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!

Laptops in 2000 Windows domain get ip addresses from rogue DHCP servers

Asked by _Maddog_ in Windows NT Networking, Dynamic Host Configuration Protocol (DHCP), Windows 2003 Server

Tags: dhcp, rogue, servers, 2000, laptops

Dear experts,

I'm a relatively inexperienced system administrator, please help me understand the following problem.
In our Windows 2000 domain, laptops, which are members of the domain began acquiring IP addresses from a DHCP server that is not authorized in Active Directory.

In one of our departments, someone installed VMWare, with it came a DHCP service.
Today, all of a sudden, some of our laptop computers acquired ip addresses from that service instead of our own Windows DHCP server, I've verified that ours was the only one authorized.

How is that possible? How can I prevent that? Is there a way to find the "physical" source of this kind of problems? (I spent hours searching for the source of the problem today)

Thanks!
