RE: Securing a High School Windows XP Computer Lab (Score 1)

Use the MMC tool (Start > Run > MMC {Enter}) to create a local security policy on one of the xp machines in your lab. Use the tool to set all of the security feature your desire. Once you have create the policy to your lab's needs, find the folder that stores the policy, usually C:\Windows\System32 and the folder is a hidden one called "Grouppolicy" so make sure you have view hidden files and folders checked in your Tools > Folder Options tab. One you have the folder, copy it to the same place on all the machines (I am assuming they are in a workgroup enviroment and not a domain). The grouppolicy hidden folder may not exist on the machines that you didnt create the policy on, just copy the hidden folder over to the same location anyways and reboot the machines. You policy should be working. With the policy you can disable users from installing, downloading and all around functionality of the system.
