This device is not working properly because Windows cannot load the drivers required for this device. (Code 31)

No solution yet. :-(

It started all when I installed Windows 7. To get online when travelling I installed a driver for a UMTS stick and it all worked fine, but suddenly the connection could not be established (anymore!).

I tried a thousand things, but I am still stuck with this error. When I plug in the UMTS stick I get an error when installing the driver  - something with modem always.

Then I got a new mobile phone - Samsung Galaxy S plus and when I plug it, I get the same error. :-(

Kies cannot connect. :-(

Now I unstalled the device (without deleting the software. Let's see what happens.

Then I unplugged the device and let Kies install some driver. It does not say what exactly.

After plugging in the phone it has the same error when installing the driver:


Eventlog says this: "The description for Event ID 1 from source Modem cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer.

If the event originated on another computer, the display information had to be saved with the event.

The following information was included with the event:

\000000a4"

Update Jan 2012: I gave up and installed my whole Win 7 from scratch. Now it works again. I wonder what broke it and if it will happen again. :-(

How to delete WebSEAL servers which have not been configured correctly.

Problem: The WebSEAL server list in the pdadmin: pdadmin> server list shows the server, but it does not exist anymore, i.e. because the host has been disassembled without unconfiguring the WebSEAL instance. Solution: 1.) Delete the instance in the LDAP under: SecAuthority=Default - cn=securitygroup - cn=webseal-servers - cn=secmgrd-servers 2.) Configure the instance again, which will lead to an error, because it seems to be installed already.
