Symptoms
Internet Authentication Server 1.0 (IAS) does not have the ability to proxy MS-CHAP version 2.0 requests, digital signatures, or allow cross-forest authentication to a computer running Windows 2000 Server.
Cause
This problem occurs because IAS was not originally designed to support this functionality.
