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!

LDAP Bind was unsuccessful - Event ID 8026

Zones: Active Directory, ISPs & Web Hosting, Exchange Email Server

Tags: 8026, event, ldap, id, bind

Dear All,

I'm facing some serious problem with exchange 2003 (SP2) server, almost two - three times a day we cant able to connect exchange server. I check the event logs and it logs event id 8026 LDAP on every 15 sec.

Event Type:      Error
Event Source:      MSExchangeAL
Event Category:      LDAP Operations
Event ID:      8026
Date:            3/7/2007
Time:            12:50:44 AM
User:            N/A
Computer:      EMAILSERVER
Description:
LDAP Bind was unsuccessful on directory dataserver.atlantis.co.ae for distinguished name ''. Directory returned error:[0x51] Server Down. DC=atlantis,DC=co,DC=ae

For more information, click http://www.microsoft.com/contentredirect.asp.

Scenario::
We have two windows 2000 server namely dc1 and dc2 (these are not the real names). dc1 is the primary domain controller and dc2 is additional domain controller. DNS is configured on dc1.
We have one exchange 2003 (SP2) server join the above domain.

I feel that the problem is occuring after we migrated from Ex2000 (dc2 - previously beside additional domain controller was also acting as an Ex2000 server) to Ex2003 on the new server.

However if i refres and reload the DNS on dc1 the problem gets rectified and will not generate for next 5 - 6 hours but sometime it may generate after 2 hours,, we cant predict at all.

Please let me know what causing the problem
