Not sure what it is. The server is running Server 2012 R2 and it is a VM. It has exchange and associated necessary features, roles, and prerequisites and nothing else installed. I have uninstalled and reinstalled Exchange 2013 CU7 3 times and each time this error has been present. It happens twice at boot and seems to cause no problems.
