Hi Arnold, pleased to make your acquaintance! It may not be in my position to 
say as just a fellow member of this list, but welcome!

Glad to hear that after all this time, you're making the switch to open 
source! Being in a country dominated by Microsoft (Belgium), that warms my 
heart. Open source is great, do give it the chance it deserves!

While unrelated to DNS specifically, I have used Samba for a few years now to 
do file sharing. Short of some additions needed for Apple devices, it has 
worked great so far and has done interop without a hitch.

This may have to do with priority of DNS servers - your BIND server(s) should 
be first in that list, and 2s (afaik) should be accounted for switching to a 
secondary in that list. Up to 2 DNS servers in such chain are supported in 
most networking implementations, some allow for 3 or more. Each multiple 
should be given 2s (again, afaik) as a multiplier, before the next is 
considered.
