KDC, EVENT ID: 11 - There are multiple accounts with name MSSQLSvc/DELL700.<domain>.com:1433

I'm receiving the following message on my two domain controllers, in Event Viewer, 'System'
I've done some digging but I'm not sure how to correct this so the error won't appear any longer.  I have several things going on with this domain and I think this is just the beginning.  I appreciate any assistance you are able to provide.

You've propably installed MSSQL to first run with system rights causing the computer account to get the SPN set, and later changed to a service account.

The KB posted above describes howto find the duplicates.
You can also use dsquery command (part of adminpak.msi)

C:\>dsquery * -filter "(serviceprincipalname=MSSQLSvc/DELL700.<domain>.com:1433)" -attr samaccountname

When you've found the accounts causing the duplicate, use setspn command line tool to delete the SPN from the account that shall not be used

C:\>setspn -D MSSQLSvc/DELL700.<domain>.com:1433 <accountname>
One of the methods here http://support.microsoft.com/kb/321044 should get you started at least.
