Description
By default, vCenter Server grants full administrative rights to the local administrator's account, which can be accessed by domain administrators. Separation of duties dictates that full vCenter Administrative rights should be granted only to those administrators who are required to have it. This privilege should not be granted to any group whose membership is not strictly controlled. Therefore, administrative rights should be removed from the local Windows server to users who are not vCenter administrators.
