I have 2 different customers that both have 1 PC each that will not run RemoteApps from their terminal server. This started on about 4/15/2018 for the first customer, and the second customer had the issue since at least 4/23/2018. These are established Remote Desktop Services installations with other PCs able to run the apps fine, and these PCs were able to successfully run the RemoteApps previously.
When they attempt to run the RemoteApps, it immediately pops up an error message stating "Your computer was unable to connect to the remote computer. Try to reconnect. If the problem continues, contact the owner of the remote computer or your network administrator." However, both workstations can still successfully open a Remote Desktop Session to their respective terminal servers.
I have gone through Event Viewer on the Remote Desktop Services servers and could not find any correlating events. I searched through Application, System, Security, and all of the Remote-Desktop*, RemoteApp*, RemoteDesktop*, and TerminalServices* logs in Applications and Services Logs/Microsoft/Windows/.
On the client PCs, I do find a correlating event in Microsoft-Windows-RemoteApp and Desktop Connections/Operational. Example:

At the first client, the Remote Desktop Services server is Windows Server 2016 and the workstation is Win 10 Pro.
At the second client, the Remote Desktop Services server is Windows Server 2012r2 and the workstation is Win 7 Pro.
Any and all help would be appreciated.
Thanks,
jeff
