We are getting the following error " event ID 11 The KDC encountered duplicate names while processing a Kerberos authentication request" on our DC (see attached text file).  I've found the duplicate entry using "setspn -X" (see attached jpeg) however the duplicate entry is a user "Administrator" and not a computer.  I can use "setspn -D" to delete the entry but I'm unsure what the SPN and computer name would be.  I've never had to do this before and I don't know what the consequences are if I get it wrong. Can anyone help please.

Thank you in advance. MAGPIE-ERROR.txt Duplicate entry screenshot
