I have moved my company over to a new Windows 2008 R2 domain network, from the older Windows 2003 domain network we used to be on.
As part of that, I have a Windows 2003 server, standard edition, Service Pack 1, windows server that ran IAS, (Internet Access Service), to authenticate users coming in for VPN on the older Windows 2003 domain.
I moved this IAS server to the new domain, registered it with the new Windows 2008 R2 domain as a RADIUS server, and have it up and running. However, users are unable to authenticate when they try to VPN in. The error I am seeing is the following :
Event ID: 2
Reason: The user attempted to use an authentication method that is not enabled on the matching remote access policy.
All of the users DO have "Allow Access" permissions set under the "Dial In" tab of their userid properties.
Is there something on the Windows 2008 R2 Active Directory server that I need to set, so that my users can authenticate to the new domain?
Thank you in advance,
