WIN2000 Group Policy - Deny Games

sure under the policy go to,
user configuration-administrative templates- system and here is a policy named "don't run specified windows applications"

enter the executable names of the apps you want to block. the only drawback is that if the users rename the executable, then they will bypass this.

hope this helps.

Another option is to set NTFS permissions using a GPO. Navigate the Computer Configuration node through Windows Settings and Security Settings to File System. Add entries to each file or directory as appropriate and set security.

it is possible via gpo, however is this something you want for all users that use the workstation or just a particular group. if it is global; on your original image simply remove the games and associated startmenu group and use the image in your next deployment. or you could use a batch file that will do the work so you wont have to visit each workstation.
