the articles that you mention are great...except I am
running Exchange Server 2000...all of these articles
relate to Excgange 5.5 and lower. Do they apply to
Exchange 2000 as well??
Also, one of the registry keys is
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\MSExch
angeDS\Parameters
I don't have the "exact" registry key...I have
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\MSExch
angeDSAccess with no Parameters subkey.

>SUMMARY
>This article describes how to set up Microsoft Outlook
Web
>Access (OWA) to connect to Microsoft Exchange Server
>through a firewall. This configuration assumes that there
>is a firewall between OWA and the Exchange Server
>computer. There are three ports that need to be opened on
>the firewall in this configuration. On the Exchange
Server
>computer, two ports need to be statically mapped. To do
>this, the ports must be opened by editing the registry.

>NOTE: The third port, port 135, must be opened on the
>firewall.
>MORE INFORMATION
>Follow the steps in this section to statically map the
two
>ports on the Exchange Server computer. The Exchange
Server
>computer that OWA points to must have these ports mapped.
>
>NOTE: One port must be mapped for the information store,
