9. Automatic Logon to Windows NT

Since the Model DSB2 OPtima PC has no built-in keyboard functions, it is shipped
from the factory with the Windows NT AutoLogon feature enabled. This has been
accomplished by setting a username and password (under Start/Programs/Ad-
ministrative Tools/User Manager) and matching that password with the
DefaultPassword in the system registry (see below). For shipment the powerup
user is “Administrator” and the DefaultPassword is “password.”

9.1 Disabling AutoLogon

Note that for the DSB2, if autologon is to be disabled a keyboard will be required
(for the CTL-ALT-DEL poweron sequence and to enter a user name and pass-
word). To disable the autologon function, enter a “0” (zero) for AutoAdminLogon
(using the registry editor as described below).

9.2 Bypassing AutoLogon

To bypass the autologon process (and logon as a different user), hold down the
SHIFT key after a logoff or after a Windows NT restart.

9.3 Changing the Username and Password

Go to the User Manager (under Start/Programs/Administrative Tools) and add a
user name and password. Then go to the registry editor (as described below).
Enter that user name and password as the DefaultUserName and
DefaultPassword, respectively. Set the AutoAdminLogon to 1 and save the
changes. Now the system will logon automatically using the new user name and

9.4 Using the Registry Editor

Caution: Using the Registry Editor incorrectly can cause serious, system-wide
problems that may require you to reinstall Windows NT in order to correct them.
Any problems that result may not be able to be resolved. USE THIS TOOL AT

Note that the entries described here have already been made for the DSB2.

1. Go to Start/Run. Type in REGEDT32.EXE and click OK.

2. Find HKEY_LOCALMACHINE\SOFTWARE\Microsoft\Windows NT\Current

3. From the Edit menu, choose Add Value. In the value name field, type
“AutoAdminLogon” (without the quotes). Set the data type to REG_SZ and click
OK. Enter a 1 in the string field for the new value name. Save the changes.

4. The following values should be assigned:
DefaultDomain Name



These values should be set to the values you would use when logging on.

5. If the DefaultPassword does not exist, one must be created. From the Edit
menu, choose Add Value. In the value name field, type “DefaultPassword” (with-
out the quotes). Set the data type to REG_SZ and click OK. Set the password to
that of the user shown in the DefaultUserName. Save the changes.

Note that a default password must be provided. If the DefaultPassword is left
blank, AutoAdminLogon will be set to zero when NT powers up (and autologon
will not occur).
