I just replaced a drive on a Win2000 Server that replicates AD and issues out DHCP at one of our offices. I successfully joined it to the domain, setup range of IP's, etc, but am still having issues.

Users are unable to authenticate on it. They receive the message 'username or password incorrect' (or something like that). Changes made on the main domain controller seem to take forever to trickle down.

The most significant entry in the DNS Server Log is Event ID 7062: The DNS Server Encountered a Packet Addressed to Itself. At least, I think its significant.

The Directory Services Log shows numerous Event IDs 1265: The attempt to establish a replication link with parameters failed with the following status: The DSA operation is unable to proceed because of a DNS lookup failure.

Does this make any sense to anyone? I feel like its something very simple that I am overlooking.

Thanks in advance.

EDIT - Window 2000 Server SP4, one NIC only.

EDIT 2 - I should mention that I have Googled the issue, the event id's, and have not found a solution that works for me

Event ID 7062 can happen if you have two NICs on the server; I think you need to disable one but do Google on "event id 7062 two nics" for more info. – gravyface Apr 28 '10 at 14:07
only on NIC...will edit post – cop1152 Apr 28 '10 at 14:34

When you say the server "replicates AD", do you mean it is a domain controller? Is it also a global catalog? You mention you joined the server to the domain but don't mention doing dcpromo. If it is a domain controller, run dcdiag on it and review the results. – icky3000 Apr 28 '10 at 15:40
