My friend just recently bought a new Toshiba Laptop. The operating system in it is Windows 7. I am trying to connect that system to my network so that I can install latest updates in it. But it does not looks to be working. The system is not able to identify my network. I am trying to connect a USB modem which fails to work. I checked in the error log and found the problem is related to some network configuration.cab file. How to fix this things.
