What should I do if SSP cannot be deleted?

If you cannot delete your SSP on the Management Center page, you can try the following command:

Stsadm-O deletessp-title "<SSP Name>"-Force

 

If you want to delete a database related to the database, you can use the following command:

Stsadm-O deletessp-title "<SSP Name>"-force-deletedatabases

 

If a database associated with SSP is in a crash state (suspect, emergency) or the service is in a crash state, you can restart the SharePoint timer service first.
