XP SP2 firewall blocked our DNS Suffix GPO

OK, here is the situtation.  We use a GPO to update client's DNS Suffix.  After installing XP SP2, the firewall enabled (by default) and would block the GPO from being applied.  After we realized what exactly was blocking the GPO, we opened the Firewall for the LAN connection (left the wireless completed enabled).

Now we're thinking about what will happen when SP2 is rolled out to our entire environment.  
Is there any way to apply a pre-emptive GPO that will not allow this firewall from being enabled.  OR better yet, is there any effective way to leave the firewall enabled and get around this mess?  Please keep in mind that we still have some Win2K workstations as well, so the solution can not have any ill-affects on them.

Thank you for any help!

There are policies shipped with Service Pack 2 that will allow you to disable (or control) the Firewall.

To access them load up Group Policy Management Console on a Windows XP SP2 computer.

You can get GPMC from:

http://www.microsoft.com/windowsserver2003/gpmc/default.mspx#EEAA

Then create a new policy on that machine. It will load with the default files from xp, which include about 700 additional policies for you to set.

To disable the Firewall component in the Policy go to:

Computer Configuration
Administrative Templates
Network
Network Connections

And select

Prohibit use of Internet Connection Firewall on your DNS Domain

This will be available for anyone on your network to use, as you see fit.

One restriction with this. Although you can create the policy to include everything else on the XP Workstation the ADM Files used don't seem to be available as a seperate download. As such, when you create a policy on a Windows 2003 Server (for example) it will not include the additional policies.

Finally, you may bump into a lot of String is too long type errors when you load the Policy elsewhere. This issue can be resolved with:

http://support.microsoft.com/?kbid=842933

Or by loading on the current version of GPMC
