samba - Feb 2004 - hiding the UNIX system name from Network Neighborhood

Hi,

Here's the deal;  Currently within our NT domain, Network Neighborhood can 
see our SAMBA server via both the "netbios" name (set with
'netbios name =
vegas' from within the smb.conf file), plus the actual UNIX system 
name.  We want our users to browse our SAMBA server  only via the
"netbios"
name and not the actual UNIX system name.  How can I configure SAMBA not to 
advertise the 'actual' UNIX system name?

Thanks,
