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.
