We have about 20 virtual machines running Windows Server 2012. The majority (or all) of them have this strange issue, that remote desktop becomes extremely slow and unresponsive (feels like connecting to the server using dial-up) from time to time. But the issue will resolve by itself after around 20-30 minutes, and come back after a few hours or a day or two.
We're seeing this issue across VMs deployed from early this year to those deployed a few days ago. I recall seeing a similar issue on the forum a while back, but could no longer find it. Has anyone experienced similar issue?
