Click OK.4.

Change the GPO Status

The new GPO appears in the left pane under the specified domain.

Select the policy proxy GPO.1.

In the right pane, click the Details tab, and then change the GPO Status to User configuration

settings disabled. This minimizes the parts of the GPO that are applied, so that users can log on more quickly.

Clear Automatically detect configuration settings.5.
