RemoteApp Troubleshooting

[theeggmaster]

Hi,

 

I've got a bit of an issue with RemoteApp and I'm trying to find a way of troubleshooting it. Clients can connect to the RemoteApps internally with no issues, and can also connect using the Remote Desktop app on iOS/Android both internally and externally. However, Windows-based clients cannot launch the apps. They can log in through RDWeb and see the apps. Clicking on the apps downloads the RDP file, and opening the RDP file allows them to enter credentials. At that point, it says Starting and then doesn't do anything until I get a popup which says RemoteApp Disconnected (image is attached).

 

Any help with troubleshooting or pointing in the right direction would be gratefully received.
