My user let his password expire:: a sysadm reset him a new password, but his authentication is still failing( he is on a Win2K machine ):: he can access a share on the PDC by providing his credentials, but does not authenticate to the domain:: Another indentical computer on his same remote network authenticates fine:: we removed his computer from the domain, and now when we try to rejoin him to the domain it can't find the domain controller, but we can ping him and he can ping us:: Event log shows a successful logon when he accesses the share with his credentials, so why does his system report the domain is unavailable or does not exist when we try to join his computer to the domain??

When you ping each other, is it by IP or computer name? Try placing an entry in the Hosts table for the Domain Controller. If this works, than you have a problem with your name resolution. Check your WINS and DNS settings and verify that they are correct.

yes, we are able to ping by either name or IP addy::both directions:: did try adding a hosts file entry--no change

Under Local Area Connection Properties/TCPIP Properties/Advanced TCP/IP Settings, uncheck Enable LMHOSTS lookup.

Do a sysprep on his machine and then rejoined back the domain.if not give him a new computer name and run sysprep before changing to the new computer name.

Sorry folks, I have to withdraw this question--found a firewall setting that had been changed--didn't have anything to do with name resolution or the PC itself--thanks to everyone who offered help, if I could I would split the points up forall of you
