I'm a network administrator in the Navy and onboard the ship i'm stationed on we have a problem with users being able to logon to more than one computer at a time using there single logon wich poses a possible security issue, my question is "is there a way using AutoIt (or any other scripting program) to write a script that checks to see if a user is currently logged on somewhere else on the network and if so either log them off the first computer or immediatley log them off the current computer, hence keeping them from being logged onto more than one computer at a time in effect causing them to be using a single logon on across our network". Where would i need it to point to? how can i make it look for the current logon? how could i make it so that when it does log a person off the computer it does it safeley so there work is not lost? hopefully somebody out there has a fairly simple solution please feel free to email me at firstname.lastname@example.org i greattly appreciate any help i wll recieve in advance.
