  62 <p>There's bad news then worse news WRT rgy_backup.</p>
  63
  64 <p>First the bad news:</p>
  65
  66 <blockquote><p>It was hoped that when rgy_backup was run on each of the clients - i.e. any machine that is not designated as a backup registry server - it would contact the primary registry server and ask "Who's the backup registry server?" then check to verify that the client was proper configured. If not, that it would update the client's notion of who is the designated backup registry server. Turns out this is  not the case! So we would have an issue of how do we properly configure all the clients.</p></blockquote>
  67
  68 <p>Now the worse news (AKA Why that CC Doctor warning about running Clearcase on a machine that uses DCHP is important):</p>
  69
  70 <blockquote><p>When I tested rgy_switchover I was surprised that it was unable to switch over any Windows desktop! Here's the output:</p>

  95     <p>I suspect that the problem is that the Windows machine name does not resolve to an IP address:</p>
