W2K TS with SBS2K. .

The servers have been up and running for about 3 weeks
and everything has been working just fine but the
following has happened a few times for the first time in
the last 3 days.

When a user is logged into a TS session and has Outlook
open and is trying to do some other work normally in
Office, the whole session just hangs and have to wait
about 5 to 10 minutes to be able to close all
applications and then log off. When the user has closed
all applications and logged off and then logs on again,
evrything seems to work again.

I have got Office XP SP1 installed on the TS.

There is no specific time of day when the sessions have
hung so am at a bit of a loss as to what could be the
problem.

Thanks in advance

Antony
