RemoteAPPS Folder is empty after reinstalling .NET

Question

Hi

We had to re-install .NET for a PDP of the APP we use (Quickbooks) on our RDP server... doing so broke RDP.

The RemoteAPPS folder emptied itself and I can't figure out how to repopulate it.

On top of it, our certificates expired. I created new certificates but it seems the shortcut on the various computers connecting to the RDS server are still using the expired certificate.

Only users that can operate right now are those that were connected prior to expiry.

Any help would be greatly appreciated!
