Re: Exchange 2003, Outlook 2003, VPN Connection Issues

Another suggestion would be to look at Solar Winds, you can download and install for 30 days trial http://www.solarwinds.net/downloads/. Ethereal only needs to be installed on the same network segment as your clients. I would look at RPC traffic or communications between the OL Client and Exchange when the issue happens. Here is a link that also is useful for setting Static ports for Outlook 2007 and Outlook 2003.

I have seen issues like this previous with dedicated VPN's between sites so
I know this is strong possibility in your case. I would suggest starting at
the network layer of your VPN and start some monitoring on the Routers and
the VPN itself. Ethereal is great free product you can download and use to
start capturing packets to see actually what is going on. Without some
additonal networking monitoring its going to be hard to say its just Outlook
or Exchange as the issue since its working at all other locations without
cause. I would contact the T1 vendor again to see if they can also provide
you a line test to insure they are seeing no errors.

Thanks John. I guess Ethereal would have to be installed on the
exchange server or on a machine that has spanning port access to our
core switch? (or on the remote host) Do you have any suggestions as
to what I should be looking for in the captured packets?
