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.
