My mail says that it is not a really good idea to mess with the default domain policy and the default domain controllers policy. If someone in your organization has and you want to return it to normal you can use the following commands.
○ Default domain DCGPOFIX /TARGET:DOMAIN
○ Default DC DCGPOFIX /TARGET:DC
○ BOTH: DCGPOFIX /TARGET:BOTH
Description: Recreates the Default Group Policy Objects (GPOs) for a domain
Syntax: DcGPOFix [/ignoreschema] [/Target: Domain | DC | BOTH]
