Cannot see server when browsing network, network mappings fail also
Hi all
I have a weird problem. We have a server 2003 AD domain with several local servers.As of a couple of days ago I cannot browse one of the servers on the network and drive mappings to it fail with "the specified network name no longer available". I can RDT to it using its IP but not its DNS name. I have deleted the DNS A record from the DNS server and run the register DNS command on the affected server which has recreated the A record. It also has a valid reverse lookup record.
What could be causing this? I have not changed the IP or anything.
thanks
Tracy

Hi Korbus
Which machine should I run the NSlookup on and what commands?
ALso, this is a VMware virtual server on a IBM blade S so the network port thing does not apply in this case.

I'd run nslookup on amachine that cannot contact the server properly.

I tried it and it fixed the problem :)
Do you see any dns or similar errors in the vent logs when this occurs? I'd check both the dns server's logs, and the "lost" machine's logs.
ipconfig /flushdns, on a network machine will make sure the changes (or resets) you do on the dns server go through to the clients machine.
another thought: problematic switch port. move the server to a different port on the network switch.
