Re: DNS as it relates to DNS

LOL you simply cant do this. you can never *guarantee* that the right server will be used for name queries. maybe the DC is busy, doesnt respond quick enough and a request for a logon server is sent to the internet... dont be silly.

dhcp should ONLY hand out AD DNS servers. have those dns servers conditionally forward internet requests to public dns servers

Good morning!

I continually run into this issue with my colleagues so I am posting here so that others might give their thoughts and opinions on this subject....

What exactly is the problem with providing computers that are joined to an AD environmnet (WIN2003 in most cases...some WIN2003 R2) with Public DNS information in the TCP/IP configuration information?

Meaning, DHCP (a Windows Sever) hands out an IP Address lease with all of the usual suspects....Options 003, 006, 015, 044 and 046. When handing out the IP Addresses for the DNS Server (let's say that there are two Domain Controllers in this single AD Domain / Forest, both of which are running DDNS) what is wrong with handing out those two internal IP Addresses as well as two Public DNS Servers to all of your workstations (let's just say the IP Addresses of the two DNS Servers that you ISP provides you)?

What difference does it make if you hand out the Public DNS Servers' IP Addresses as long as the "Prefered DNS Server" is one of those two internal DNS Servers and the "Alternate DNS Server" is the other internal DNS Server?

Thanks all!

Cary
