I recently migrated my ISA server to a new piece of hardware by exporting the entire configuration from the old server and importing into the new server. Yes the server name and IP addresses all remained the same...just new physical hardware. The server is part of an Active Directory domain and I had a SharePoint publishing rule in the configuration that was configured for form-based authentication to the client that worked fine before the migration. Basically Internet users would be prompted with the ISA Server 2006 login screen and after putting in their username/password they were properly directed to the SharePoint site.
After the migration it appears that if a user tries to login to that same screen, the screen reappears with an error indicating...
"You could not be logged on to ISA Server. Make sure that your domain name, user name, and password are correct, and then try again."
I'm thinking there is a problem talking back to a domain controller or the authentication configuration got mangled somehow but I need to figure it out quick. Any troubleshooting ideas? I'm going to DL and install the BPA and see if it sheds any light on this.
