Hi all ! I have a problem with the installation of VPN server on the ISA2K Server. I need to install VPN-gateway on the ISA-Server, because I want to connect my roaming users with the office. I installed machine certificate on my test computer and on my ISA server. I had got this certificate from CA service. My CA service works in Enterprise root mode and it have been making machine certificates for all computers in my domain. I have a computer with two ethernet interfaces in my test laboratory, so i can try to connect with my network outside. So when i have turned off my internal connection and have turned on my external one, i try to connect over the VPN connection. But nothing happens ! I saw, that my computer had tried to make a communication very long time. At last, i saw a notification which have informed me that security negotiation timed out (Error 792). Can somebody explain me this situation and give any suggestions ? Best Regards Andrey Silkin
