By default, java applets are allowed to create network connections with the server they were loaded from, but nothing else. This is to stop rogue applets doing bad things. And so it's getting "access denied" because it was loaded fro 192.168.0.100 and is trying to connect to 192.168.0.112.

What is 192.168.0.112 on your network?

Also, near the top of the java plug-in console there should be a line some thing like "Parameters. trio-server: ?, rmi-port: ?" - what does this read?

Lastly, please confirm what the "binding rmi:" lines say near the top of the tRio Server output.

Cheers
