how to setup autologon 2008 in a domain


Once you join a server to a domain, Windows will automatically delete the AutoAdminLogon value from the HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon registry key. This causes the userpasswords2 control to hide the “Users must enter a user name and password to use this computer” check box shown above.

Here’s how to get the missing checkbox back and configure Autologon:

  • Open a CMD prompt and enter the following (all on one line):
reg add “HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon” /v AutoAdminLogon /t REG_SZ /d “1” /f

  • Click StartRun and enter control userpasswords2
  • Clear the checkbox for Users must enter a user name and password to use this computer and click OK
  • Enter the user name and password that will be used for Autologon and click OK
