Subject: [ActiveDir] Exchange 2003 and Firewalls


I have a facilities that insists on having a very old 3Com Firewall
between our organizations.  On his side of the firewall is has 400 +
outlook clients, on my side I have the Exchange 2003 server and the
Global Catalog Servers.  Clients are taking an extremely long time to
connect to mail and access resources.  None of my other 9 facilities
have this problems and the only thing different is that none of the
others have a firewall between our two organizations.

What ports do they have to open to allow proper communications between
their clients and my servers?
