I've found the registry keys for the Windows XP ICF Firewall Configuration. It's located in HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\SharedAccess\Parameters\FirewallPolicy. That's for everyone's reference. However, I wasn't looking for that registry key. I was looking for the registry key that contains the same type of configuration, except specific to a adapter. Does anybody know where this is? Thanks in advance.
