Following are steps needed to have earthworm (EW) start up automatically when a PC running Windows NT Workstation 4.0 boots up.

Overview of the steps

  1. Create new user 'earthworm'
  2. Setup the PC so that it automatically logs in as 'earthworm' upon reboot
  3. Setup EW so that it starts up every time user 'earthworm' logs in

Note: Selecting menu choices is denoted as follows:


This would mean that the Start menu is to be selected first, then Programs, etc.


(1) Create new user earthworm

(a) Click on Start->Programs->Administrative Tools->User Manager

  • User manager window should come up

(b) Click on User->New User

  • New user window should come up.

(b) Registry editor window should open. Click the Window titled


(c) HKEY_LOCAL_MACHINE window should come to the foreground. Double click on

the following:


(d) Now we need to create and/or set some values in the registry in the right

hand section of the window.

  1. AutoAdminLogon

If the AutoAdminLogon exits:

  • Double click on the AutoAdminLogon field. Enter 1 in the

pop up window.

If the AutoAdminLogon does not exit:

  • From the EDIT pull down menu, choose AddValue. In the pop up window, enter "AutoAdminLogon" in the ValueName box. Choose 'REG_SZ' for the data type. Click OK. Enter 1 in the next pop up window; then click OK.
  1. DefaultUserName

Click on Edit->Add Value. A dialog box should come up. Fill in:

Value Name: DefaultUserName click OK, another window comes up. Fill in: String: earthworm

Click OK.

  1. DefaultPassword
    • Follow the step above to add another value:

Value Name: DefaultPassword String: earthworm

When all is said and done, the following values whould be listed in

the right hand window:

DefaultUserName earthworm DefaultPassword earthworm AutoAdminLogon 1

(e) Click on Registry->Exit

(3) Automatic Earthworm Startup during login

(a) Restart the PC. If everything in step 1 and 2 was done correctly, the PC will automatically log you in as earthworm. (b) Make sure that the EW automatic startup script exists -- it should be called something like c:\earthworm\run\params\autostart_ew_nt.cmd.

Example autostart_ew_nt.cmd:

call ew_nt.cmd
call startstop.exe

(c) Click on Start->Settings->Taskbar

Taskbar window should come up. Click on the "Start Menu Programs" tab.

Click on "Advanced". NT Explorer should come up.

(d) By double clicking on the appropriate directories, find:


The right hand side window under Startup should be empty.

(e) Create a shortcut to the EW automatic startup script: In the right hand side window, click the right button, then select New->Shortcut.

A new window should come up, in the box enter the full path to the autostart_ew_nt script, click NEXT, and then click FINISH. OR click on Browse to select the path to the script using NT Explorer, highlight the autorestart_ew_nt.cmd, click OPEN, then NEXT, and then click FINISH. Last. then click OK in the TaskBar? window.


  • user earthworm must have a password in order for automatic login to work. This means that password cannot be blank.
  • make sure that when creating user earthworm it is added to all groups, particularly the administrator group, since earthworm will be the only user that can log in once the registry is changed.


Whenever a new version of Earthworm is installed, or a new configuration directory is desired, the autostart script must be updated. Basically, the file autostart_ew_nt.cmd mentioned above consists of the main command file ew_nt.cmd which is located in the params directory of the current configuration), with the addition of the startstop command which starts earthworm automatically. Therefore, whenever ANY changes are made to the local of the active ew_nt.cmd, the autostart_ew_nt.cmd file should be update.
