I've recently taken on a client who uses SBS 2003 (with exchange disabled). The firewall on the server is turned off. When i turn it on you can no longer log onto the domain. I have come across a microsoft article about the standard firewall settings not working for domain controllers.

Any advice about using the firewall on a SBS 2003 domain controller?

Hi,

How many NIC did you have in the server?

Do you have GPO in place?

You said you just took over this client, I assume you are not the one that set up this environment, what did the client say to you, has the client been able to connect to the domain before even when the firewall is switched on?

Regards

Because SBS 2003 leverages RRAS for some of it's internal features, you cannot turn on the windows firewall without breaking things. This was specific to SBS 2003. You will either want a newer OS or a 3rd party firewall.

I believe the firewall is off by default on SBS 2003.
Unless you have the Premium edition that some fool thought it would be a good idea to also have your SBS server be your firewall and router to the internet, you should leave it off.

A good perimiter firewall should suffice.

There is a hardware firewall in place, so I think we're good!  Thanks.
