Hello I have a SBS 2003 R2 network. 5 XP clients and 1 2003 Stnd terminal server.
I’ve an issue where all of a sudden the clients + terminal server loose connectivity with the SBS server. It seems to happen sporadically. It started 2/25/09 and did it, 3/11/09,3/19/09,3/31/09,4/1/09,5/6/09. I’ve replaced the router with a Watchgaurd firebox, replaced the switch, and replaced the Nic in the SBS server. I installed a network monitor and pinpointed the time the network was going down but there are no issues in the SBS eventlog at that time. When it goes down it seems like the clients are unable to resolve DNS names. I was using the DNS on the Firebox but after talking to watchgaurd they said to use the DNS on the SBS server, which I’m now doing.
To be honest with you I’m out of things to check and I don’t know where to go from here to solve the problem. Any help would be much appreciated.
Thanks
Sean
