I have a school that has all of its kids in Active Directory and of course all PC's are joined to the domain. What we want to do is allow all kids K-4 to not have a password to login. Can I do this per OU and if so can someone point me in the correct direction to get this accomplished? Each grade has its own OU. Any assistance would be greatly appreciated. I am using a 2008 Domain controller hosting primarily XP machines with a few Windows 7 machines for about 750 nodes. Thanks for helping!
