It's not really JRun's fault in this instance. Our networking group blocks multicast across subnets, so the traffic is cut off. I get the fact that it's one of the main reasons to have multiple subnets, but it's a pain. JRun will work fine, so long as the security.properties file is edited to reflect the search across subnets.
