Tips: "Windows NT 4.0 auto logon (both server and workstation)."

Problem: You have some kind of application that you have to run on the Windows NT desktop instead as service.

Cause: If the machine is rebooted the logon screen will appear and the application will not start until you manually log on the computer.

Solution: Do some changes in the registry like this:

Klick on "Start", choose "run", and type "regedit" (or "regedt32")
and klick on "OK".

Locate the Registry subkey:

HKEY_LOCAL_MACHINE
\SOFTWARE
   \Microsoft
    \WindowsNT
     \CurrentVersion
      \WinLogon

Verify that the "DefaultDomainName" and "DefaultUserName" exist and are using the values you would normally type when logging on. If some of them don't exist, choose Add value from the Edit menu. In the value field, type: "DefaultDomainName" or "DefaultUserName" .Select REG_SZ for the Data Type. In the string field, type the domainname or username. Save your changes.

If the "DefaultPassword" does'nt exist, choose Add value from the Edit menu. In the value field, type: "DefaultPassword". Select REG_SZ for the Data Type. In the string field, type the password for the user chosen above. Save your changes.

From the Edit menu, choose Add Value. Enter "AutoAdminLogon" in the Value Name field. Select REG_SZ for the Data Type. Enter "1" in the string field. Save your changes.

Exit Regedit, restart the computer and it should logon by itself.
