asked on Microsoft Exchange not authenticating users from a trusted domain.
We have 3 domains and one Exchange server. Users from all 3 domains have email accounts on the Exchange server and are able to access their email from their home domain without any problems, usually. Yesterday users on one of the domains became unable to login in to their email accounts. As far as I can tell nothing has changed to cause this. I initially thought the problems was the trust between the domain with the Exchange server and the other domain, but after deleting the trust and rebuilding it I have the same problem. What would cause users one one domain to no longer be authenticated by Exchange?

SatyaPathak,
Thank you for the reply.
I've read both links above, and while a lot of it was a bit over my head, I don't think that's the problem. I am only having this problem with MS Exchange. All other services are working. Users are able to access shared resources such as shared folders and printers, Citrix terminal server and client server applications such as our ERP software on one domain from the other and are able to do so from both domains. The problem seems to be isolated to just the Exchange server, other domain authentication seems fine.
Thanks,
Rick

Forgot to mention, no error messages in either the system log or application on either server.
