Server 2003 domain - Firewall best practices

Hi experts, Im looking for some advice on what is best practice with reagrds to software firewalls on a windows domain.

We currently have a Domain Controller, 2 x Terminal Servers, SQL Server, File Server and 50 work Stations. Everything sits behind a hardware firewall, and all the workstations have windows firewall switched on. so I wanted to check is it also nessary to turn on the internet connection firewall on the domain controller and or other servers aswell.

Thanks

The internet Connection Firewall Basically is a PROXY for all your internal networked machines. It also prevents scanning of ports and resources (file and printer shares) from external sources.  If you want more control over your users internet content and access to resources then yes use it.  If it's not a huge issue to your organization then a simple hardware firewall when configured correctly can provide sufficient security from the outside world to your servers/computers.

Thanks for your comments, I think we will use it then, the DC is running dns and dhcp services, so does it make sense just to enable the firewall on the DC or would you enable it on all servers?

I think its a little more than just enabling it.  You have to plan it out....your services, ports, ect...

Do a test run when you have time to see if it would work in your environment.
