ISA 2004 W/Remote Desktop Configured Suddenly not working

Hello experts, here's my situation: Windows 2003 SP1 Standard with ISA 2004 Standard SP2. I have remote desktop administration configured and was working properly, I could remote in from authorized workstations and my VPN connection from outside the office.

I rebooted the server and suddenly remote desktop will not work. I have verified Security Policy is enabled, service is running from monitoring tab, also terminal services is enabled on server with admin group allowed. Firewall policy rules are in place and look fine, I had this issue once before and was fiddling around and got it working but honestly have no idea what it was I did to fix it as nothing looked wrong.

I am running out of ideas and would like to hear from anyone on this as I haven't found anything online to this point to help me.
