Microsoft DNS Server in Production Environment - Benefits.

1. 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.
   
2. DNS supports Secure Dynamic updates. Unauthorized access is denied.
   
3. Exchange server needs internal DNS or AD DNS to locate Global Catalog servers.
   
4. 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.
   
5. 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.
   
6. Moreover,�you can use NT4 DNS with Service Pack 4 or later. It supports both SRV record registration and Dynamic Updates.
