I’ve been working on a network using a single Windows 2003 standard server to do AD. After an excessive amount of time spent working on a problematic laptop, I notice that the other computers are unable to access the server. I ping both the IP address and the name of the server on multiple computers and both work perfectly, but when I go to explorer and try to do \\Server or \\Server\share all the computers on the network aren’t able to connect. All of them were able to connect earlier.
I checked the Event Viewer for things and noticed a problem with DNS. I tried fixing and restarted the service, but that didn’t fix the problem. I tried restarting the server, but that didn’t work and no problems showed up in the Event Viewer. The only thing I can think of that I did was add a Forward Lookup zone for the DNS. I haven’t had the chance to try removing the zone yet to see if that might have something to do with it, but even then that seems unlikely.
I’m still puzzled why I can’t access the server using the UNC. I tried both the server name and the FQDN, but neither worked.
Any ideas what the problem might be would be greatly appreciated.
