The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Should DHCP server automatically update A and PTR record?

Asked by richtree in Active Directory, Dynamic Host Configuration Protocol (DHCP), Domain Name Service (DNS)

Tags: , ,

Domain controller (dc1) running Windows 2003 with DNS server and DHCP server.
In the DHCP scope DNS option tab, there are two choices:
[v] Enable DNS dynamic updates according to the settings below:
  (v) Dynamically update DNS A and PTR records only requested by the DHCP clients
  () Always dynamically update DNS A and PTR records
[v] Discard A and PTR records when lease is deleted
[] Dynamically update DNS A and PTR records fro DHCP clients that do not request updates (for example, clients running Windows NT 4)
(v means my current settings.)

I see that NT4 clients get IP from DHCP server, but DNS record is not updated.
I also see old DNS record in the list. For example, non-live host with some IP. Lease expired already.

Q#1. Should I choose 'Always dynamically update DNS A and PTR record' option?
Q#2. What options (above) should I use if I want to update DNS record dynamically?
Q#3. Under what situation is the first option (update only if requested by client)?

Thanks.
