Do you have Network Discovery turned on?

Yes, the Vista machine, the Vaio, does have network discovery turned on.

What a pain this whole thing is lol.

Thanks for your help. Am I overlooking anything else? See the above post regarding the results of my ping tests.

The Vista machine is the remote machine. It has NO printer attached. Rather, it wants to print to a Canon MP500 printer that is physically attached to an XP desktop.

Even though there is no physical connection between the Canon printer and the Vista machine, is it possible I still might need a Canon printer driver for the Vista machine? I wouldn’t think so, but I want to be sure.

I ***CAN *** print from the Vista machine to the Canon printer, if the latter is physically USB-attached (again, for what it’s worth). But I can’t print from the Vista machine over the network to the Canon.
