Checklist: Configuring Rules for the Isolated Domain
Updated: October 11, 2012
Applies To: Windows Server 2012
The following checklists include tasks for configuring connection security rules and IPsec settings in your GPOs to implement the main zone in the isolated domain.
Checklist: Configuring isolated domain rules for computers running Windows 8, Windows 7, Windows Vista, Windows Server 2012, Windows Server 2008, or Windows Server 2008 R2
The GPOs for computers running Windows 8, Windows 7, Windows Vista, Windows Server 2012, Windows Server 2008, and Windows Server 2008 R2 are usually similar. If this is true for your design, create one GPO, configure it by using the tasks in this checklist, and then make a copy of the GPO for the other operating system. For example, create and configure the GPO for Windows 8, make a copy of it for Windows Server 2012, and then follow the steps in this checklist to make the few required changes to the copy.
Create a GPO for the computers in the isolated domain running one of the operating systems. After you have finished the tasks in this checklist and configured the GPO for that version of Windows, you can create a copy of it.
If you are working on a GPO that was copied from another GPO, modify the group memberships and WMI filters so that they are correct for the isolated domain zone and the version of Windows for which this GPO is intended.
Configure IPsec to exempt all ICMP network traffic from IPsec protection.
Create a rule that exempts all network traffic to and from computers on the exemption list from IPsec.
Configure the key exchange (main mode) security methods and algorithms to be used.
Configure the data protection (quick mode) algorithm combinations to be used.
Configure the authentication methods to be used.
Create the rule that requests authentication for all inbound network traffic.
Link the GPO to the domain level of the AD DS organizational unit hierarchy.
Add your test computers to the membership group for the isolated domain. Be sure to add at least one for each operating system supported by a different GPO in the group.
Verify that the connection security rules are protecting network traffic to and from the test computers.
Do not change the rules for any of your zones to require authentication until all of the zones have been set up and are operating correctly.
