samba - Mar 2000 - Unable to see Samba system or Workgroup in network neighborhood

I loaded CIFS onto a HP unix system and have passed all the DIAGNOSTICS.
I can map a drive to the unix system on my NT workstation but I am unable to see
the system in the network neighborhood.  I can also go to START>FIND on my NT
system and look for the unix box and find it without a problem. Can anyone help
me??
