Have tried uninstalling and letting win reinstall drivers... no good effect. Used Nvidia nforce drivers -- no effect. Device manager adds host controller with an increased number "Nvidia network host controller #4, #5, #6, etc" . I have had this problem once before, but don't remember what the fix was. I recall it was something fairly simple.

network adapter is still not operable. Any ideas.

Cheers

Just as a test I would use another machine and get any linux "Live" cd ubuntu is a good example. Then boot the machine from CD and it will attempt to allow connectivity to the web. If that works its another microsoft enhancement

click start
click run
type sysdm.cpl
hit enter
click the hardware tab
then device manager
uninstall ur network card
then make sure your name of your pc is highlighted at the top of the list
click action
scan for changes
