I have 2 sites with ISA 2006 servers in both locations.
I have setup a site to site vpn (pptp) between the 2 ISAs
following the instructions given on online tutorials eg. http://www.isaserver.org/tutorials/Creating-VPN-ISA-Server-2006-Firewalls-Main-Branch-Office-Part1html.html
However, the site to site vpn is not being established.
I have verified that the local user accounts used in connecting the the ISAs
The error I get has no event id, :
"The connection was terminated by the remote computer before it could be completed."
From a remote client I can access the vpn in either of the 2 sites, so I
know the remote access vpn is working on both.
The logging in ISA shows the PPTP connection being allowed and initiated but closed a second later.
