Custom created firewall rules for Active Directory 2003

Hi,

I am looking for firewall rules that I can import into my ruleset that will allow all the Active Directory communication between (servers and servers) and (servers and workstations).

We are busy migrating from a NT4 enviroment to AD and we still need the netbios over TCPIP and WINS traffic to be allowed as well.

Enviroment:

EPO 4.5

HIPS 7 patch 6

Re: Custom created firewall rules for Active Directory 2003

HIP 7 extension 7.0.4 should include a firewall rules template for "Typical Corporate Environment".

This will include a rules group for Windows AD Authentication.  You could use this as a baseline and run the firewall in adaptive mode on a couple of DCs to learn additional rules if needed.  A best practice is to have a consise firewall rule set, relying on the state table to handle return traffic for outgoing connections.

Also, Microsoft has several good articles:
