Hello, I have some troubles making VPN work and I hope someone can help me out.

We have one domain, with a Windows 2003 + ISA 2006 server (ISA).
Then we have a Windows 2008 server that's the PDC and also Radius server.
We want to use client-certificates to log on, using EAP.

We migrated the PDC from an existing Windows 2003 server with IAS. Most of the settings are probably oke, but I still cannot connect to our VPN. On my Win XP SP3 client I get error 691.

Earlier I got some Radius errors like:

The connection attempt did not match any connection request policy.

and

The connection attempt did not match any network policy.


but those are fixed. Now I get this error in the Event Log on the Radius server:


Authentication Details:
Proxy Policy Name: VPN Connections
Network Policy Name: -
Authentication Provider: Windows
Authentication Server: server1.INSUMMA.local
Authentication Type: EAP
EAP Type: -
Account Session Identifier: 323233
Reason Code: 22
Reason: The client could not be authenticated because the Extensible Authentication Protocol (EAP) Type cannot be processed by the server.


I checked and saw that the Extensible Authentication Protocol service is running (although I don't know if that's required).

Does anyone know how to solve this? I already configured the connection request policy to have it accept EAP (with certificates and MSCHAP v2).

Thanks in advance!
Jeroen
