Post Sysprep all PCs get same IP

I took an older image of ours and updated and syspreped it. Now every PC I bring it down on gets the same IP address. I have four PCs on the bench next to each other all with the same IP address.

They are set to DHCP. They do not have reserved IPs. I can release and "renew" and get the same address. On a different network, I get the 169.x.x.x address. I can set them to static then change them back to DHCP but I still get the same IP address.

Is there a solution that I can use to "fix" the problem and then sysprep and upload the image without having to go back to the old image and spending three days updating it again?

If you are getting a 169.x.x.x address then your network adapter is not picking up an IP from your network. Are you sure you have the correct driver installed for your ethernet adapter?  Maybe your update did not include the new hardware driver for the installed NIC.

Exerpt:
If the IP address starts with 169.x.x.x: Windows has assigned you an automatic IP address (Automatic Private IP address) because your Internet server provider (ISP) did not provide an IP address. This configuration prevents you from accessing the Internet. In this case, there may be a hardware configuration issue. Contact the ISP for help. See the "More information" section for contact information
If the IP address does not start with 169.x.x.x: You may be experiencing a software conflict or a configuration issue. Go to Method 3.

On my office network (a.b.0.0), I get the same office network address  (a.b.c.d) on all the PCs. If I put it on a network that doesn't have office network (a.b.0.0) access (let's say 10.22) I get the 169 address, instead of ANY a.b address.

So, it's like the IP address is hard coded in the image, but only if it can connect to the same DHCP server.

I am suspecting though that something failed in sysprep and it did not get a new SID. I have re prepped the PC and will try bringing it down again shortly.

SIDs shouldn't have anything to do with DHCP: sounds like you are having a problem with the DHCP server and not the image itself.  The only problem you get with duplicate SIDs would be problems with WSUS and SCCM.  DHCP is based on the MAC address of the NIC in the PC.  
If you do a ipconfig /all, is just the NIC listed?

@aleinss I did have a Cisco VPN network adapter (which was disabled) but I don't think it showed up under ipconfig. I uninstalled that. I will check tomorrow at work. I haven't brought down any other ghosted images since then, but I think the problem is with the machine image itself and not anything external or we would have gotten a lot of complaints.
I recently updated a number of images and after some brain racking, I remembered that this one may be the one I interrupted just after I started sysprep, so I re-ran sysprep and am uploading the image now. I will post updates in the morning.

hmmm, do you have a router between the DHCP server and the subnet that is recieiving 169.x.x.x addresses. It sounds like the clients can't reach the dhcp server and that the dhcp server cannot accomodate an address request becuase a router may not be forwarding the request properly. If so you need to ensure that the router is forwarding DHCP lease traffic correctly or set upa  DHCP relay agent to relay the DHCP information to the second subnet. That or setup a second DHCP server for the second subnet, information below:

@Binarymime This is a large network. Only the PCs I imaged are having the issue. The will only "get" an IP on the same network the image was created on,.
I noticed that I was able to get a new IP address when I shut them ALL down and waited for a little bit. But they all got the SAME DIFFERENT IP address.

Again, this isn't a network issue. It's a PC issue, maybe the are all registering the same way with the DHCP server so it thinks they are all the same PC?

Once a PC gets a lease from the DHCP server, it will keep the same IP and will renew it periodically (8 days is the default I think).  When you bring a new PC into the mix which doesn't have an existing lease from the DHCP, it will try to pull a brand new lease from the DHCP server.  I think that is where your problem is.  Your existing PCs are probably just renewing their already existing leases and therefore are probably not experiencing the problem.
If you think the image is truly the issue, I would try taking one of the PCs and just install Windows XP straight up on it.  Does it get the same IP?  If so, it's definitely not an image problem.
Here's a simpler/faster test: Burn a copy of UBCD4Win (http://www.ubcd4win.com/downloads.htm).  This will burn a copy of WinPE.  Boot WinPE, start network support, then run ipconfig.  Does it pull the same IP?  If you try the disc on the rest of the PCs?

@aleinss I had 5 of the issue PCs all running bartpe at the same time without any conflicts. I re-syspreped the image in hopes of fixing the issue, but they are all starting to come up with the same IP addresses again. It appears that whatever IP address the first one gets when it boots up into Windows is the same one the rest get.
Another possible hint. IPconfig /all shows a MAC address with all zeros.

Check this thread:
http://social.technet.microsoft.com/Forums/en/itproxpsp/thread/414b8c77-4d42-4630-bf02-4bef64763eec
I would:
Update the NIC drivers to the latest versions
Go into the properties of the NIC and make sure a MAC address is not hard coded.
If this still doesn't work, stop the network connections service. Run REGEDIT and go to HKLM\System\CurrentControlSet\Control. In the right pane, there should be a value called Config.   Delete that value.  Now restart the network connections service and wait about 30 seconds, then run IPCONFIG again.
I would also probably leave the Cisco VPN client out of your image if possible.  I have the setup.exe for it in my image so it's available when building laptops, but Cisco really monkeys around with the TCP/IP stack and perhaps it's done something very bad to your image.

@aleinss I think you are onto something. Now I just have to get the old drivers...

Now if only Intel would get off their butts and fix the driver! Excellent find on this - had I more time, I probably would have figured it out, but the fast solution was well worth the posting.

Reminds of the time that NVIDIA released a driver that basically turned off the cooling fan on their video cards (oops!).
Glad you got it working.

I guess that's worse than their recent drivers that effectively disable Remote Desktop.
