Key combination to reboot the Remote Session

Yesterday, after doing some stuff on windows server remotely, I disconnected the session and later when I logged in, it just showed me a blue screen. No icons, taskbar nothing. I waited for long thinking that server might be under heavy load, but there wasn’t any change even after like an hour. The only option is to reboot the server, but how? Ctrl+Alt+Del wont work on remote session. That’s when another key combination helped which is Ctrl+Alt+End. This brings the same prompt on remote session when you type Ctrl+Alt+Del on your local XP or 2kX.

So, after clicking those key combination, you can reboot the server. That really helped, otherwise, its annoying to call up the data center and ask them to reboot the server and wait for like 2 or 3 hrs.
