SBS 2003 server was working fine. This morning Tuesday( 6/24) suddenly we cannot access server. No known softward changes overnight unless there was some auto update. Pings to server time out. I signed in on Server it is running but is somehow isolated from the network. Cannot access internet or other computers on intranet from server. Tried to ping gateway and tried to ping out to internet both time out. Pings to other computers on network time out. Reran earlier script for CEIWC to attempt to reset everything to old settings same results. Reran the wizard no change. Computers on the network which are usings the ip address of the router for DNS Server are able to reach Interenet. Computers on Network using the SBS Server ip address for DNS server are unable to reach internet.
Ran diagnostics on Router all pass except for " Ping DNS Server Primary IP Address: FAIL"
1. Changed server internet cable to different port on switch = no change.
2. Switch port lights and NIC lights are showing activity.
3. Any way to test NIC without just replacing it?
4. I think the problem has to be in the DNS settings
