This apparently started happening after the OU in question was renamed. No one recalls a policy mapped to that OU nor does it appear to be affecting anything negatively. More troubling though, I can't seem to locate a policy anywhere that either matches that GUID or directly relates to that OU. How else can I track down what policy is throwing this error?
