Windows xp group policy not updating

The machine was in a domain where it got those group policy settings. Fortunately, there is a rather ingenious way to fix this problem. Hopefully this answer will get around to enough sysadmins to fix that. This solution is dependent upon the machine-in-question being dis-joined from the domain.

Remember editing the registry can be very dangerous. I dont like Paperlanter's answer, I know what he is getting at, but hes not saying it correctly Was the machine dis-joined from the domain from the domain?

Either via Active Directory or from the machine's System Properties/Computer Name dialog? This is true whether you are using the local admin account or not. I have computers that I've moved out of OU's that still keep OU's GPO's.
