[Another] Authentication Regjected

I manage a number of computers.  Only one has this problem.  Here is the syptom:

From the local computer I connect to this remote computer as one would expect.  Do my work and disconnect by closing the window on the local computer.  The next time I try to access this computer I get the Authentication Rejected error.  (I have the ability to remotely reboot this computer, having painfully set up the ability to do so.)

But, if, after doing my work, I exit TV on the remote computer, the next time I try to access it, I can.

Both computers are running windows 10 and TV 12.0.78716.(free license)

The remote computer is running at 99% CPU.  The remote computer is a Windows 7 that was updated to Windows 10 and the update and subsequent updates did not go so well.

I have two guesses as to the problem.  Some sort of timeout does not get resolved or there is a configuation issue.

Suggestions?
