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!

SBS 2003 server displays "Duplicate Name Exists" at logon prompt even disconnected from switch

Asked by ccsward in WINS, File Servers, Networking Protocols

Tags: SBS 2003 system error "Duplicate Name Exists"

SBS Server comes up with the error "Duplicate Name Exists" at logon prompt which stops it from pinging anything or allowing any access on 80% of reboots.  The other 20% of the time it does everything its suppose to do (while still getting that error at Logon) but the LAN is very sluggish.  I have checked for duplicate CNames and there are none, and I have unplugged the server and rebooted with  no LAN connection and I receive this error.  It is a new DC/File Server (only one) but it was configured on a different LAN (test bed) so the IP address was changed from 192.168.1.100 to 192.168.0.4. The DHCP Server was also moved from the Linksys Router to this Domain Controller.  Is it possible that the DNS, or WINS  has the CName associated with both IP addresses?
