Thanks a ton, Tony! You're giving me a really good understanding of this command.

Really, when I was hoping for a way to perform net use without a sharename, I was really just trying to save some effort and create a single backup drive mapping. In the end, I disconnected all my mapped drives that I'd made under my user account, and had them all get added through this batch file.

In the end, I decided to go with whatever makes Crashplan work with my NAS. You're right, I don't think the syntax of the document was correct to start with. But I simplified it greatly and got it to work.

Thanks again for your help and information!
