First just to be clear Poser only does full frame renders via the Queue Manager, it does not break it into little pieces to send to the different computers.  Second make sure your version of Poser and the Queue Manager are the same build number.  Third once you start the Queue Manager and wish to stop it use the Exit option on the Menu otherwise just clicking the close X button shuts down the interface, but the Queue Manager is still running.  Fourth you can only have one version of Queue Manager running at the same time.  That is either Queue 11, Queue 12 or Queue 13.  The reason is they use the same ports to talk to each other with.  Fifth make sure they are on the same network and subnet.  Normally not a problem in a home network, but could be a problem in a business network.  Sixth make sure the Firewall allows the Queue Manager to talk on your network.  This one will cause the most problems as the Firewall will prevent communication, but you will have no indication.   Again, normally you are asked to allow the Firewall to allow traffic in a home environment but maybe not in a work environment.
