Little Snitch informs you whenever a program attempts to establish an outgoing Internet connection.

Thanks for the info - I'll give it a try and see what it reports.

It's so strange because if I disable Port Forwarding completely ARD stops working, but no matter what I try I cannot get port 5900 to work properly.

UPDATE:

This is what Little Snitch reports on the admin machine - 5900 is not listed - is this what is likely to be causing the problem I wonder?
