Trouble Connecting to Virtual Machine through RDP

I cloned a Windows Desktop XP machine and could not access the machine via RDP.  I found that if I edited the registry with a key AllowDirectRDP=True, then I could RDP to the desktop. After researching the problem, I found that this behavior is “by design” for Virtual Desktop Manager “managed” machines. However, I do not believe the original machine was managed by the VDM, but it could have had roots in such a machine.
