Mike,
Well, if you have a few thousand or less users, the CPU is probably not very
busy. However, IMail and NT can be rather disk intensive, especially if
mailboxes are large (above 50 meg). With 256M RAM, I think you might see
some disk thrashing if mailboxes exceed 128M. If you do not have any mailbox
size limits, I'd go looking for 'main.mbx' files above 50 meg and see what
you find. If they happen to match the users having problem, great. While
looking for files, I'd check all user folders for large files (they may have
other mailboxes).
Sorry, I do not know of a way to have Task Manager or PerfMon record its
data. Does not mean there is not a way, I just don't know it. Yes, if there
is some great increase in CPU or memory usage, that could be a clue.
If your customer is having the problem and talking to you while it exists,
I'd open the telnet program and try to connect to SMTP and POP3 ports to see
if you can connect and how long it takes to establish the connection.
Anything under a few seconds (say 5-10) should not pose a problem to the
client program. Do this from the Server console and you eliminate the
network. Do it from your local network and you eliminate other portions of
the network. If you can access fine from the consol and local network and
they cannot from outside, that leads me to think it is a network problem.
