Samba shares - not wanted

OES Linux SP1 with EVMS/NSS volumes. So far so good. Now, one XPPro
workstation with Client32 491SP1 maps all its drives correctly to the NW
servers but when mapping to the Linux box the drive shows up as:

(L:) Data on 'Samba 3.0.4-SUSE (Fs2)'

Just this one w/s, none of the others. Neither the Novell Samba nor the
Linux Samba Server is loaded on the Linux server. Again, only affecting
this one workstation so I suppose it is something specific to the w/s
and not the overall config of the server. Any ideas?

Thanks
