Outlook can't connect to Exchange server when internet down.

[Len K]

Here is an interesting problem. I have an exchange server on SBS2003 with
about 15 clients running XP and Outlook 2003. We had a power glitch, out
about 15 seconds, and our cable internet went out at the same time (I think
someone hit a pole down the street). The server stayed up with a UPS. Most
of the clients went out. Most rebooted and started outlook ok...could send
internal e-mail. However, a few would get a message that outlook couldn't
connect due to network problems.

They were able to log onto the network ok and even browse to the server.
One system I went so far as to un-install and re-install outlook...then I
would get a message that the user couldn't be verified due to trust problems
between the server and client? What is that all about?

After the internet came back up about 3 hours later, the clients could
launch outlook and connect, after a box came up asking for their domain user
name and password. (they were logged into the domain all along).

What does internet connectivity at the server have to do with the outlook
connection, and why for only a few people?

I'm sure some guru out there has the answer...

Thanks...

I guess all the trouble is due to the unexpected powerglitch...
we got that annoying error msg talking about missing trust relationship on
several workstations here too. Don't know exactly what and how it happens,
but the solution for the concerned users is to remove their account from
Active Directory and put them back in, so the trust relationship would be
reestablished.

There has to be a better way than that...plus that doesn't explain why my
clients got access back after the internet came back.
