0.5, subnet mask is 255.255.255.0 and gateway 192.168.0.1 Step3.) Have access to the internet on all workstations and the server too. All we have succeeded to do is get the dhcp to issue out addressses to the workstations and even that i think we got lucky. We think the problem is somewhere you need to tell the (maybe iprouting?) setup that the Public ip address is the 65.123.141.10 and gateway, subnet info and to route to the server PRIVATE ip address 192.168.0.5

Nothing really comes to mind, but if you're using Window's Wireless Zero Configuration maybe you need to reconfigure your wireless connection; especially if your network is protected with encryption.

I use the utilities from my wireless cards' manufacturers to connect to my WPA protectecd network and had no trouble today after the same reboot (two notebooks). Well, same reboot if you're talking about the critical update released yesterday.

Hi folks,

As I've said in the title, I'm looking to make a network with two routers but only having DHCP enabled on the secondary router.

Before I go any further I must ask: I have an Arris GT840A (sigh) as the primary ISP required modem. I'm currently connecting via wifi and sometimes have pings to the router coming back in the 1 - 20ms range for extended periods and it's decent. Other times I get a huge range of different ping times, often in the 300ms - 6,000ms range and sometimes even dropped.

Is disabling the DHCP server on the modem and relegating all local networking duties to my WRT54GV2 likely to alleviate this problem, or does this simply boil down to I'm screwed because I have to use this Arris modem?

Moving on with the primary question, here is my current setup:

Router 1: Arris GT840A
WAN IP: Dynamic / ISP assigned
LAN IP: 192.168.0.1
DHCP: Enabled
192.168.0.2 - 50

Router 2: WRT54GV2 (Connected to router 1 via WAN port)
WAN IP: 192.168.0.51
LAN IP: 192.168.1.1
DHCP: Enabled
192.168.1.2 - 50

With my current setup I have been able to ping both router 1 and 2 via wifi, but I have not been able to ping or connect to the internet at large. I have read a couple of different how-to's and other forum answers and feel like this is how I'm supposed to be setting it up, but it's still not working. Something that concerns me about this attempted setup is that it still is using DHCP from the Arris modem / router, and I'm r... Read more

Hello. I just moved to Auckland, NZ from the USA to go to school at the university here, and am having a problem connecting to the internet in the university residence hall in which I am living.
Wifi is not available in the residence halls, so we need to use an Ethernet cable. When I plug in my computer, the network adapter icon says “Identifying...” for a while then settles on “Unidentified Network” with no internet access, the IP is 169.x.x.x
When I try to release and renew the IP, it says “unable to contact your DHCP server, request has timed out"
I've tried multiple Ethernet cables, both brand new.
I tried connecting to a port in a friend's room in the same building, and even in a classroom on campus, and both had the same result.
Naturally after all that I assumed my NIC somehow died overnight while I traveled here, so I went to a computer repair shop expecting to have some hardware replaced, but we plugged it in there and it worked immediately so they weren't sure what to tell me.
I've gone through pages of old threads at this forum and others like it, trying solutions but having no luck.
I've power cycled my computer, obviously I can't power cycle the whole network as it's for 200 people, but the IT people here have tried resetting it for me on their end as best they can.

QUESTION #1:
Is it better to use Win2000 Server DHCP or DHCP from my Netgear wireless router?

#1 BACKGROUND:
I am currently in the process of setting up a Win2000 server on my home network which consists of four other 2000/XP machines.
The server is going to be configured as a domain controller and will utilize the Active Directory.

Should I use the Win2000 Server DHCP or stick with my wireless router as the DHCP server? What are the advantages/disadvantages to both and which would be easier to maintain.

QUESTION #2
Is a 550mhz PIII with 256MB RAM fast enough to make a good home server running Win2000 server?

BACKGROUND #2
The server is going to have (2) 120GB Western Digital 7200rpm drives with 8MB cache for storage and a single 60GB Western Digital 7200rpm drive for the OS and few other applications.

The server's primary function is to serve as a media server with an approaching 10GB of MP3 and music video files which is continually going to grow. Disk contention is at a minimum since there are only four PC's on the network. There will also be a lot of digital photos stored on the server and will also serve as a place to perform backups from the other four networked PC's.
 

A:Win2000 Server DHCP or Router DHCP?

We have a similar setup in our office using Small Business Server, a public IP coming into our router with DHCP turned on, connected to a NIC in the internal DHCP server (which is also running ISA). A second NIC in the server bridges to the internal hub to provide DHCP services to the clients. This way we control port filtering in 2 places and with 2 levels of NAT taking place we feel secure. It may be overkill but we're concerned that EVERYONE is trying to hack into ISA and DHCP servers connected directly to public IP that this setup provides an added level of security.

Hey i got similar problem.I have dell inspiron 1501 (Vista32) and routher Linksys WRt54G.
I keep getting "local only" and "limited conectivity".I realized that the problem is in my pc because the other pc's connect to the access point without problems.I tested the following:

plugged directly to the modem=no success
plugged to the wireless routher=no success

When i looked into the info from ipconfig command i get this ip:
autconfigured ipv4 169.254.15.197

Due to that i entered ip manually something like:
192.168.1.2
255.255.255.0 and default getaway 192.168.1.1
then tried with disabled ipv6
Still nothing.Then tried netsh int test reset ip and netsh winsock reset catalog without success!
The i upgraded my wireless card drivers and routher firmware just in case,reseted the routher to factory defaults and still nothing! I really dont know what could be the reason for that.Since i bought the laptop 1,6 year ago didnt had any problems.
I think everything started after i uninstaled Norton Internet Security and using Norton cleaning utility! I instaled Eset smart security and i started to get blue screen of dead! I wasnt able to log on to windows.After uninstalation i was unable to connect to internet.

Hi all, sorry if this is in the wrong section but it was the closest one I can find.

I am setting up a Windows Server 2008 R2 server onto a network. The network has an ADSL modem router. I think I am setting up something incorrectly as I cannot get internet on my computers when the DHCP is enabled on the computer and not on the router.

My settings are as follows.

Server PC: (I set these myself manually)

IP Address: 192.168.2.1
Subnet Mask: 255.255.255.0
Default Gateway: 192.168.2.1

DNS Server: 192.168.2.1


Router:

IP Address: 192.168.2.2
DHCP Server: Disabled
WAN DNS Address: *retrieve automatically from service provider*

DHCP settings in server manager:

IP Range: 192.168.2.10 --> 192.168.2.100
Subnet Mask: 255.255.255.0
Default Gateway: 192.168.2.1
DNS Server: 192.168.2.1

I have not modified any DNS settings not entered any settings apart from the above.

I cannot for the life of me get the internet to work with these settings and I need to run a domain environment from this server so I need the DHCP and DNS to operate from the server.

If anyone is able to help me I will be eternally greatful.

Thanks

A:[SOLVED] DHCP and DNS in Windows Server 2008

Looks like your Server's setup in a loop, pointing back at itself for DNS (and Default Gateway?); you need it to pickup from an outside DNS server - your ISP, OpenDNS or whatever.

Not sure what the gateway needs to be set for, I'd suspect it should point to the router's IP - but I know almost zero about setting up a server!

Well, let's do the official stack repair, since you didn't say exactly what you did.

TCP/IP stack repair options for use with Vista or Windows 7.

Start, All Programs\Accessories and right click on Command Prompt, select "Run as Administrator" to open a command prompt.

In the command prompt window that opens, type type the following commands:

Reset WINSOCK entries to installation defaults: netsh winsock reset catalog

Reset IPv4 TCP/IP stack to installation defaults. netsh int ipv4 reset reset.log

Reset IPv6 TCP/IP stack to installation defaults. netsh int ipv6 reset reset.log

Reboot the machine.


Next, if that doesn't do it, I'd suggest a run with SFC since it's saying a file isn't found.

To get straight to the point, I've got network connectivity but no internet connection. ipconfig /renew gives the message "An error occurred while renewing interface Local Area Connection : unable to contact your DHCP server. Request has timed out."

I'm volunteering at a library. I just replaced one of the old public computers with a new Dell running Windows 7. They're all on a wired connection, and the old ones work fine. The new one is the only one with a problem.

ipconfig /all on the problematic one gives

We are moving our DHCP from one Windows 2003 Server (standard) to a new machine. Both servers are domain controllers. AD is set up and working on both servers. Everything is set up. I exported the dhcp database from the old server to the new one. All messages were successful.

I unauthorized the DHCP server on the old server.

Now when I try to Authorize the new DHCP server, I get an Access Denied message. Everything I have read is indicating that the I have to be a member of the Enterprise Admins group in order to Authorize a DHCP server.

We didn't have this group initially and I'm thinking we didn't because we are only running Server 2003 Standard. I created the group, but I'm not sure if I did it right and added Administrator. It still isn't working. Can someone please help me?

Thanks!

Hello

I hope you guys can help me, sorry this is very long and clueless. I am not techy at all.

I have 2 PC's connected via ethernet cable to a router provided by my ISP (Orange Livebox). One PC has Windows XP (hubby's) and one has Windows 7 (mine).

Until about 2 weeks ago both PC's were working fine and no internet connection problems. We lost our connection one Friday night along with thousands of other people in our area. It was fixed on Saturday but ever since then my PC has been dropping it's internet connection but my husband's PC is working normally.

My internet connection drops and will only come back on if I unplug the router and leave it off for a minute then plug it back in. Connection then works for a few hours (usually up to 7 or 8 hours) before dropping again.

I get this error in the Event Viewer when it happens:

Have contacted the ISP "support" who sent a new Livebox and ethernet cables. I thought this had worked but lost the connection again the next day. Phoned them again and they say they will test the line and get back to me (they also said this last time). They are useless and I would change ISP but my husband is ... Read more

My laptop is running Vista SP2. The machine will connect to my Belkin router with a wired connection but I have a problem setting up a wireless connection. The machine can successfully obtain an IP address from the DHCP server but it is unable to get a ping response from the gateway address or anything else on the LAN (and yes, other devices on the LAN can ping the gateway 192.168.2.1). I have tried stopping the Base Filtering Engine, running 'netsh winsock reset' and applying the fix in http://support.microsoft.com/kb/928233 but none of these has resolved the problem.

In the 'Network and Sharing Center' window, the machine is shown as being connected to 'Unidentified network', but there is a red 'X' against the onward connection to the internet. Initially, I had the same problem with the wired connection but running 'netsh winsock reset' in the command window triggered it into creating a new network location the next time it connected and then it worked happily. Unfortunately, I have not been able to repeat this with the wireless connection.

The network adapter is an Atheros AR5007EG with driver version 7.3.1.109 and the status show that is working properly. For information I have shown below the output from the command ipconfig /all:

Welcome to TSG.
We have seen quite a few issues with that adapter.
Here is a summary of things to try:

Atheros AR5007EG & AR5007
We have recently been seeing a lot of problems with the above adapters over the last few months, mainly concerning WPA and WPA2 encryption and windows Vista.

The adapter gets an IP configuration, and shows as connected, but communication is non-existent or sporadic.

Log into the Router and disable the wireless security and see if you are now able to connect to the internet and surf OK.
--- Please post back here if that works or does not work.

Here are a number of possible solutions

--- 1) In Device Manager right click on the wireless adapter and "update driver." That apparently has worked for some posters.

--- 2) Download and install the latest wireless driver from your laptop manufacturer's web site support section, as some manufactures, appear to now have a working driver available.

I hope someone may be able to tell me how to fix the problem I'm having with my modem. My modem makes a loud humming static noise while dialing to get on the internet or to talk with someone and then disconnects and ends the call immediately after dialing. Sometimes there is no static noise while dialing and then the loud humming starts immediately after dialing and the telephone call terminates after about 30 seconds. On one call, I heard someone talking from the other end of the phone line but couldn't understand what they were saying because of the loud static.
I have an IBM Aptiva computer, with a windows95 operating system and an IBM Aptiva 28.8 mwave Data Fax modem which is located right on the mother board. I bought the computer new about 5 years ago.
I'm not too familiar with technical terminology, although I have looked in every part of my computer. I looked at a lot of things under system, modem, network neighborhood, program manager and communications, but everything looks normal. IBM notified me that they don't stock this modem any longer. I'm at a complete loss of any new ideas on how to fix this problem exept to try a new modem which I'm a little hesitant to buy until I'm sure the one I have is bad. Any help I can get woud be appreciated. Thank you.

I am setting up a linux box for a server on my home network which is DHCP, I don't want to change the entire network, I just need this server to have a static IP (so that I can get port forwarding to work). I don't even know if this is possible, if I were to give the server a static IP can my router deal with it, even though everything else is DHCP? My router is a linksys WRT54GS if that helps any.
An answer to this would be much appreciated. ^_^ Thanks
 

A:Solved: Is it possible to have one computer with Static IP on a DHCP Network?

Yes just make sure it sits outside of your DHCP scope so if DHCP starts at 192.168.1.100 and has 100 seats then make the machine be 192.168.1.99 or lower or 192.168.1.200 and higher and it would be fine. Make sure to copy all other items from what DHCP would give you. E.G. DNS, Subnet mask and gateway.

I have a problem with my pc randomly locking up and having to be rebooted. I believe it has to do with the wireless card accessing my network, but I can’t figure out how to troubleshoot it. (If this is the wrong forum, please let me know!)

I have a desktop, two laptops, and a printer on a wireless network. All of them have been working fine. Then, about a month ago, I loaded a new game on my desktop, which worked entirely fine for roughly three weeks. Then last week, I tried setting up a server in the game. On my first attempt, it locked up my pc at the setup server stage, and I had to reboot. On my second attempt, I tried a slightly different configuration, and it created a local server and worked just fine.

Everything seemed okay for a couple of days, and then the game started to lag after a few minutes of play. After two or three more rounds of play, the lag was then accompanied by the pc locking up. Couldn't figure out why, so I stopped playing it.

Within a day or two, my desktop would randomly freeze without warning, with no clear connection to any specific application or time of day. This has continued to today. Sometimes the lock up is preceded by erratic behavior, such as the wireless keyboard freezing up though the companion wireless mouse will work (or vice versa) and an occasional USB connecting-then-disconnecting sound, though nothing had been touched. Sometimes the lock up is for 10 seconds or so. Most of the time, though, there are no warnings, and it ... Read more

Having trouble with my Windows 7 Ultimate (64-bit) wired LAN connection. Yesterday evening everything was fine, I was connected and doing some remote work into the office - I was playing with OpenVPN connections. I left the machine for a few hours logged on, came back and now the NIC appears dead.

I have restored windows to the point just before i installed Open VPN.

I get "Unidentified network" and "no internet connection" for my LAN connection in Network Centre. There's no gateway or ip assigned looking at ipconfig /all, just the self assigned 169.* ip

The ethernet cable is connected directly into my cable modem (note, not a router).

I have googled a lot and have tried (not necessarily in this order):

1. Ensured its not the WAN/RJ-45 cable - have connected successfully with an older laptop's LAN NIC. When switching machines i turn off both the machine and the modem for 30 secs, and typically tun network troubleshooter to reset the LAN.
2. Tested the internal NIC by pinging 127.0.0.1, loopback successful.
3. Uninstalled the LAN NIC and reinstalled it.
4. Removed all clients & protocols from the NIC's properties bar IPv4 and Microsoft Client for windows i.e. specifically removed IPv6.
5. Reset TCP/IP using netsh int ip reset c:\resetlog.txt.

I have an active directory, a DHCP server, 3 VLANs, and 2 wireless Router/AP/Repeater. I was thinking, might be the first problem, that I would put in one as an AP and one as a Repeater. The signal is there and static IP on the device works, but that is, well, it does not work for what we need it to. I tried enabling DCHP on AP but it is assigning ips to our voip phones. Really messes them up with they use get connected that way instead of the DHCP server.

So I am not sure how to set this up where a device connects to the wireless, get assigned an IP from the DHCP server and works.

I have tried several different ways, but have not hit what works.

One of my client's Active Directory server (Windows 2003 Server) went down when we installed Service Pack 2. We were able to remove the service pack and get it running again, but until then the client was without any Internet connectivity, due to their DHCP running on the Windows AD. It was a six hour nightmare.

Can a Windows Active Directory do its job without running its own DHCP service? We would like to unload the DHCP from the Windows box to a Linux box or even to the WatchGuard router, but I am not sure how well the Windows server would take this hit to its functionality (or ego ).
