[MPICH] MPICH2 on Windows XP Workgroups and Samba networks

[DevTeam]

Hi Calin,

As far as I know it's a way found by Microsoft to avoid people using a 
simple XP licence to administrate a server. If you want to have more than 10 
connection you need to have windows 2003 server installed on your machine 
which is much more expensive ...

Regards,

Etienne
