You know how sometimes, you’re helping someone fix a computer problem and the person just can’t tell you want you need to know. Example:
You: ok, so, move your mouse to the bottom of your monitor and tell me what you see.
Person: I see…a cow…a blue background, an X, a window that says Not Responding, some word documents, an IE button, a powerpoint button…
You: OK….do you see anything that says “Your Computer Will reboot in 15 seconds?”
Person: OHHHh, well….theres a window that says Your Computer Will reboot in 10 seconds…does that count?
You: *Bangs head on table

Yes…so, this of course is usually the way it goes :-)
So much could have been solved if you had just been able to see what their screen looked like. In some times, remote desktop wont work, remote assistance is just impossible to do…
Remote screenshot grabber lets you do that to a remote computer provided you have administrative rights on it and someone is logged on. Its a nifty tool and free too :) Check it out: Remote screenshot grabber

From the same group who made remote screenshot is someone who made remote interactive executer. This little tool lets you run programs with parameters on a remote computer provided you have administrative rights. This…now this…is a holy grail of remote installation ;) You don’t even need to walk over to the other computer to start installing, or running pings, or doing anything of the sort. ;) Check it out: Remote interactive executer
