I've a domain controller running Windows 2003 fully patched. Whenever I login to remote desktop it'll login fine within a few seconds, I can then close the window or logout and then go back to it and it once again logs in fine. If however I leave it idle for ages and my session is automatically locked, I then close the window and reopen it when I need it again later, it takes 30-60 seconds (I've not actually timed it) for me to login as it just hangs with the grey desktop background.
Any idea to what could be causing this or how I could debug it?
Thanks
