系統 - win2k advance server自動登入的方法

[psac]

WinNT自動登入的方法： 1、以本機域系統管理員帳號（Administrator）登入，然後在「RUN」表單中執行註冊表編輯指令：REGEDT32； 2、開啟「HEY_LOC_MACHINE」項下的Software\Microsoft\WindowsNT\currentVersion\WinLogon分選項； 3、選WinLogon，首先增加一設定自動登入的主鍵值，按下Edit表單下的「Add 類型…」，在彈出的對話視窗「類型 Name」下按鍵輸入「AutoadminLogon」鍵，在接下來的「DataType」中選取「REG-SZ」，然後輸入「1」，按OK返回； 4、用同樣的方法增加「DefaultUserName」和「DefaultPassword」兩個鍵值，分別在兩個鍵值中輸入相應的「預設值用戶名」和「預設值用戶帳號密碼」。注意有的時候安裝後系統就已原有的以上「DefaultUserName」鍵值，這樣就不必再另外增加了，只需雙按它對其修改成預設值的用戶名即可。另外，WIN2000和WINNT相同。

256986 Description of the Microsoft Windows Registry


SUMMARY
This article describes how to configure Windows to automate the logon process by storing your password and other pertinent information in the registry database. This feature allows other users to start your computer and use the account that you establish to automatically log on.

IMPORTANT: If you enable autologon, using Windows XP becomes more convenient. However, using this feature can pose a security risk.
MORE INFORMATION
WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

If you set a computer for automatic logon, anyone who can physically gain access to the computer can also gain access to everything that is on the computer, including any network or networks that the computer is connected to. In addition, if you enable automatic logon, the password is stored in the registry in plain text. The specific registry key that stores this value is remotely readable by the Authenticated Users group. As a result, using this setting is appropriate only if the computer is physically secured and if you ensure that untrusted users cannot remotely see the registry.

Use Registry Editor (Regedit.exe) to add your logon information:
Click Start, click Run, type regedit,and then click OK to start Registry Editor.
Locate the following registry key:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsNT\CurrentVersion\Winlogon


Using your account name and password, double-click the DefaultUserName entry, type your user name, and then click OK.
Double-click the DefaultPassword entry, type your password under the value data box, and then click OK.

If there is no DefaultPassword value, follow these steps to create the value:
On the Registry Editor menu, click Edit, click New, and then click String 類型.
Type DefaultPassword as the value name, and then press ENTER.
Double-click the newly created key, and then type your password in the 類型 Data box.
If no DefaultPassword string is specified, Windows automatically changes the value of the AutoAdminLogon key from 1 (true) to 0 (false) to disable the AutoAdminLogon feature.


Double-click the AutoAdminLogon entry, type 1 in the 類型 Data box, and then click OK.

If there is no AutoAdminLogon entry, follow these steps to create the entry:
On the Registry Editor menu, click Edit, click New, and then click String 類型.
Type AutoAdminLogon as the value name, and then press ENTER.
Double-click the newly created key, and then type 1 in the 類型 Data box.
Quit Registry Editor.
Click Start, click Restart, and then click OK.
After your computer restarts and Windows starts, you can log on automatically.
If you want to bypass the automatic logon to log on as a different user, hold down the SHIFT key after you log off or after Windows restarts. Note that this procedure applies only to the first logon. To enforce this setting for future logoffs, the administrator must set the following registry key:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsNT\CurrentVersion\Winlogon

類型:ForceAutoLogon
Type: REG_SZ
Data: 1

You can also use the following steps to enable automatic logon without editing the registry in Windows XP Home Edition and Windows XP Professional (not joined to a domain):
Click Start, and then click Run.
In the Open box, type control userpasswords2, and then click OK.
In the dialog box that appears, clear the Users must enter a user name and password to use this computer check box, and then click OK.
