Import and Apply Local GPOs

This script will import and apply a local GPO using the local GPO utility, ImportRegPol.exe, located here. The script is a wrapper that makes implementing this utility a snap. All that has to be done is to use the Microsoft Security Compliance Manager to export the desired local GPO. I wrote this script for use mainly in the MDT build. I realize there is the GPO Pack built into MDT, but what happens when you want to deploy a local GPO to machines already built or multiple local GPOs at different times in a build? This script makes that easy.

The syntax for the function is as follows:

Import-LGPO -LGOPName "User Friendly Name" -LGPOLocation "<Path_To_GPO_GUID>" -GPOType "Machine"

Import-LGPO -LGOPName "Disable Network Wait" -LGPOLocation "\\Fileshare\LGPO\{57D203F7-B8CE-47BC-920F-CECF34F6A6BA}" -GPOType "Machine"

You can download the script from here.
