Both devices are still up and running during the black screen as shown in the uptime. We rebooted the VPN and server regularly. We have ruled out resource issues due to the less than 50% utilization.Īnyone faced anything similar ? Any help would be appreciated.Įdit: Another thing to add, during non peak hours, there were no issues reported. The server in question is running Windows Server 2012 r2, with 150 license for RDP. I was still able to manually disconnect and reconnect to the VPN.Ĭheck the Firewall for alerts, but I couldn't find anything that can help me to identify the issue either. I then upgraded my primary machine to 1903 hoping that. There were no alarms detected on the ISP end either. When I access it now using Remote Desktop all I get is a black screen in the RDP windows. Attempting to access the VM using RDP also shows the same problem. Thirty seconds later the connection is closed. But bandwidth utilization is at less than 50% before it crashes to 0 during the black screen. Weve noticed over the course of the past couple weeks some sporadic WVD logons exhibiting a black screen when attempting to logon from the RD client. We escalated the matter to ISP, thinking that its a network issue. Our VPN box which have almost 500 sessions, is also working at below 50% utilization for both memory and CPU. I've checked the memory / CPU utilization on the server, it is below 50% during peak. Windows Explorer.exe can be created by going to File > New Task. Start Explorer from Task Manager if you cant see the desktop. Once Task Manager is launched, the desktop should appear. When the issue occurs, VPN remains connected. In order to exit the black screen of death while signed in on a laptop, press CTRL + ALT + END (or CTRL + ALT +FN + END). This persisted for 15-30 mins before users are able login back into their environment. If they attempt to reconnect, they will get a black screen. The server and VPN was upgraded in order to handle the increased load.ĭuring peak hours, all the users will get booted out of the server. Run below DISM command from elevated prompt. Please Un Check RDP Window -> Display -> change try changing color depth to 24bit (or less) Run sfc /scannow from elevated prompt. Please Un Check from RDP Window -> Experience -> Persistence bitmap caching. So we are looking at alike 100-150 users connected via remote desktop to 1 physical server. Kindly have a look below settings while you taking RDP of Server. But as time goes by, the number of people remoting in has increased significantly. When using Remote Desktop Connection on Windows, its important to check whether youve set the screen resolution settings properly. This setup was working great in the initial years when there were only like 50 users. Recently, I've been encountering black screen issues when trying to remote to a server via vpn.
