I have the same problem, excpet our ISA server (2006) is in the DMZ, and is not part of our Domain. This is also a single NIC config...
I have an SSL Exchange OWA publishing rule with the following config:
Publishing Rule ---------------- Name: Exchange OWA Action: Allow Protocols: HTTPS From/Listener: Exchange OWA To: mail (10.86.76.20) Condition: All Authenticated Users
Listener --------- Name: Exchange OWA Networks: Internal (0.0.0.1 - 188.8.131.52 & 184.108.40.206 - 255.255.255.254) Connections: Enable SSL - 443 Certificates: Used one I created use Win2K3 Certificate Services Authentication: HTML Form Authentication using LDAP to DC (10.86.76.21) SSO: Disabled
If I change to All Users on the publishing rule, I get the following error message:
'Error Code: 500 Internal Server Error. The certificate chain was issued by an authority that is not trusted. (-2146893019)'
