How To Enable Automatic Logon in Windows 2000/XP Pro With a Domain System
A: To enable auto logon in Windows 2000/XP with a domain system, you need to edit the registry. Start Regedt32.exe and locate the following registry key: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon; Enter your domain name, account name, and password, using the following values : DefaultDomainName, DefaultUserName, and DefaultPassword. (NOTE: The DefaultDomainName and DefaultUserName values may already exist.) .
If the DefaultPassword value does not exist, create it. To do so: On the Edit menu, click Add Value; In the Value Name box, type DefaultPassword; In the Data Type box, click REG_SZ.; Click OK; In the String Editor box, type your password. Click OK and save your changes. (NOTE: If no DefaultPassword string is specified, Windows automatically changes the value of the AutoAdminLogon key from 1 (true) to 0 (false). This disables the AutoAdminLogon feature. This behavior also occurs if the DefaultPassword string is specified but the password is left blank or null.)
- On the Edit menu, click Add Value. Type AutoAdminLogon in the Value Name box. Click REG_SZ in the Data Type box. Enter 1 in the String box. Save your changes.
- Quit Regedt32.exe.
- Shut down Windows and turn off the computer.
- Restart your computer and Windows 2000. You should be able to log on automatically now.
