Back-up EXEC Problem with duplicate names

[JORY]

Dearest,

I keep getting this error notification during my backups, i tried to delete the names, it still occures:

The KDC encountered duplicate nameswhile processing a Kerberos authentication request. The duplicate name is MSSQLSvc/SMESDC01.smes.lan:10296 (of type SSQLSvc/SMESDC01.smes.lan:10296). This may result in authentication failures or downgrades to NTLM. In order to prevent this from occuring remove the duplicate entries for MSSQLSvc/SMESDC01.smes.lan:10296 in Active Directory.

Annyone experienced this before? and got a step-to-step repport to fix it?

Many thanks for reading and thanks for the posseble solutions!
