I thought I'd document that so you have the info here: There are reports that restarting the Audio Service on the server rectifies the problem, but it didn't work in our case. These servers were running as Virtual Machines in an Esxi 6 U2 environment and all users are using UPDs (User Profile Disks). Not good in commercial environment.Īfter much research, I thought I'd consolidate all my findings in this post in the hope it saves you, the reader, the same pain. The only thing that managed to get the servers operational again was a reboot. I had read about this problem, but never witnessed it first hand. One of our clients recently started to experience the dreaded RDP Black Screen issue on their Win 2016 servers.
