I have a windows server 2008 machine setup and have the remote desktop connection (RDC) set to require Network Level Authentication (NLA). I can RDC from a VIsta/WIndws 7 PC with no problem. I also can RDC from a WIndows XP 32-bit PC, after add require registry settings to enable NLA support for the RDC client on the system.
The issue is that I cannot figure out how to enable that same ability for a Windows XP 64-bit machine. Up to this point I have had to use other machines to RDC to the system. I have been rather unsuccessful hunting elsewhere. So, I am hoping there is someone around that can help.
