Our employees on our network can't rdp to a separate network pc over VPN. We are using an ISA 2006 Server as our gateway. The client machines are using the ISA Firwall Clients. The VPN to the client's site is extablished successfully. When you attempt to RDP to any usual client machine, it fails while the ISA Firewall client is running. If the employee disables the ISA Firewall client and reconnects the VPN and then trys to RDP, it works fine. What would cause RDP connections to fail when the ISA Firewall client enabled?
