samba - Feb 2002 - No computers visible in network neighborhood unless adressed directly.

I am using Samba as a PDC with Windows XP clients. Everything
      seems to work ok (except for some bugs not related to this)
      except that none of the clients sees anything in the domain
      (Entire Network\DOMAIN). All computers/shares are accessible
      when brwosing \\computer. This is not the case when not using
      Samba as PDC.
