Why we use a vnc server

[Batistabomb]

Guys i had a small doubt why we exactly use a vnc server i.e; using vnc server in a lan can we see all the users desktops in my lan and see what work they are doing such as gmail chat,meebo e.t.c;

Ya u can but u need to have vnc server running on each machine on which u want to access the desktop. Secondly u need pass for each vnc server running then only u can access them.

Vnc is like remote desktop in windows.
