AFAIK /etc/inet/ntp.client and /etc/inet/ntp.server are templates for a
file /etc/inet/ntp.conf.

So if you want to act your Solaris machine mainly as an NTP server you need
to copy ntp.client to ntp.conf, and if your machine should work mainly as
an NTP server you should copy ntp.client to ntp.conf.

Anyway the resulting ntp.conf file should be checked to see it it lets ntpd
do what you want.

AFAIR the NTP daemon is started automatically under Solaris at boot time if
the /etc/inet/ntp.conf file exists.

This seems to indicate your NTP daemon has no reference time sources
configured, or if it works just as broadcast/multicast client it has not
received any packets from a broadcast/multicast server.

Why would you do that? Normally ntpd should use the well-known multicast
addresses which have been assigned by the IANA, i.e. for IPv4 or
ff05::101 for IPv6, depending on whether your server sends IPv5 or IPv6.
