Q: Which 3 rights are required for the vCenter Server service domain user account?

A:A VMware vCenter Server 5.0 instance relies on either a Windows domain user account or a built-in SYSTEM account for certain activities. When an ActiveDirectory domain user account is used, that account must be granted three rights on the vCenter Server. It must be a member of the Administrators group, and it must have the permissions Act as part of the operating system and Log on as a service. Note that the vCenter Server installer grants the Log on as a service right automatically as part of the installation.
