At some point in Windows session (usually days) I can no longer make RDP connections. When running mstsc and entering credentials, all buttons are getting disabled and the UI freezes. Existing sessions are unaffected, restart solves the problem.
I found advice to clear terminal services cache and disable sound in remote session. Have tried, it didn't help. Event log is empty.
Any suggestions how to fix it please?
Edit: OS is Windows 2008R2x64, SP1 and fully updated. Mstsc version is 6.3.9600. Issue doesn't seem to be specific to the target machine (fails for all I've tried – Win7x64, Win8.1 and Win2008r2).

ya23, Could you try unticking the smartcard option in mstsc (Local Resources > Local devices and resources > more > unticking 'Smart Cards') and retry.
I have this problem on my 2008 Sp1 rds server mstsc connecting to other servers. Once it happens once, I don't seem to be able to connect to any other servers via mstsc until I reboot. However it comes back after a few days.
You enter credentials for the remote server and then press enter, then the pointer goes to an hourglass and the buttons on the connection dialog are greyed out - but instead of opening an mstsc sesssion it just sits there. Nothing ever happens - from 1 hour +. This doesn't happen with my 2003 TS Jump server.
Nothing in the event logs at all!
But removing the Smartcard option seemed to fix it for me today. Not sure if temporary though. Give the suggestion a try and let us know.
