Shouldn't that be the other way around ?
Your Samba AD DCs should have a fixed ipaddress (either set on the DC
or via dhcp) and the clients can have their ipaddresses set by dhcp,
they just need to update their dns records in AD.

There are a couple of parameters for the smb.conf file:

'bind interfaces only' and 'interfaces'

See 'man smb.conf' for the correct syntax.

They basically make the Samba 'server' only use the network interfaces
that you want it to.
