I don't have access to Windows 2003 Server, so my involvement here is
currently limited to asking for some more information:

Once you've done this unmounting of existing shares, are you allowed to
mount multiple shares from the same server, or are you limited to one mount
at a time from the 2003 server?

Can you test whether this problem exists when using a newer kernel than the
one included in etch (e.g., the 2.6.23 from unstable)?  Since mounting with
cifs is handled entirely by the kernel, it's likely that this is a kernel
bug rather than a bug in the smbfs userspace tools.

Cheers,
