问题 You want to improve the TCP transmission speed of a Windows 2000 Server computer. You also want to remove an unused registry key. You use Regedt32 to edit the registry of the Windows 2000 Server. You insert a value in the registry named TCPWindowSize, and you remove the unused key. You restart the computer, but the computer stops responding before the logon screen appears.

You want to return the computer to its previous configuration. What should you do?
选项 A、Restart the computer in Safe Mode. Then restart the computer again.
B、Restart the computer by using the Recovery Console. Run the Fixboot c: command, and then run the Exit command.
C、Restart the computer by using the Recovery Console. Run the enable winlogon service_auto_start command, and then run the Exit command.
D、Restart the computer by using the last known good configuration.
答案D
解析 Explanation: There are a number of solutions to take when attempting to recover from an incorrectly edited registry. The first solution is to restart the computer using the Last Known Good Configuration. This will load the last hardware and registry configuration that was automatically saved by Windows 2000 on the last successful start up of Windows 2000. The second solution is to restore the registry from a System State Data backup if a recent one exists. In this scenario we can use the Last Known Good Configuration (LKGC) as there has been no successful logon after the fatal change of the registry key. Therefore the Last Known Good Configuration has not been overwritten.

Incorrect answers:
A: When the registry is damaged we will not be able to use Safe Mode as Safe Mode is a basic version of the operating system with only the basic drivers that are required to support the operating system. Unfortunately Safe Mode requires the registry.

B: We can use the fixboot command in the Recovery Console to repair a faulty boot sector. We cannot use it to repair the registry.

C: The Recovery Console can be used to enable or disable device drivers, but it cannot be used to repair the registry.
