7.52 Why do I get the message "Can't start message server..."

  VUE relies on being able to do hostname lookups for the local host
  (i.e. both the fully qualified domain name and 'localhost').

  If your network is down or your DNS server is unreachable then
  VUE will probably fail.  This could happen at login
  (when you get the above message) or it may manifest itself by
  windows opening very slowly or not at all.

  The ideal solution is to get HP to fix this sensitivity
  but in the meantime the best idea is to make hostname lookups
  more robust by installing the 'nsswitch' patches (See question X.Y).
