OK, I added the box to the domain. I made a rule to allow all traffic from the internal network to the local host and vice versa. I deleted the registry entries I made to set OWA to auth via the RADIUS. I set the listener to authenticate to the AD Domain. When I attempt to login from the untrusted side, I get to the form to enter the password, and enter that and am returned with page cannot be displayed with the tech stuff at the bottom: Technical Information (for support personnel) * Error Code: 403 Forbidden. The server denied the specified Uniform Resource Locator (URL). Contact the server administrator. (12202) The URL on IE's address bar is https://<IPADDIE>/CookieAuth.dll?GetLogonWrapper?url=%2F&reason=0 Do you have any thoughts on what might be occurring here?
