How to get into your PC in emergency cases
In seldom cases, the ID Device login software
does not only prevent access of unwanted persons but also of the authorized
person itself. Typical reasons for such malfunctions are:
-
Installation errors, e.g., installing an outdated
software version such as 3.1 over a current version 5.x
-
Hardware defects (ID Mouse, disk drives, USB,
...)
-
Manipulations of important ID Device software
files
-
All fingers that have been registered are
temporarily hurt and cannot be used for authentication while the user has
chosen the option to access by fingerprint only.
In such cases it can be necessary to bypass
the biometric security functions to get access to the locally stored data.
It depends on the precautions of the user/administrator how time-consuming
bypassing is. Generally, trying to prevent bypassing to improve protection
also complicates emergency bypassing.
Note: This description
may also be used to estimate and to manage security items. The following
steps require good PC know-how!
Bypassing under Windows 98 and Me
First Method
Press F8 or CTRL (depends on your PC hardware)
permanently during booting to enter the "safe mode". It may be necessary
to enter the password now. In the safe mode, you may change the ID Mouse
settings using the user manager. If you want to deactivate the ID Device
software, rename the hidden file "cmnp.dll" to, e.g. "cmnp.dll---". cmnp.dll
is found in the directory <WINDOWS>\SYSTEM. After rebooting, an error
message appears. Click OK!
Second Method
If the safe mode has been deactivated, it
may help to use an emergency floppy disk to boot in MS-DOS mode. If you
are in the root directory C:, type (replace <WINDOWS> by the real name
of your windows directory, which normally is WINDOWS):
cd <WINDOWS>\SYSTEM
attrib -h cmnp.dll
ren cmnp.dll cmnp---.dll
If the command "attrib" does not work since
it is only available in the COMMAND directory, type
C:\<WINDOWS>\COMMAND\attrib
-h cmnp.dll
Now reboot your computer as in the first method.
If booting by floppy disk has been deactivated,
press the function key displayed during booting to enter the BIOS. There
you must reactivate booting by emergency diskette.
If the BIOS is password protected and the
password has been forgotten, contact your PC dealer how to manage this
situation (depends on the specific hardware).
Third Method
Booting from Windows CD, tbf.
Bypassing for Windows 2000 and XP
First Method
Press F8 or CTRL (depends on your PC hardware)
permanently during booting to enter the "safe mode". It is necessary to
enter the password. In the safe mode, you may change the ID Mouse settings
using the user manager. Furthermore, if you login as administrator, you
may uninstall the ID Mouse software to get normal access by User ID and
password.
Second Method
If booting from CD has not been deactivated,
try this procedure:
-
Insert Windows installation CD and boot from
CD
-
When the greeting window comes press F10 (even
if it is not offered). Do NOT press F3 or RETURN
-
Black screen: Choose installation of Windows,
e.g., "1".
-
Enter administrator password.
-
type (without quotation marks) "cd SYSTEM32"
-
type "ren IDGPOSLogin.dll IDLogin.dll"
-
type: "copy msgina.dll IDGPOSLogin.dll"
-
type "exit"
-
Reboot
Now the standard Windows login window should
appear instead of the ID Mouse login.
If booting by CD has been deactivated,
press the function key displayed during booting to enter the BIOS. There
you can reactivate booting by CD.
If the BIOS is password protected and the
password has been forgotten, contact your PC dealer how to manage this
situation (depends on the specific hardware).
Third Method
This method requires hardware knowledge and
is only recommended for experienced users!
-
Dismount the hard disk drive and assemble
it as additional drive in another PC with the same file system
-
Rename the file "IDGPOSLogin.dll" in the directory
SYSTEM32 to "IDLogin.dll"
-
Create a copy of "msgina.dll"
-
Rename this copy to "IDGPOSLogin.dll"
-
Remount the hard disk drive to the original
PC
-
Reboot
Now the standard Windows login window should
appear instead of the ID Mouse login. This method is to be applied when
the Administrator password has been lost and the Safe Mode does not work. |
