Hi there,
In my environment we run 4 virtual windows server 2012 R2 plus a host on the same. Occasionally on the Main domain controller I will receive and RDP error from one of our sensors on our monitoring software (PRTG), when trying to remote in it will pop up saying, unable to connect and internal error has occured. It is very random, some days it wont happen sometimes it may happen once, it could happen 3 or 4 times at random intervals in a 20 minute period, the sensor also monitors the response time for RDP and it just seems to timeout. We have a sonicwall firewall in between the server and the outside world. I have tried changing the connection properties on windows firewall as well and other suggestions don seem to apply to my environment. Would anyone have any suggestions.
Kind Regards
Ben
