Answer to my question:
========================================================================
=======
That's the default.  This ntp.conf points to server
"timeserver_name" and queries it individually: 
Sample ntp.conf file:
/etc/inet/ntp.conf:
===================
server	timeserver_name prefer minpoll 8 maxpoll 12
server	other_timeserver
driftfile /etc/inet/ntp.drift

- The "prefer" option on the first line will tell ntpd to go there
first.
- minpoll, maxpoll to indicate max/min frequency of time polling but
this is optional.
- remove all references to multicast or broadcast in ntp.conf file.
- Note that NTP takes a while to get into action so don't drop config
into place and expect everybody to be synched' in 10 minutes. typically
wait until a few hours are passed to confirm all is well. 
-If you have a firewall between subnets, leave port 123:UDP open
(or allow traffic between clients, server) for this to work


========================================================================
=======

Other people prefer a crontab job with a rdate command.
Ex: 0 * * * * /bin/rdate timeserver.at.my.site >/dev/null 2>&1
========================================================================
=======

Thanks a lot guys.

Time Server (Server A) on subnet1 and clients on subnet2.

Is there a way to force clients not to work in the  Multicast/Broadcast
mode and just go get the time from a specified server ?

All what I want to do is to say to the clients "go to pluto and sync
your time with him !"

Any help ?

Levi
