Windows 2000 Group Policy may be disabled by locking the policy files. Microsoft does not have sufficient plans to replace the system files to fix this problem so we developed an application that can be run on a domain to search for Group Policy files and lock them. Once the Group Policy files are locked the subsequent logins will attempt to read the Group Policy Objects but will not be able to so the Group Policies will not be propagated to the user or the machine. This can be a serious problem depending on the domain's reliance on Group Policy. More info on Windows group policy available here.
