Getting Event ID 11 KDC error duplicate cifs names

Getting these events going back to August 2008 on a DC. When I do a search in AD on just the Domain, only one object shows up. When I repeat the search selecting Entire Directory instead of just the Domain, two objects show up. We have multiple Domains. On the second search, the duplicate object that shows up doesn't look right. It has no description and when I click on it, I get a popup saying "a referral was returned from the server". Then the properties are display but there is no information on any of the tabs.
My question is can I just delete this object using ADUC or ADSIEdit without causing any issues with the valid object?

I think deleting the wrong entry should solve it .. as usual: "your mileage may vary..."

Yeah, I saw that article. I was still unsure. Just wondering if anyone had any first hand experience with this.

Yes, you nead to search LDAP for what computer/user accounts are having the conflicting SPN set and delete the extra one that isn't used. CIFS SPN is part of HOST SPN (normally only HOST is used), so make a search for */3088A to find both prefixes.
C:\>dsquery * -filter "(servicePrincipalName=*/3088A)" -attr name

Run following command to list what SPNs are set for accountname
C:\>setspn -L accountname

Run the following command to delete HOST/3088A from accountname:
C:\>setspn -D HOST/3088A accountname
