I have been working with our firewall rules and group policies. If I understand this correctly if a system is assigned a group policy with a firewall rule in it, the regular firewall rules never get applied. So I can't for example use group policy to assign a user access to a server and still have all the other rules applied as well. I assume this is true as the default rule for a group policy is to allow any. I have looked and I can't find where it really addresses that in the documentation.
