We're having some intermittent issues with our NAV RemoteApp client not opening correctly. The page doesn't fully render and the window cannot be moved around the screen, the only solution is to end the mstsc process. It looks like this:
I've found that this often happens if the user is listed as "disconnected" Under Server manager > Remote Desktop Service > Connections > QuickSessionCollection
If I log the user off, they can launch the RemoteApp a 2nd time no problem. As a workaround I created a GPO that immediately logs off a disconnected session. This has resolved 90% of the occurrences for this problem but does still occasionally happen.
Network doesn't seem to be the cause as it happens on the local Gb LAN just as frequently as our VPN users and no packet loss is occuring between client and server.
Any suggestions? Cheers!
