After reinstalling several versions of pms and java and deleting the pms.conf file and trying an adjacent computer with the same problem I am at a bit of a loss as to what to do next. The ps3 is set to detect media servers. Forcing the network interface or ip also did not work neither did resetting the router or disabling the firewall completely. This problem appeared about 2 weeks ago.
Any help on what to do next is appreciated.
