newbie MS DNS as Secondary for BIND

[J!M]

Hello again,

This should be easy.. but I haven't found an easy answer in my 
searching. I'm setting up BIND (8.2.2_P5-9) on a RedHat Linux 
box, to run DNS for multiple domains on a DSL connection. My 
ISP agreed to run secondary for me - they are using MS DNS on 
NT 4.0, and  Iget the idea thay haven't had to do this previously. 

In my named.conf OPTIONS secion, I list the IP of their DNS server 
in 'forwarders', and for each zone, I have it in the 'allow-transfer'. Is 
this all I have to do on my end? I'm guessing that for each domain I 
have, I will have to ask them to add a zone record to their DNS as 
well...? Can someone with MS DNS experience give me the scoop 
here? What do I ask them to do now to enable this setup, and will I 
have to ask them to add a zone record for each zone I add in the 
future, or is the update "smart" enough to recognize new zones as 
well as updated zone data?

Thanks,
J!M
