Error: "Attempt to fetch password of a group managed service account failed." (error 6)

Friends:

My AD DS is throwing an error reading "An attempt to fetch the password of a group managed service account failed."  The name of the service account is msa; the computer that it references is my domain controller.  And it is reporting error 6, whatever that means.

Does anyone know what this is and how to fix it?
