Can not access server by UNC but can by IP - Also cant access it by fully quilified name

here is the deal.. I have 3 servers

2000 server which is HAL
2003 DC - Daisy
then the problem server that just does backups/files server -- 147fflc

when im on the problem server i can not access the other two servers via - UNC or Fully qualified name but i can access it through IP.. I have checked all DNS settings on DNS server and they match up fine.. Kind of strange to me -- I have not changed anything in AD or am i trying to propagate so Im lost on this one.....   any assistance is greatly appreciated..

Thanks

RESOLVED
Issue has been resolved, both 2000 servers where set as domain controllers so I demoted both of them which left the 2003 server as the only domain controller and this resolved the problem.  I did this because the 2000 server with the problem was getting AD stuff from the 2000 server instead of the 2003 server.

Also
The messages in nslookup "*** Can't find server name for address 10.147.3.3: Non-existent domain" and "Server Unknown" where caused by not having a reverse lookup entry for the domain in DNS.

Thanks, for all the help.

When you run nslookup on the problem server what do you see on the first line, is it the name of the primary DNS server or an error?  Try doing some lookups from nslookup and see what you get.  What exactly do you see when you try to ping the servers?  If you could copy and paste the outputs it would be great.  Also install the Windows support tools on the server and run netdiag, again post the results.

Have you got up-to-date antivirus on this problem server?  There are a couple of viruses out there that have similar effects to that, though they would tend to block IP access as well.  Worth checking though.

From a command prompt review ipconfig /all (TCP/IP settings)
And nslookup badservername

Also try ping -a other server

Problems using Powershell and Active Directory?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why
