I'm running into the DS_SERVICE_PRINCIPAL_NAME KDC Event 11 and I would appreciate some expert help resolving it.
I'm running a server 2003 domain. The host in question is server 2003 and running one instance of SQL 2005 and another of SQL 2000 and the error applies to the common SQL account that runs both instances.

I tried using methods 1 and 3 outlined at http://support.microsoft.com/kb/321044. I have to admit I'm not familiar with these tools or how to use the results. I tried using both ports 389 or 3268.  The exact error is MSSQLSvc/Host.Domain.org:1433 of type DS_SERVICE_PRINCIPAL_NAME.

Searching MSSQLSvc/MyServer.Domain.org:1433 returns a ton of results, from several servers and varied port numbers.

The SPN shall be unique and only exist on one single account, in this case the service account running SQL Server on MyServer.
Use setspn and remove the duplicated SPN from the accounts that shall not have the SPN

setspn -D MSSQLSvc/MyServer.Domain.Org:1433 accountname

The method I prefer is to use dsquery (similar to ldifde method) is to use dsquery.
dsquery * -filter (serviceprincipalname=<serchedSPN>) -attr name
dsquery * -filter (serviceprincipalname=<serchedSPN>) -attr name serviceprincipalname
