samba - Feb 2003 - WINS Server periodically losing entry for Samba Server

Hi there,

We have Samba running on an HP-UX 11.0 server. Our end-users are still on
Windows 95, soon to change to Windows 2000,
and therefore use NetBIOS to connect to the network share on the machine.
Occasionally the WINS server on the network 
loses its entry for the Samba server. This, in turn, causes the Win95
machine to be unable to connect to the UNIX server. The 
WINS server is configured in such a way that it is not possible to manually
add a permanent entry into its database for Samba. 
As a result, we are forced to stop and restart the smbd and nmbd daemons on
the server in order for the Windows 95 machine
to be able to reconnect. 

Is there a way for Samba to constantly broadcast, multicast, or unicast its
information to the WINS server in order for this problem
not to occur? One other note, the workstations will be upgraded to Windows
2000 in several weeks and thereby make this issue
moot.
