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.

Thank you!

weird nslookup response

Asked by snhorsley in Active Directory, Domain Name Service (DNS)

Tags: Microsoft, Windows 2000 and Windows 2003 Server, upgrading domain to W2K3

I added 2 new W2K3 domain controller and installed a new Exchange 20003 server, in what is a currrent W2K domain,,,  i'm trying to demote the extra W2K3 domain controller, and I will be bringing in another W2K3 server (new hardware) into the domain, this is to move the domain to a W2K3 domain,,,  When i went to demote one of the W2K3 domain controllers, it would fail during dcpromo with a "The RPC server is not started" and would point to the W2K domain controller,, so out of curiosty, i did an nslookup to make sure dns was working properly,,,  on the w2k dc, the w2k3 dc, and even the clients, nslookup with the Default server pinting to the new E2K3 server but have the w2k domain controller ip address, this is on all the dhcp clients as well,, so i get:

C:\Documents and Settings\shorsley>nslookup
Default Server:  exchange.mydomain.com (new E2K3 server)
Address:  192.168.16.7 (actual ip address of the W2K domain controller)

I checked the dns records and everything appears to be correct,,, name servers point to newer W2K3 domain controller and W2K domain contollers,,,

On the W2k server, dns manager,, i do see an entry that says:

(same as parent) A 192.168.16.3 (which is the e2k3 server),,, as well as:
(same as parent) A 192.168.16.7 (w2k domain controller)
(same as parent) A 192.168.16.8 (w2k3 domain controller trying to demote)
(same as parent) A 192.168.16.3 (new w2k3 domain controller)

I know that that record was not manual create and i assume it was create when bring in the e2k3 server to do the migration, can that record be deleted?  Well first, is that what is causing my issue?
