DNS Server config

Hi all,

I have one W2K server sitting behind a router, acting as the DNS and Web
Server
This W2K server has internal IP
192.168.1.101
The router itself is acting as a gateway with internal IP
192.168.1.1

external IP say 66.15.15.15

how many entries do I have to enter in the Forward lookup Zones ?
right now I have three entries: - web.xyz.com - (Same as parent
folder) A 192.168.1.101
- xyz.com -
(Same as parent folder) A 192.168.1.101

- (Same as parent folder) A 66.15.15.15
- [url]www.xyz.com[/url] - (Same
as parent folder) A 192.168.1.101


I have been trying to resolve this issue for a week now, please help...

Thanks in advance,
Amulet
