Attempting to replace existing Winidows 2003 RADIUS server with new 2012 R2 NPS/RADIUS Server. RADIUS server used for 2nd Factor SafeWord authentication. All policies and settings replicated to new NPS server. NPS server has been registered w/ AD (child.domain.com).
When testing w/ NTRadPing Utility, continually get response: Access-Reject. Event ID 4402 "There is no domain controller for the domain domain.com" logged in System Log on NPS server.
Unable to locate any reference to issue w/ child domains. Not sure if this error is perhaps a red herring of some sort.
