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.

Time Warner (Road Runner) changed DNS servers, We lost internet access.

Asked by jerlo727 in Computer Servers, Broadband Internet, DSL Lines / Cable Internet

Tags:

Background:  School Environment, 60+ client computers

Server: windows 2000.  Server manages DHCP and DNS.  So client computers either had DNS set to automatically find DNS or was set to server address of 192.168.0.2.

Network:  Cable modem >> old Net gear Router >> To Switch which distributes to balance of building, one of which is the server.

Issue:

Road Runner (Time Warner Cable) made a change to their DNS addresses.  Everything worked before change, no internet access after change.  They had a window appear saying we needed to change the DNS settings to the new addresses.  They provided the new primary and secondary addresses.

I spoke with Time Warner tech support about what to do.  Not as helpful as I had hoped.  Basically told me I had to go to all computers and manually enter the new addresses.  I did that and we now have access to internet.

Multi part question.  Any help will be appreciated.

1.  I do not understand how this change from TW killed our internet access?  There were TW DNS servers before and all worked fine.  Why would the change make a difference?

2.  Is manually changing everything to the TW DNS servers the right way to go?  It solved the immediate problem, but it seems like there should be a better way.  

3.  I am thinking of replacing the router with a new one.  AND allow it to manage the DHCP and DNS for the network. Assuming I need to turn off DHCP and DNS on my windows 2000 server, what do I need to consider in order to make the switch?  OR is that a bad idea?

Thank you.
