My guess is that the client is looking for the IP, getting the internal
address, and then the client is sending the traffic to the web proxy
service and ISA is seeing that it is a private IP and not useable on the
web thus host is unreachable.
If clients are web proxy or FW clients, all traffic is remoted to the
ISA server. The site needs to be accessible to ISA.
Is your DNS pointing inside or outside? Can ISA resolve internal
addresses?
This may be resolved by ensuring these sites are not proxied.

Hi Wayne,
Is your IIS 5.0 Or 6.0? And are your applications *.asp or *.aspx?
Because you can setup specific messages in the help section of each web
site that will display better and more complete error message
Detail.

In my remote office I have an ISA 2004 firewall that VPN's to a Rack in
our Co-location center. In the rack is our web servers, and file
servers. I have configured the networks on my ISA server and enabled
every both directions all users to communicate over the VPN back and
forth from the remote office and the rack. This all works great for
UNC, terminal server, SQL Server and everything but web server. When
calling the web servers I get:
Error Code: 500 Internal Server Error. The host server is unreachable.
(10065)
Pinging the web server from the remote office gives me the Internal IP
address of the web server, the IP in the rack. So ISA 2004 should
"know" to route over the VPN and I can accessing this web server UNC
path via that IP, and the WINs name.
Can someone give me a clue to what is going on? Is this error from ISA
or IIS?
