NPS - The specified domain does not exist.

Have an issue with getting my VPN authorization to work with Radius. Seems that the connection works between NPS and Fortigate using MS-CHAPv2 but I keep getting the error "the domain specified does not exisit"

Domain Controller is Server 2008 R2
Domain Name: test.local
Pre 2003 Domain Name:
Domain/Forest Level: 2003

Network Policy Server denied access to a user.
Contact the Network Policy Server administrator for more information.

Okay looks like I posted to soon. Fixed it.

added a reg key to force authentication to the DNS name instead of the Netbios name
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\RasMan\PPP\ControlProtocols\BuiltIn\Default Domain

Key entry should be the DNS domain name.

Then noticed when restarting the server the NPS service was reporting that the domain test.local was unavailable.

Because the server is 2008 R2 and net bios is not in use I added a DNS forward lookup for the doman test.local and added the domain controllers in there.

Seems to be all good now.
