Problem: RDP session disconnect and reconnect. Effects most user RDP sessions not all. Some remote users on our server sporadically gets disconnected. Their remote session freezes and they get a small window saying:
The session has been lost. Attempting to reconnect your session. Connection attempt 1 of 20.
Then they get reconnected mostly on the first try. To users that are facing this problem, this happens often.
Environment: Windows Server 2012 on Workgroup setting (not active directory). Dell PowerEdge T420 machine with 32GB Ram. CPU consumption mostly in 30%-40% range. RAM in ~60% range.
