  I would set up a server on each LAN that peers with the campus servers.
  The ntp.conf files would look pretty much like the ones on pub/xntp
  on merit.edu.
   
  I haven't any experience with running NTP on DS5000s; you might drop
  a note to ntp@trantor.umd.edu for real-life experiences.
   
  Let me know when you would like the machines configured into the campus
  server's tables.

We already have two time servers hendrix and bartok that are registered.
But our DEC 5000 (bartok) will not sync anybody even though it has the 
ntp.conf.dept (modified for our network). 

#       NTP configuration file for departmental server
#
#       Please send a message to "ntp-request@umich.edu" with the address
#       of your server and contact information (name, phone #, and email
#       address) to enable time service to your machine.

#       Save drift information in a file so NTP converges more quickly
#       the next time it runs.
#resolver /usr/local/bin/xntpres
driftfile /etc/ntp.drift

#       Peer with the two campus time servers.
peer 35.1.1.42
peer 35.1.1.91

#       Distribute broadcast time service on the local Ethernet.  The
#       "xx.xx.xx.xx" below should be set to the broadcast IP address
#       on the local Ethernet (normally 255 in the host part) and
#       the leading "#" should be removed.

broadcast 141.214.4.255


This is what happens when we try to sync a client off of it:

ntpdate: no server suitable for synchronization found


But our sun hendrix (configured the exact same way) sync's a host fine:

ntpdate: step time server 141.214.4.144 offset 146.6688333

Any idea's????
