Hidden Shares - NOT Hidden.

I just noticed this little detail.

I fired up my laptop using a wireless connection to my Office LAN in our
computer room. I have many hidden shares on four servers (with a $ of
course). Two servers are Win2K3 and 2 are Win2K.

When I fired up the network browser (my network places), I noticed that ALL
the hidden shares were visible when I clicked on Entire Network. Also, in
the right pane (window) it showed "Internet Connection" in the title bar.

I don't ever recall seeing this - "Ever". I'm suspecting that it is because
of the wireless connection - but I'm guessing here.

The laptop is a fully patched WinXP SP3 machine.

Out of curiosity, I fired up a laptop with Vista (yeah sorry...) using a
wireless connection, and I got the same thing. When on a wired connection,
this does not happen.

Has anyone seen this before? How can I prevent this from happening?

To be honest, we are quite concerned about this because we of course don't
want these shares to be seen/available to anyone outside our LAN.

btw: this occurs when the laptops are in the same "Workgroup" name - doesn't
occur when they are Domain Members.

Thanks.

I think it will happen when you are logged on as administrator AND the
same userid with the same password exists on the shared computer.

Thanks Brend. I tested your though by logging on with a different account
and yes, you seem to be correct. With a different account, the share does
not appear - even if the other user is a member of the local admin group.

Thanks.

Thats the way it works, for remote administration (in contrast to Simple
Filesharing using the Guest account).
It's a feature, not a bug ;-)

I learned it by trying to get running Psexec from Sysinternals.
