I upgrade my primary domain controller from windows 2000 server to windows 2003 enterprise server. Now when users try to connect to the VPN from their homes, the request is rejected. I went into the concentrator and when I do a test to the nre DC(new dc has the same ip address that the old had) I get the following error:
An error has occurred while attempting to perform the operation.
Authentication Rejected: Unspecified
Do I need to check any particular settings on the new DC? I can ping the DC from the concentrator.
Please can you give me some ideas
