In ALL cases, the DNS server at the client level is the ROUTER's IP address,
A router isn't always a DNS server.

Although that may be the norm.  A client may be getting DNS address of the ISP or other from the router, which is the case in a Linksys router we use at work, or a router may very well have DNS server service capability in which case you would use the router address as the DNS address and then make sure that the router has an external DNS address in his table.

I'm wondering if Julians problem machine can ping the DNS address whatever it/they is/are.  And then ping the DNS from the router itself.  Also does all of his machines have the same DNS addresses?

The ISP's DNS may also be cached in the ADSL 2+ modem, as is the case with Telstra's "2-Wire" (make not connection description) modem. So the DNS address you give can in some cases be the actual ISP DNS server's addresses, the address of the port on the router or the address of the port on the ADSL modem. It is possible that either the modem or the router is blocking the required TCP/UDP DNS lookup ports in which case you have to use the cached DNS (or open the ports).
