Controlling the sim network via 1 PC

Guys, Im sorry to have to ask, but I cannot for the life of me remember the name (or even what it's called for that matter) of the software/system that allows us to control our entire network without having to use the keyboard/mouse of each pc in the network. I know it's an administrator function of sorts, but I couldnt find anything in a search as I used words that obviously dont corrospond with what ever it is called. I also seem to remember a discussion here not too long ago and the merits of different softwares available vs. the MS version of it.

With the 3 PCs running now it's getting old having to sit at each machine independantly to get it ready to fly.

Thanks for the point in the right direction,

Some use VNC, there is a freebie version here:
