With the advent of Vista SP1 Microsoft has removed the Group Policy Management Console (GPMC) from the mix. You cannot even install GPMC after you upgrade to SP1.
Read on to learn how to regain control with a cool little package we like to call SVS.
You can install Adminpack.msi on Vista, but with reduced functionality.
RSAT is not yet available, so how do you perform GPO management from a Vista SP1 machine?
SVS! - You simply create a .vsa for GPMC.msi and/or Adminpack.msi on a Windows XP machine. Export the layer and import it on your Vista SP1 machine.
You now have all of your management tools available again.
Thank you SVS!
