Question about local DNS and the repair utility. I didn't setup this network, previous guy did. We are running a Windows Server 2003 that acts as our DNS server and file server. All the clients in-house have static IP's and the primary DNS is the server, secondary DNS is our static ISP IP. In the 'host' file under C:\WINDOWS\System32\drivers\etc, the DNS IP entry is listed there too. There are mostly XP SP 2 machines, but some Mac's for dev purposes. At random the XP machines won't connect to their respective mapped network drives (on the server). Different departments have access to different drives and permissions are set accordingly. Oddly enough, you won't lose an internet connection. So I don't know the moment it happens until trying to connect to the mapped drives. To fix the problem quickly I use the "Repair" utility on the NIC. It's up and running again ... until the next time. I have researched the hell out of this in Google. Even looked at the node type being "Unknown" vs "Hybrid". Tried editing the registry to fix that issue, but it didn't work. This started out as being a rare event. Now its getting more and more regular. What's going on?
