Microsoft sucks!
Having said that, we need a little more information.
1. Are all your workstations registering dynamically with the Windows
DYNAMIC DNS? Is the mail server registering with this DNS server
(actually, this doesn't have anything to do with your problem, I am just
curious).
2. Is the Mail server BEHIND teh NAT, or in front of the NAT in some
sort of DMZ? (sounds like behind to me).
On second thought, skimpy information never stopped me from shooting off
my mouth before, so here's my guess:
The NAT mapping for the mail server is not being done correctly or
consistently. In fact, suspect that the IP address for the mail server
is probably being NATed to another computer, other than the mail server.
You could fix this by forcing a static map of the private to public IP
address for the mail server such that it is always the same. As a rule,
u should do this for all server types.
HTH, and if not, flames to: [EMAIL PROTECTED]
