event ID 11 There are multiple accounts with name MSSQLSvc/xxxxxx

I am seeing event ID 11 in event viewer for many servers (all sql servers) – windows 2003 Domain

There are multiple accounts with name MSSQLSvc/bq_sqlsrv.uk.corp.company.net:1433 of type DS_SERVICE_PRINCIPAL_NAME.

There are multiple accounts with name MSSQLSvc/dk_sqlsrv.uk.corp.company.net:1433 of type DS_SERVICE_PRINCIPAL_NAME.

There are multiple accounts with name MSSQLSvc/om_sqlsrv.uk.corp.company.net:1433 of type DS_SERVICE_PRINCIPAL_NAME.

So i had a read of this bloghttp://blog.joeware.net/2008/07/17/1407/ and ran his adfind tool which gives the below results.

1. I have many other sql servers in our estate that produce no errors and just have two SPN's ( HOST\netbious and HOST\fqdn) which i believe are the defaults  
2. But I am worried about deleting MSSQLSvc/DK_SQLSRV.uk.corp.company.net:1433 because i can’t find any information that says MSSQLSvc will map to HOST   
3. I can’t find MSSQLSvc/BQ_SQLSRV.uk.corp.company.net:1433
4.  All 3 servers have sql installed and running.
5. I have many other sql servers in our estate that produce no errors and just have two SPN's ( HOST\netbios and HOST\fqdn) which i believe are the defaults

So i am not really sure how to proceed
