[Samba] rpcclient shutdown with -m

[Flavio Fonseca]

Hello All,

  I used the command rpcclient shutdowninit -m MESSAGE ... 
  to shutdown windows workstations and it used to work just fine.
  After an online update the shutdown script stopped working.
  Trying the command manually I got this return error:
  result was NT code 0x00000057

  when I cutoff -m MESSAGE from the script it works fine, but I can't display 
any message to the user on the workstation.

  anyone can help?
