Apps hanging on RDP disconnect

Targets Windows
1

I have an issue that started around July 1st.

I’ve written several utility apps for work. They all live on a network share and are run on a server that I access via RDP. They all worked fine until July 1st. Since then, if I close RDP with the login session still running, they crash. Previous to July, my apps were happily still running when I RDP’d back in.

This is no doubt a Windows change, but I can’t figure out why. Any guesses?

Looks like you’re losing access to some resource when disconnecting. Have you implemented App.Unhandled event handler? You could attempt to write the stack & error details to a text file which may give you clues as to which resource you no longer have access to.

It could be this:

If it’s an Active Directory environment, check to make sure the option End a disconnected session isn’t checked under properties for the affected user in ADUC.
