Clients on a different subnet + DHCP

[Francisco Caliz]

    I have a simple (to explain, at least) problem:
 
  I have samba on a Solaris 2.6 server, with the basic configuration ( I
share /tmp with no restrictions ), the smbclient on another Solaris
machine on the same subnet is perfectly able to access the share, but NT
4.0 Workstations can`t do it.
 
  NT Workstations live on a different subnet (xx.yy.33.zz) than Solari`s
one (xx.yy.32.zz), and some of them can see the samba server as a member
of the network neighborhood if you find it by name, but some others
can`t do it at all. None of them can see the share, or the location of
the server (the domain/workgroup, I mean).
 
  I have run some tests to ensure the visibility between the machines,
specificaly a series of tests proposed by Andrew Tridgell, and
everything worked OK, but I suspect that these test were assumpting that
PC`s had static IP address (we use DHCP). 
 
  I don`t know how to ensure the samba server to became a member of any
NT domain, or if this is neccesary.
 
  This is the share, the only difference from a basic smb.conf:
 
[tmp]
   comment = Temporary file space
   path = /tmp
   read only = no
   public = yes
 
 
 Thank you very much.
