I'm having the same problem om 2 servers.

The servers has been running fine before for several months.

Win Server 2012 standard ( the other one is a Win Server 2008 R2 standard)

and SQL Server 2012 Standard

The VMWare Hotplug fix did not solve the problem.

Getting error messages about "access denied"

The local service accounts are in the sysadmin role.

Adding them to the local administrators Group solves the problem

but it is not best practices.
