Hi Ruba,
The Exchange Server definitely should not be running the Firewall
client.

Subject: [isalist] OWA Bridging mode,
http://www.ISAserver.org
Dear list,
Am trying to publish an exchange 2003 behind and ISA2004 in
bridging mode, after the FBA login screen I receive a File not found
error with the below in the log file.
If I add a web chaining rule that retrieve requests for the
internal exchange directly, the publishing rule works fine.
Is it ok to leave this web chaining rule in place or is it
actually over writing the publishing rule and working on its own? Or
else should I add an access rule between the ISA and the internal
exchange?
The exchange has a firewall client for the ISA, and it has the
ISA as its default gateway, and the ISA can ping the OWA internal IP
from the ISA correctly.
