I have ISA 2006 installed. Until this point, it has been in its own workgroup. We are changing that to being a member of a domain. I didn't want that server to have access to my domain if it gets hacked so I set it up as a child domain of my existing one.
When I try and connect, I get the following error in the server logs of the ISA server: "The user %username% has connected and failed to authenticate on port VPN5-9. The line has been disconnected."
When I use the users/group on the ISA server, I can connect. When I try and connect to the domain, it does not work. I've added my domain group to the local group (no luck) and to the VPN group directly with no luck.
