just got a new dell server to replace another one in a separate location and actually kept the same name but old server was using small business server and was in a separate domain. New server was using 2003 standard which is same as 4 other servers in NY. We built the new server in NY and promoted it to Domain controller so would speed up authentication in CA. Once we shipped it to CA, we disconnected old server and replaced with new one which also had same ip address. Then yesterday it kept turning off. Was wondering if it's because our vpn was down for 2 days when server was first replaced and since it couldn't see the domain in NY, maybe it caused it to turn off, maybe? Working on it remotely right now and vpn is up and running again so waiting to see first if active directory replication is correctly traversing from both sites then will see how long server stays up. Seems to turn off every 3 hours or so. Any ideas where in event viewer i could look to isolate the problem? Thanks.
