Windows 7 x64 - Event ID 5060 from source NETwNs64

I'm having problems with a Intel(R) Centrino(R) Advanced-N 6200 AGN

I have the latest drivers available, using RADIUS authentication.

When logging on, network drives aren't being mapped.

I am seeing this in the event log:

The description for Event ID 5060 from source NETwNs64 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:

\Device\NDMP4

Intel(R) Centrino(R) Advanced-N 6200 AGN

The specified resource type cannot be found in the image file

Does anyone know what it means?

How can I fix it?
