Our RDS environment is running in Azure on Server 2016 managed by our MSP.
We are having client-side issues with RemoteApps where one or more windows in our RemoteApp session will cease to refresh the window contents or to accept keyboard input. The endpoint's keyboard works fine.
The applications are running just fine on the RDS as you can see if you shadow the user's session. However, the user does not see their applications doing anything, so to them their applications have hung. The user CAN open taskmgr.exe by using
ctrl-alt-end sometimes to kill individual apps then relaunch them, but sometimes one or more windows does the same thing again.
A WORKAROUND is to roll back to Windows 10 1703's mstsc.exe and mstscax.dll, but that's not a solution... JUST A WORKAROUND. As we know, old versions don't get patched for security updates & other bug fixes.
We need the attention of Microsoft engineers responsible for mstsc.exe and mstscax.dll to fix it to remove the issues introduced since 1703's release.
Please help!
