Backup Exec 2010 - KDC duplicate name error

Medirex
Not applicable

‎07-15-2010 09:35 AM

I have Backup Exec 2010 installed on SBS 2008 w/ SP2.  When a backup job runs i get the following error:

The KDC encountered duplicate names while processing a Kerberos authentication request. The duplicate name is MSSQLSvc/ODIN.xxxxxxxxxx.lan:43429 (of type SSQLSvc/ODIN.xxxxxxxxx.lan:43429). This may result in authentication failures or downgrades to NTLM. In order to prevent this from occuring remove the duplicate entries for MSSQLSvc/ODIN.medirexsys.lan:43429 in Active Directory.


I can't find this entry in AD, nor do I really know where to look in AD for this.  Anyone know where to start?

I had this problem last year and it took me a while to resolve the problem.  Looking for the duplicate entry is quite complicated and editing the AD is even worse than editing the registry.  Search the Net for duplicate AD names/entries and there should be "how to" instructions.  Good luck!
