Firewall – How to backup and restore the Windows 2003 Firewall Settings

Windows Firewall/ICS and RRAS often don't play nice with each other. It has something to do with an IPNAT.sys conflict as mentioned in that article. If you don't want Windows Firewall running on that box at all, your best bet will be to do the following:

Disable RRAS (temporarily) by going to Administrative Tools -> RRAS, right click on your server name, click 'Disable...'

Go to your server's network connections, open up the properties box, click on the 'Advanced' tab, click on the 'Settings...' button for Windows Firewall. Turn Windows Firewall off. Click ok, etc.

Go back to the RRAS config window, right click on your server name again, click 'Enable...' and test things out.

Sysadmin1138 is correct if it's domain-integrated. If not, you will need to look into exporting and re-importing the records. Look here for an example command to do this.
