This article explains about using DNS Server in production environment.
The DNS which ships with Windows 2000/2003 server. The built-in application or component services of Microsoft are best to use in Production Environment. There are couple of benefits using Microsoft DNS Server.
DNS supports Dynamic registration of SRV records registered by a Active Directory server or a domain controller during promotion. With the help of SRV records client machines can find domain controllers in the network.
DNS supports Secure Dynamic updates. Unauthorized access is denied.
Exchange server needs internal DNS or AD DNS to locate Global Catalog servers.
Active Directory Integrated Zone. If you have more than one domain controller (recommended) you need not worry about zone replication. Active Directory replication will take care of DNS zone replication also.
If your network use DHCP with Active Directory then no other DHCP will be able to service client requests coming from different network. It is because DHCP server is authorized in AD and will be the only server to participate on network to provide IP Address information to client machines.
Moreover, you can use NT4 DNS with Service Pack 4 or later. It supports both SRV record registration and Dynamic Updates.
Using Microsoft DNS gives the following benefits:
If you implement networks that require secure updates.
If you want to take benefit of Active Directory replication.
If you want to integrate DHCP with DNS for Low-level clients to register their Host records in Zone database.
