Somebody setup the SPN for the service account on those machines,
unfortunately the same SPN has been promoted more than one time.

The SPN should be registered under the account SQL is starting under, and
ONLY that account.
You can use the utility setspn to check for the existence of other spn's,
delete the ones you don't want, and add the one you need.
Please are NOT deleting the ACCOUNT, but the Service Principle
Name, which resides IN that user object.

Here's an article with more info than you ever wanted to know about SQL and
but there are links to getting setspn in there.
