While recently working on a project, I was annoyed at the fact that the wonderful copy/paste feature on RDP wasn’t working. After a bit of digging, I found the culprit and thought I’d share.
Whilst connected to the server go to Admin Tools -> Terminal Services -> Terminal Services Configuration, then double-click on RDP-TCP Connections. Under the Client Settings Tab, uncheck the Clipboard settings if it’s checked. That’s a list of services to be disabled.
