Two questions about Bind on Centos 6.5

Hello all.

I was able to create two Bind servers (Master/Slave). Everything works fine. NSLookup works, all my machines can reach the WWW, exept:

1) In order for the slave to get updated records, I need to delete the zone files from /var/named/slaves and restart Bind.

2)I have a Windows 2012 Active Dir machine and I have pointed as its DNS on my linux Bind machine. However, the DNS on the Windows AD machine is not being updated when I enter a DNS record in my Master DNS server. No matter what I try it does not pick up any changes.

EDIT !!! - I found the problem on question one. Like the moron that I am, each time I would enter a record I would not increase the serial number. However, the problem with question number two still remains :(.

What am I missing? Below is the config from my Master Bind server.

zone "sfentona.lol" IN { type master; file "sfentona.lol.zone"; allow-update { none; }; allow-transfer { 10.0.0.0/26; }; notify yes; }; zone "0.0.10.in-addr.arpa" IN { type master; file "sfentona.lol.rr.zone"; allow-update { none; }; allow-transfer { 10.0.0.0/26; }; notify yes; 

};

And here is the config from my Slave Bind server.

zone "sfentona.lol" IN { type slave; masters { 10.0.0.10; }; file "slaves/sfentona.lol.zone"; }; zone "0.0.10.in-addr.arpa" IN { type slave; masters { 10.0.0.10; }; file "slaves/sfentona.lol.rr.zone"; }; 

On all the machines Linux/Windows the firewall is turned off.
