I'd like to setup a secondary DNS server on my Ubuntu server. I have DNS working fine on the Ubuntu server, but I can't get the windows hosts names to propogate over to it. As an interim solution I manually added the Windows servers to the etc/bind/zones/domain.org.db That allows me to use the secondary DNS server to get access to sites outside of our network and local access to servers. When I run nslookup for a windows workstation it tells me it can't be resolved.
Here is what I've tried so far:

Went into both Windows DNS servers and allowed transfers to my Ubuntu DNS server. (checked DNS logs on both Windows servers and transfer went fine)

Changed /etc/bind/named.conf.local file on Ubuntu

FROM:
zone "domain.org" {
type master;
file "/etc/bind/zones/domain.org.db";
};
TO:
zone "domain.org." {
type slave;
file "/etc/bind/secondary/domain.org.db.";
};

I created the /etc/bind/secondary folder, but I'm not sure what rights to assign for "named" service. Also, you'll noticed I added an additional period to the end of db.

I also added the following lines to the end of /etc/bind/zones/domain.org.db

_ldap._tcp.domain.org. SRV 0 0 389 dns1name
_kerberos._tcp.domain.org. SRV 0 0 88 dns1name
_ldap._tcp.dc._msdcs.domain.org. SRV 0 0 389 dns1name
_kerberos._tcp.dc._msdcs.domain.org. SRV 0 0 88 dns1name

I'm very new to Linux so if you can walk me through this I would appreciate it.
thanks,
Carlton.
