Mapping one drive to all SMB shares in Windows 7

Hi all,

I'm setting up my brand new RN104 and have got a bit stuck with SMB.

I have a bunch of shared folders (including the defaults of Music and Video).  I can access the parent of those shares with \\IPADDRESS in Windows Explorer, but I want to map a drive letter to that (so I can access X:\Music, X:\Video and so on).  The obvious command doesn't work:

C:\>net use x: \\192.168.65.6 /user:admin password
System error 53 has occurred.

The network path was not found.

And yet without a drive letter I get a success message and the share shows up in the NET USE table:

C:\>net use \\192.168.65.6 /user:admin password
The command completed successfully.


C:\>net use
New connections will be remembered.


Status       Local     Remote                    Network

-------------------------------------------------------------------------------
OK                     \\192.168.65.6\IPC$       Microsoft Windows Network
The command completed successfully.

It's not much use to me there without a drive letter though, so I took a cue from the NET USE output and tried the IPC$ share explicitly -- again, error 53.

Is it not possible to map a drive to the root of all shares in this way?  (I have to be using NET USE unfortunately as I believe it's the only way to give a Windows 7 service admin access to the drive, which I need to do for my backup software to see it.) And am I running into a ReadyNAS problem or a Windows 7 problem?

There's an obvious workaround which is to create a single "Share" folder containing "Music", "Video" etc, but that feels somewhat clumsy (and I'd lose per-share access control).

Thanks in advance!

Cheers,

Steve
