Sorry, I really ought to write this one up in the trouble shooting blurb.

Change the following line in trio.xml from:

<rmi create-registry="true"/>

to:

<rmi create-registry="true" host-name="xxxx"/>

where xxxx is the name (or ip address) of the machine that the trio server is running on (the same value you'll specify in http://xxxx:8090/trio-applet.htm).

Cheers
Paul
