Gpolmig.exe - Group Policy Migration
This command-line tool helps to migrate Microsoft® Windows NT version 4.0 System Policies to Microsoft® Windows® 2000. GPolMig migrates settings from Windows NT 4.0 policy files to the Windows 2000 Group Policy object structure. The location of the registry settings that implements software policy has changed in Windows 2000 and therefore the migration might not have an effect on some applications and components.
