After W2k3 SP2 install, no authentication

After W2k3 SP2 install, no authentication…

Decided to stay up tonight to see if I could figure this out….seems it has something to do with the windows firewall on the server.

Updated with SP2, cannot log in to domain computers unless it has been logged in to before, ie, not talking to DC, but if I disable the firewall, it works fine….

This was working fine prior to SP2 installation…….
