REM Packet Filters for Server Hardening
REM
REM Name: PacketFilter-DC.CMD
REM Version: 1.0

REM This CMD file provides the proper NETSH syntax for creating an IPSec Policy
REM that blocks all network traffic to a Domain Controller except for what is
REM explicitly allowed as described in the Windows 2003 Server Solution Guide.
REM Please read the entire guide before using this CMD file.
