You are preparing for an upgrade of Windows 2000 Professional using Remote Installation Services （RIS） on a member server， which is in the Installation organizational unit （OU）. You loaded the RIS software and all images for the Windows 2000 Professional computer types into a shared NTFS version 5 volume.   You distributed a remote installation boot disk to all users in case their adapter doesn’t support PXE boot ROM and doesn’t have BIOS support for using the PXE boot ROM as the primary boot device. The users report that they are unable to install Windows 2000 Professional.  What do you need to do in order to resolve the problem？（）

• A、 Include the users who will do the install in the Installation OU where the RIS server object is located. Assign them rights to "Bypass traverse checking." 
• B、Load the Windows 2000 Professional images onto the server's boot drive, which is a  separate hard disk from the RIS software. 
• C、Create a security group for the users who will do the installation and assign the group "Log on  as a batch job" rights. Assign the group permission to create computer accounts. 
• D、Reinstall the RIS software on a domain controller in a shared volume and modify the boot  disks to map to the shared volume.
