We are running a single-domain, Windows 2003 SBS network. We have an additional W2K3 Standard box (which I will call SERVER2) serving as an Application, Print and File server. SERVER2 is not a DC. On a daily basis SERVER2 will disappear from My Network Places. The shares on SERVER2 are still accessible by typing in \\SERVER2\SHARE and all mapped drives to SERVER2 shares remain accessible on all computers. I can also ping it from other servers/workstations and it is resolving if I do an NSLOOKUP from workstations. The network is running WINS (on a different server) and I have the NIC configured to configure NetBIOS over TCP/IP. When I query WINS it does show two records for SERVER2 (as well as two records for the other non-WINS servers.) To troubleshoot, I took the server off the domain, cleared out all entries in DNS and WINS, and then rejoined SERVER2 to the domain. That worked for about 18 hours then it dropped off the network again. If I change properties on the NIC on SERVER2, it will become visible for several hours then disappear. Can anyone offer additional suggestions (other than wipe Windows clean and start over.) Thanks.
