Remote desktop connection

when i try to connect to a computer using remote destop connection it goves the error

"The remote session to the remote computer was ended by means of an
administration tool. Your administrator might have ended your connection."

When I look for info on debugging this the only thing I see is that the
admin may have disconnected the user, this is not the situation. I also
looked at the registry for the following: HKLM\Software\Microsoft\Windows
NT\CurrentVersion\WinLogOn\AutoAdminLogon and saw that the value was 0.

Any other ideas would be appreciated.

Thank you,:
