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!

Cisco WLC Error Message - Clients Stuck on "Validating Identity" After Working for a While

Asked by kaos_theory in Wireless Technologies, Wireless Local Area Network

Tags: Received EAPOL-key message while in invalid state

System: Windows XP SP 2 client, domain joined
Authentication through RADIUS server

Error on WLC: Received EAPOL-key message while in invalid state (0)

On Client:  Works for a while, then gets stuck at "Validating Identity", and the icon flickers with a red Question Mark constantly

On RADIUS:  When IAS logging is turned on, the log file jumps in size very quickly, approx 8MB a minute, filled with the same message over and over:  <IP of WLC>,<Domain\Username>,03/12/2008,14:14:37,IAS,<name of RADIUS svr>,4128,wireless lan controller,25,311 1 <IP of RADIUS Svr>11/21/2007 15:29:44 30354085,4132,Secured password (EAP-MSCHAP v2),4127,11,8100,1,4130,0x4947454E2E4C4F43414C2F2142657468657364612F55736572732F4C6F6773646F6E2C2044656C656E61,4294967206,0,4294967207,1,4108,<IP of WLC>,4116,0,4155,1,4154,Use Windows authentication for all users,4129,<Domain\Username>,4149,authenticate wireless lan users with PEAP,4136,2,4142,0

While in this state, other issues might occur on the client, such as:

Typing "ipconfig" results in an error message that crashes the DOS window (don't have the error off the top of my head).

Rebooting the workstation resolves the issue temporarily.  Then the cycle begins anew.
