The Windows 2000 Server CD-ROM is unavailable. You want install Windows 2000 Server from source files that are located on a server on the network. You also want the entire hard disk of the new computer to be used for the system partition.

E．Start the computer by using a Windows 98 network boot disk. Create and format a single FAT32 partition. Start the new computer by using a Windows 2000 Emergency Repair Disk.


正确答案：D
解析：Explanation: To install Windows 2000 Server on computers from source files that are located on a centralized network share we would have to connect to the network share from the the computers. If the computers do not have PXE-compliant network cards we would have to make a network boot disk that the computers can use connect to the network share. We would start the installation process by using winnt with /s /u /udf switches. We must use winnt and not winnt32 as the boot disks operate in DOS mode, which works with 16-bit applications. We would thus not be able to use 32-bit applications like winnt32.

Incorrect answers:
A: Makebt32 is used to create a set of four setup floppy disks.

B: The boot diskette must include network drivers.

C: Dsclient.exe is a directory service client for Windows 9x. It cannot be used to start an installation of Windows 2000.

E: The installation process cannot be started by using a Windows 2000 emergency repair disk.
