|0 cannot be added to the group |1.  This may be because SharePoint is being installed on a domain controller which does not allow some account types to be added to domain groups.  Administrators and Network Service will be explicitly granted access to all SharePoint resources on the local system.  You may need to manually grant other accounts the same access.
