I have a terminal services gateway set up which allows RDP to LAN computers across the internet without VPN, and now I'm trying to set up RD Web Access. The site works, I can log in, and I can see my remote apps listed. When I click on an App, it gives me the warning window with Connect/Cancel buttons. It indicates that the remote computer is my RDS server (local fqdn) and my gateway server's public fqdn. When I click connect, it asks for my credentials but it doesn't accept them. It indicates The logon attempt failed.
Any ideas?? thanks
