Server 11 two machine configuration. The php web publishing deployment fails with the worker lookup dialog and the master machine can't find the web publishing/ web server machine. The master is behind a firewall with these ports open, 25 53 3389 5003 5353 16000 16001 16004 50003 50006. The Web server / web publishing server previously had a working two machine installation of server 10 functioning correctly. What's preventing the two servers from communicating?
