Hello:
I am not sure if this is the right place to post this. If not please let me know, and
I can try somwhere else.
I am helping out a friend that is out of town so I didn't set up this network. Also I
am not by any means an Exchange guru.
Here is what they have:
Exchange 5.5
NT 4.0 Domain
Yesterday morning all inbound and outbound emails quit working. When I send a message
to it I get a SMTP 550 host unknown error. I called their ISP thinking it was a DNS
problem, and they said everything should be working fine.
I ran mtacheck.exe to make sure an email wasn't stuck or corrupted.
Does anybody have any ideas that might help me out? There is another domain with
another Exchange server (remember I didn't set it up) sharing the same T1 that is
working fine.
Any help will be greatly appreciated...
Thanks in advance...
Brian
