So a few days ago I changed the GPO (Group Policies) on the domain controller to setup our SMB network for unencrypted communication so that clients like Mac and Linux could get on SMB with the windows machine. Well these changes slowly propagated out to all the machines – only for me to find that Win2K3 ignores it completly. All the XP/2k machines could interact, but they could not interact...
