Question : RidManager test failed in DCdiag

On running dcdiag on one of our DCs recently, the RidManager test failed:

      Starting test: RidManager
         Warning: attribute rIdSetReferences missing from CN=DC,OU=Domain Co
ntrollers,DC=company,DC=com
         Could not get Rid set Reference :failed with 8481: The search failed to
 retrieve attributes from the database.

On checking the rIdSetReferences attribute for the DC in Adsi edit, I found it was blank, unlike other DC's that had entries similar to 'CN=RID Set,CN=DC2,OU=Domain Controllers,DC=company,DC=com'.

I then tried manually correcting the attribute in line with the entries for other DCs.  However, I received the following message:

The attribute cannot be modified because it is owned by the system.

How do I get around this or is there another way to correct this problem?

Thanks,

Peter
