Some of my devices are getting "Unable to register with the server at: https://<removedaddress>:444. Unexpected server result. Server code: -34. Server message Invalid Device Authentication Information."

This seems to happen after I register one computer of the same model, all subsequent machines seem to fail registration.

I am the king of generating a new GUID (probably did it 500 times in the last year). I doubt this is the problem as I've generated a new GUID on the machine with the same results.

Any Ideas?
