Netgroups don't seem to work. - Linux Setup, Configuration & Administration

For some reason, on one RedHat Linux cluster that I manage, the netgroups don't seem to work. I can "ypcat netgroup" but I can't match any entries in the netgroup map with ypmatch. For example: # ypcat -k netgroup| grep pandaboxes pandaboxes (panda,,) (panda1,,) (panda2,,) (panda3,,) (panda4,,) (panda5,,) (panda6,,) (panda7,,) (panda8,,) (panda9,,) (panda11,,) (panda12,,) (panda13,,) (panda14,,) (panda15,,) (panda16,,) (panda17,,) (panda18,,) # ypmatch pandaboxes netgroup Can't match key pandaboxes in map netgroup. Reason: No such key in map I am not observing this problem with any other YP maps. All machines are running RedHat Linux 7.3 -akop...

    Default Netgroups don't seem to work.

    For some reason, on one RedHat Linux cluster that I manage, the
    netgroups don't seem to work. I can "ypcat netgroup" but I can't match
    any entries in the netgroup map with ypmatch. For example:

    # ypcat -k netgroup| grep pandaboxes
    pandaboxes (panda,,) (panda1,,) (panda2,,) (panda3,,) (panda4,,)
    (panda5,,) (panda6,,) (panda7,,) (panda8,,) (panda9,,) (panda11,,)
    (panda12,,) (panda13,,) (panda14,,) (panda15,,) (panda16,,)
    (panda17,,) (panda18,,)
    # ypmatch pandaboxes netgroup
    Can't match key pandaboxes in map netgroup. Reason: No such key in map

    I am not observing this problem with any other YP maps. All machines
    are running RedHat Linux 7.3

    No real answer, just a data point...

    jbuchananemo$ ypcat -k netgroup
    all_hosts (zaphod,,) (flenser,,) (cerberus,,) (hobbes,,) (nessus,,) (zaphod.buchanan1.net,,) (flenser.buchanan1.net,,) (cerberus.buchanan1.net,,) (hobbes.buchanan1.net,,) (nessus.buchanan1.net,,) (nemo,,) (nemo.buchanan1.net,,)
    jbuchananemo$ ypmatch all_hosts netgroup
    (zaphod,,) (flenser,,) (cerberus,,) (hobbes,,) (nessus,,) (zaphod.buchanan1.net,,) (flenser.buchanan1.net,,) (cerberus.buchanan1.net,,) (hobbes.buchanan1.net,,) (nessus.buchanan1.net,,) (nemo,,) (nemo.buchanan1.net,,)
    jbuchananemo$

    These are a mix of Redhat 9 and Mandrake 7.2 and 8.21 machines. I did
    the ypmatch on a RH 9 machine, and the ypserver is a RH9 machine.

    At work I have 11 (supposed to be 12, one is still lost in shipping)
    RH 7.3 machines that that work fine with far more complex netgroup
    maps. They are served by HPUX 11.x NIS slaves.

    I must say that sometimes when I use the all_hosts in /etc/exports
    here at home, it doesn't always work at boot time, and I have to
    manually re-export. That never seems to happen at work.
