hi i work in a school and need to create a script that will logon all the computers in a computer at a certain time for when a class comes in, i have setup an account that starts a program when you logon but i want a vbs script or batch file that will logon the user account on each of the machines as it takes 10 mins of a lesson to get the kids logged on and off. if this isnt the right forum thread can someone point me in the right direction

Thats not really a networking thing unless your looking to log in the computers remotely. If theres some reason the kids cant just log in themselves, then your going to have a hard time as nothing will run logged out. You can log in the computers remotely all at once, however the only simple method i know of of doing this is a service called "logmein" where they have a "many2one" feature that allows you to control a bunch of computer simultaneously. Its $50/computer/year though.
