     Probably we could fine tune the switches, but I still believe the 
main problem resided on the interaction between the bacula-fd and the 
host server's network config ...

      We have decided to re-install the windows server, this time 
without enabling the hyper-v role ... will try again and let you know if 
this changes something.

     Kind regards
