I have an ISA Server 2006 Server acting as a VPN server and it is working fine for all users.
However, there is one particular user who gets an error “916, the interface is in a disabled state.”
A similar error is also logged in the event log of the ISA Server
In Active directory, the user is a member of the "Domain Guest" groups. Other members of this group are able to VPN in fine so I don't think it is a permissions thing.
Any ideas anyone?
I know, with the same problem, I had to reinstall the VPN client. The problem was a corrupt file. That may not fix it, though.
After raising a support incident with Microsoft, the problem is solved in a rather bizarre way.
The user login in Active directory matched the name of an IPSEC Demand Dial interface I had set up which was disabled. Enabling the demand dial interface resolved the problem.
Probably a bug in the RRAS software but at least I have a work around for now
