I think what they are trying to say is:

Whilst wannacry will have no affect to a Samba server, if it is on a
Samba share that you connect to, your Windows computer may get infected.

The cure seems to be, turn off file sharing with the Samba server, it
might as well have said 'Go to Samba server, identify the power lead
and pull it out of the power socket' ;-)
