Question : Computer Account not found on Domain

When logging-in to the Domain from one of our Windows 2003 servers, authenication fails with a message suggesting the computer account is not found. We can login locally OK but not to the Domain. When the login prompt is displayed, we can unplug the network cable, hit enter to login, and plug-in the network cable after Windows starts. We can then see all shared drives on the other servers.

This problem first occurred after rebuilding one of the two mirrored hard drives in the server. Before that, all was well.

This is only a problem with one Win2003 server; all other machines are communicating as expected. Pings work to and from all machines. Net View shows the computer name. Should the server be shut-down before I delete the computer name from AD? What's the proper way to delete the computer name from AD and then later add the same computer name to AD?

Answer : Computer Account not found on Domain

You are not changing the machine name you are just re-adding it to the domain.  The computer name will remain the same.

Can you ping your domain name?
i.e.
ping domain.com
