It looks like you have either a DNS issue, or lack a wins server.

If the machine is getting it's IP from DHCP, that can be an issue.  
But I also suggest that you setup a wins server on the the server to be used by windows machines to help in finding machines.

LOTS of things can cause this error:

Wrong preferred DNS servers: (most likely the cause)

Metadata from an improperly demoted domain controller:

You have just brought this server on line and have not registered its DNS SRV records properly:

A multihomed server,



So, I guess we need a little troubleshooting and a history lesson to narrow the possibilities:

Did you remove the server you are trying to contact?
Does this server you are trying to contact have multiple NICs?
Can you do an NSlookup to the FQDN of that server? (Example: Nslookup server.domain.name)
Can you telnet to the server on ports 53 and ports 137?
Is there a firewall, (software or hardware), between you and the server?
Are you trying to communicate from a remote site to the server?
Is the server you are trying to contact seen in "My Network Places"?
Have you swapped out the server with a new one and tried to use the same IP address?
Have you demoted the server out of the domain?
