just a further note on what Andrew is saying here with
"uid 0 is special in unix and in Samba".

You can create a new *nix user e.g. named "smbroot" with "useradd ..... -u 0 smbroot"
to assign him the uid 0".
This cmd useradd is sometimes named adduser and might take different arguments.
Sample (done as root):
  useradd -d /nodir -s /bin/false -u 0 smbroot
This created user doesn't even have a *nix homedir and a login shell - but has
otherwise the same rights as root.
But choose the options you like - at least uid 0 must be set.

Then you can add this new user to the samba user database.

  smbpasswd -a smbroot

Surely more detailed info is needed from your side.
