Windows 2003 Server Domain Controller Firewall Enabled Communication Problems.

We operate in a W2K3 AD domain.  The domain has two DCs replicating one another.  The Primary DC is W2K3 R2 SP-2, and the alternate DC is W2K3, SP-2.  If I enable the firewall on either of these DCs, FRS will not replicating (Event ID:13508), and clients cannot resolve DNS or possibly RPC connection problems.  I can say that if the firewalls are disabled these problems go away.  I followed the steps as per article KB555381 (How to configure Windows Server 2003 SP1 Firewall for a Domain Controller) on both DCs and the communications problems still exist.  I modified the registry and opened all the suggested ports, enabled the firewalls and rebooted both DCs.  After the reboot and the firewalls enabled the same problems exist.  At this point I disabled the firewalls until we can figure out how to correct the problem.  Any feedback would be appreciated.

The recommended way to set this up is to use the Security Configuration WIzard. See http://www.microsoft.com/windowsserver2003/technologies/security/configwiz/default.mspx
There are lots of links on in the article to detailed information and downloads.
