which wizard are you talking about - the wireless networking wizard or the computer network wizard?
You still have to set permissions for the drives if you want to move files around. If you click on one of the drives, select sharing and security and it will allow you to share the contents of this drive with others.
That is as far as my networking knowledge goes though, I can move files wirelessly between the 2 pc's which is all I want.
Someone more expert may advise further hopefully.
