Can you force local NTP server to be accepted as "suitable"?

Is there some way to force the NTP server on a brand-new install to be "suitable" to sync other servers from? (I'm more concerned with synchronization between machines, and less concerned with what the actual time they sync to is)

For example, whenever I install fresh from the Fedora DVDs and try to time-sync between servers (ntpdate -u [IP_of_my_new_system]), I get an error like:
no suitable servers found
These machines are not attached to the internet, and I don't want to wait every time (dunno how long is required, but I usually wait an hour or so) for the NTP server to accept itself as valid.

ntptrace(8)						      System Manager's Manual						       ntptrace(8)

ntptrace - Traces a chain of NTP hosts back to their master time source SYNOPSIS
/usr/sbin/ntptrace [-dnv] [-r retries] [-t timeout] [server] OPTIONS
Turns on some debugging output. Turns off the printing of host names; instead, host IP addresses are given. This may be necessary if a nameserver is down. Sets the number of retransmission attempts for each host; default = 5. Sets the retransmission timeout (in seconds); default = 2. Prints verbose information about the NTP servers. DESCRIPTION
The ntptrace command determines where a given Network Time Protocol (NTP) server gets its time from, and follows the chain of NTP servers back to their master time source. If given no arguments, it starts with localhost. The following is an example of the output from ntptrace: % ntptrace localhost: stratum 4, offset 0.0019529, synch distance 0.144135 stratum 2, offset 0.0124263, synch distance 0.115784 stratum 1, offset 0.0019298, synch distance 0.011993, refid 'WWVB' On each line, the fields are (left to right): the host name, the host's stratum, the time offset between that host and the local host (as measured by ntptrace; this is why it is not always zero for localhost), the host's synchronization distance, and (only for stratum-1 servers) the reference clock ID. All times are given in seconds. (Synchronization distance is a measure of the goodness of the clock's time.) SEE ALSO
