As the administrator of your Windows 2000 corporate network you need to install Windows 2000 Professional on 88 computers, and you would like to do it with the least amount of administrative effort. 
You have 38 PXE-Compliant computers and 50 NON PXE-Compliant computers ready to go. You confirm that all 88 computers and their hardware are included on the current Windows 2000 hardware compatibility list (HCL).You create an RIS image and load it onto a Windows 2000 RIS Server. You then start the 88 computers. You find that the 38 PXE-Compliant computers connect fine to the RIS server, however the 50 NON PXE-Compliant computers cannot connect to the RIS server. 
What should you do to resolve this problem?（）

You are the administrator of Red Lington Enterprises. You want to upgrade 125 computers from Windows NT Workstation 4.0 to Windows 2000 Professional. You create an unattend.txt file by using the setup manager. 
You copy the file to a floppy disk. You then start the installation on a computer in the test lab using the Windows 2000 Professional CD-ROM.  After the computer starts you insert the floppy disk. Even though you set the user interaction level to full-unattended mode you are prompted for all the configuration parameters. You want to ensure that the unattended installation does not prompt you for input. 
What should you do？ （）
