try disconnecting the connections that you don't want to use. Then run the wizard again, when it asks you something abotu connections to use there will be a check box at the lower left corner that says something the effect of "ignore disconnected connections" check that and it will only use the connected one. That or you could set them all up in a work group which you will do from MY computer, properties, computer name, change, and in there select work group and make sure you set them all to the same name.
I hope this is what you were asking and i hope it helps.
