Hi Mike
Sorry, my English is over 30 years old! Can you give me a one liner on 
plugs and HA in a S4 context?

We'd like to have a spare box with a backup of the data to substitute 
the DC/fileserver. What do you think about the possibility of syncing 
the data over to the secondary DC along with a copy of smb.conf and 
using that when the primary DC/fileserver goes down. Would the clients 
know to use the new fileserver: thinking about Kerberos here.

Cheers
