Adding GPOs to Default Domain Controllers Policy

Tech-Archive recommends: Repair Windows Errors & Optimize Windows Performance

Hello:

I'm trying to configure the Windows Firewall on two Domain Controllers in my
AD test lab based on KB555381, which recommends using GPMC to create/manage
the GPO, but have run into a problem and need some assistance.

In an effort to setup this GPO, I attempted to edit the Default Domain
Controllers Policy Object by adding the firewall configuration settings
outlined in KB555381.

While the adjusted policy did get applied to the "primary" DC where I ran
GPMC from, it didn't get replicated to the "second" DC as expected.

I used the Default Domain Controller Policy Object because it seemed like
the logical thing to do since it was already there and I assumed that
everything was already linked properly, but that may not be correct.

While trying to resolve this issue, I read that editing this GPO may not be
best practice and have undone the changes I made.

These leaves me with the following questions:

1) Is adding this type of addition to the Default Domain Controller Policy
Object appropriate or should I create a separate GPO for this policy?

2) Do I need to create a new OU or can I add this under the existing Domain
Controllers OU?

3) How do I verify that the policy is properly linked to the intended
objects?

4) To ensure that the policy is pushed out to the intended objects, does it
need to be enforced or will it just replicate?

As this is my first exposure to GPMC or AD GPOs, any suggestions would be
greatly appreciated.

Thanks,

Bob
