Netman66,
I went to the Default Domain Controller Security Settings but there is a lot in there. Can you specifically direct me where to find this and how to implement this?
Thanks

Question
Windows 2003 firewall : ports for active directory replication, dns, etc...
Hello experts,
I have 2 windows 2003 Domain controllers for our domain - both firewalled with windows firewall. I have searched the internet (including this site) to find the proper list of ports to open to allow my network to function properly and I am having the following problems:
With the firewalls enabled - I can't add a new user to the domain or, add a new computer to the domain. If i disable the firewall for a few minutes I can do this. I am also getting errors with the AD replication. If I leave the firewalls off for several hours - AD replication succeeds. Obviously, this is not a secure method and I would like to set this up to work properly.
Here are the ports i have opened:
389 tcp & udp
445 tcp & udp
636 udp
53 tcp & udp
139 tcp
137 tcp & udp
138 udp
3269 tcp
3268 tcp
88 tcp & udp
135 tcp & udp
Am I missing anything?
Can anyone give me a specific list of proper settings. Please be as specific as possible and as detailed as possible.
Thank You...

You'll need to set these options:
Protect all network connections=Enabled
Allow Remote Admin exceptions=Enabled
Allow File and Print Sharing Exeptions=Enabled
Allow Remote Desktop Exception=Enabled.
You may also need to add a few ports to the exception list in there too. Here is a list of require ports for domain communication, add whatever isn't covered by the above exceptions.

If you look at the Default Domain Controller Policy, there should be new settings under Computer Configuration for the firewall. If memory serves me, there is a Standard profile and Domain Profile to select from. The Domain Profile should already be preset to allow Domain communication to succeed.
If you set this policy then you should not have to manually add the correct ports.
