Ed,
 
Its best not to use up precious resources on the ISA Server by having
internal clients access an internal site via the ISA Server. Try
accessing the site directly, and test the site using a client located on
an external network.
 
There is a Q article on how you can't access internal sites with
SecureNAT clients. This may or may not be the case with Web Proxy and
Firewall clients, as I've not tested that out yet.
 
HTH,
Tom

        Running ISA Evaluation on server S1, AD/DNS on S2, Exchange on
S3.
        ISA setup with Internal/external NICs. Can run OWA internally on
S1 or S2 successfully.
        When I try from PC on external NIC I get error (403-forbidden -
the server denies the specified URL. Contact admin (12202) ISA)
        I am using IP address not FQDN  to access ISA external NIC.
