I got a problem with centOS 6.3 64-bit. I want to setup my nameserver with bind here. I am listing all my configuration

I have disabled selinux and stopped iptables.

dig and nslookup is working fine in the same machine

But here is the problem I am facing, I have windows machine, to test this dns and nameserver I set the first IPv4 DNS server to 182.19.26.92. Here is the details

Connection-specific DNS Suffix: 
Description: Realtek PCIe GBE Family Controller
Physical Address: ?14-FE-B5-9F-3A-A8
DHCP Enabled: No
IPv4 Address: 192.168.2.50
IPv4 Subnet Mask: 255.255.255.0
IPv4 Default Gateway: 192.168.2.1
IPv4 DNS Servers: 182.19.26.92, 182.19.95.66
IPv4 WINS Server: 
NetBIOS over Tcpip Enabled: Yes
Link-local IPv6 Address: fe80::45cc:2ada:c13:ca42%16
IPv6 Default Gateway: 
IPv6 DNS Server: 

when I am pining from this machine it is not finding the server.

Where as in another server with another live IP with Fedora ping is working fine.
