I have a windows server 2008 standard installation.
Up until this morning I could RDP into it without issue. Now it's coming back with an error saying "the remote computer requires Network Level Authentication, which your computer does not support."
I'm RDPing FROM a Windows Server 2008 R2 install...
That error usually happens when you connect to it from an XP box, but this is from a 2008 R2 install that worked previously.
