Rejoint Domain after computer name change

Good afternoon

I'm having a little problem, I had a computer connected to my domain, We had to change the computer name to fit the new compagny standards. We removed the computer from the doamin, changed its name and tryed to reconnect to the domain (restart when required) but it refuses to connect to the domain.

We are using a windows server 2003 with a firebox. the computer is runnig XP

My Ip submask,and dns are setup ok. i cannot ping the server but in network explorer \\servername  i can see the server. we also have access to the internet.

We have tryed many solution offered on expert exchange but still no result.

Thanks alot for your time

OK
Thanks alot for all your help guys but nothing worked and since the user was in a hurry to get working with is computer we formated and reinstalled win XP and loggued right back into the domain. Not the best solution but it was my last resource.

Thank you all

Had this happen a bunch of times.  Log on to the computer under the local computer name instead of the domain.  after you've done that, go to the system properties & rename the computer again (you can use the same name & domain). then reboot.  if it still gives you problems, you will need to go to active directory users & computers & delete the computer from the list so it can re-register itself.

what is the error message you get when you try to rename the computer?

can you verify your IP address is in the same range of your domain?

also confirm you don't have any forward or reverse DNS entries for the old computer and the current IP relating to the old computer.

also, when you rename, i have the habbit of deleting the computer account in dsa and when you rejoin it just make a new account.

Start it from a ground;
1. Change PC name and join it to WORKGROUP. Restart PC.
2. In ADUC delete computer account (if exists) and re-create account in appropriate OU.
3. Login as local admin to PC and join domain (yourdomain.com)
4. Restart PC.
Hope it helps.

Glen KnightCommented:
can you do an IPCONFIG /ALL and post the results
Can you ping the server from another pc that is joined?
If so can you also post IPCONFIG /ALL for that computer

ipconfig /flushdns

then do a repair on your LAN adapter under network connections.

flush your dns, release and renew, once renew is completed try to ping your dc..

pnrhaitCommented:
If you can ping the dc then join it back to the domain,, make sure the computer name has been cleared from AD prior to rejoining

when you get a chance, check that:

the time on both the dc and the workstation are the same

if the dc is also a dns server have that dc's ip address in dns box of network config.
