Hi folks! I am sysadmin of a 500 people industry; domain A and domain B in AD are trusting/trusted both way;
in domain A we have 2 DC W2K server SP4 upgraded from NT, 1 DC W2K Advanced Server SP4 fresh install and 1 DC W2K Server SP4 vmware-virtualized. Mail Server is W2K SP4 with Exchange 5.5 SP3.
in domain B 2 DC W2K Server SP4 upgraded.
Mail Server is shared between domains, from this morning all domain B users can login to their domain, can open network folders on domain A, but cannot open their mailbox (every time they open outlook they have a login window but login credentials don’t work). Note that from my pc in domain A I can open their mailbox. Furthermore in App event Log of my mail server I see a lot of eventid 537. Please Help me. thanks a lot in advance
