On linux, i use software KVM (When on LAN and no need for SSH), on windows, nothing but the good old remote desktop, and with vista, i like it better since Micro$oft claims there is more security in it now, No time to validate there claims, especially when they release proprietary software.
So, i wrote this application once that whenever you click on it, it asks you if you want to restart the computer you click, it restarts, I wrote it mainly because Windows Vista’s task manager did not allow me to restart the computer like XP did (On XP, Click the taskbar, go for task manager, then you will find the option to restart the computer from the menu there), On Vista on the other hand it was not there.
So today i found out that there is another way, Just as convenient.
Since the local computer will catch the CTRL+ALT+DEL, you can not restart the remote machine by clicking that combination, Now i know there is another combination to open that lovely blue screen on the remote machine, CTRL+ALT+END (End is usually beside Delete), and voila, there is that little red thing in the lower right corner where you can click the arrow and restart your remote machine)
Have Fun
