The server is running Windows Server 2008 R2, Enterprise and is a domain controller.

I have read on previous posts that this is due to an invalid certificate and more IIS related, only being a Windows domain controller, we don't have IIS on this machine currently.

Does anyone know what (else) it could be that's causing this?

Is 1F678132-5938-4686-9FDC-C8FF68F15C85 not reference to a Component Service? If so, which one would it be?

SB.
