A. Best practice stipulates that you shouldn't modify the Default Domain and Default DC GPOs. Instead, you should create new GPOs and link them to the relevant containers. However, if you've already modified the GPO and want to restore the default content, perform the following steps:

  1. Log on as a domain administrator to a DC.
  2. Start a command session.
  3. To reset the Domain GPO, type
    dcgpofix /target:Domain
    To reset the Default DC GPO, type
    dcgpofix /target:DC
    To reset both the Domain and Default DC GPOs, type
    dcgpofix /target:both
  4. After you enter the appropriate command in Step 3, enter Y to both prompts.
  5. Close the command window.

For example, when I type

dcgpofix /target:both

my computer returns the following output:
