Scenario:
Windows 7 laptop in a Windows Domain environment is attempting a straight RDP session to a non-Domain Windows server 2008 R2. Laptop (System A) gets rejected every time using correct local Administrator account and verified correct password on non-Domain Windows 2008 R2 server (System B)
Any ideas or scenarios that may cause this kind of behavior (other than bad password which has been totally eliminated as a variable)???
Facts:
I can remotely log in to (System B) using LogMeIn and the Administrator account and password referenced above. I can also log in to (System B) from another non-Domain (System C) server using same credentials as above, without any problems. (System B) has NO GPO's applied (verified by GPRESULTS) but I cannot speak to (System A). Owner of (System A won't help out anymore so I need some possible ideas or things thatmay cause this kind of behavior)
User who has problem claims to also be able to log in to (System B) from a non-Domain Linux and Mac OSX box.
