I am unable to log on to a server in my domain. i first noticed the server was unreachable via remote desktop. I received the "'windows cannot connect to the domain, either because the domain controller is down or otherwise unavailable, or because your computer account was not found. Please try again later. If this message continues to appear, contact your system administrator for assistance" message.
Nest I went to the server console and was able to access it there. There was a message from the Symantec SMTP Gateway that it could not contact my Exchange server. I then rebooted the server and from that time I have not been able to log on. I have used several admin names and tried safe mode, RAC, restore to previous version and local computer. I can ping both the IP and the server name. I do not see it listed with my other servers (4) in AD.
This *may* be related to a recent Microsoft update I did this weekend.
The server is a Dell PowerEdge 2650 running Server 2003 and is a member server running SMTP Gateway. It is a backup gateway so is not critical (yet).
