The other servers in the network still are not updating there time to the main server:

29 Jul 10:20:39 ntpdate[18249]: no server suitable for synchronization found


Where it states server dropped "192.168.1.1: Server dropped: no data ", does this means the main server is not responding or ignoring requests? I'm thinking the main servershould  be sending multicast packets or broadcast packets ?  Is this correct?

Just run `ntpd` on your gateway and your other computers. Then,
configure those other machines to use the gateway. On the gateway,
`ntpd` will both synchronise itself with the remote server and "listen"
for connections from your other computers (by default, if I recall
correctly). If you want to set up "peers", that is another matter
because the term implies some sort of failover / availability
arrangement (which is fine, but you probably don't need to make
things complicated unless you actually want to).
