Leaving aside two areas which could cover a multitude of complications 
should you pursue them, namely

1)  You start setting various security settings and make your ntp server 
effectively unreachable, or

2)  the ability of your local server to multicast time data,

your local ntp server should look like any other ntp server to which you 
have access (other than for less latency and jitter should your network 
be "normal").



in the ntp.conf of your client machines and see what happens.  The 
"peers" query from the ntpq program should let you know if you have 
success or have somehow locked yourself out / blocked access.

Feel free to give us specifics of what you're doing if this doesn't work.

BTW, the above assumes that you mean setting up your various local 
machines to all use ntpd, but not all query outside machines.  If this 
isn't it, you're going to have to tell us what you mean by "hook up my 
machines to the machine running the ntp server."
