I need to turn off the domain policy that enables the firewall on all client computers. I am using Small Business Server 2003 R2. I have installed a new application on the network that needs to use a specific port to return information and the client computers firewall is blocking the port. I can not find the policy setting that disables this for the domain. Can anyone help? Thank you.

Look in "Computer Configuration\Administrative Templates\Network\Network Connections\Windows Firewall" where you can define exceptions and open the port you need.
