SERVERS -- General Information 86/07/08

  A  SERVER  is  a  process  that  provides  local and/or network access to some
  resource, such as the use of a hardware device like a printer.  A server  runs
  within  a  process, which may have the normal windows and pads open into it or
  be running invisibly in the background.   Servers  that  are  run  in  visible
  processes  (those  with  windows) have the same identity (SID) as the user who
  invoked them and they are terminated when that user logs out.    The  same  is
  true   for   background   processes   started   with   the   DM   command  CPO
  (CREATE_PROCESS_ONLY) entered from the keyboard.

  Some servers -- such as NETMAN, which allows a disked node  to  be  a  network
  partner to a diskless node -- need to run regardless of whether or not any one
  is  logged  in.    To  provide   this   capability,   the   DM   command   CPS
  (CREATE_PROCESS_SERVER) invokes servers that have the standard server identity
  'user.server.none'.  Processes started with CPS  run  in  the  background  and
  remain active across log outs.  Servers that need to be available all the time
  should be started by a CPS command in the node STARTUP file, although you  may
  use  this  command  from  the  keyboard,  if  necessary.    For  more detailed
  information about SERVERS, see the Administering Your DOMAIN System.
