I am trying to help a friend who moved her apps, etc. from an older Windows XP Pro computer to a brand new Windows 7 Home Premium PC. This was done via the ethernet ports through a router. After the transfer completed and the Windows 7 PC rebooted, the network card no longer works.
I tried the Windows 7 network troubleshooter - it agrees there is a problem, but has no clue what it is. Tells me it is a driver issue, but it is the driver from the factory that was working. Copied the driver files from a brand new identical PC just in case, no change.
I tried to delete the card and reboot, it found the adapter and initialized it, but no network.
Tried the netsh winsock reset - no luck.
Tried ipconfig release / renew - no luck
I am out of ideas. Does anyone know how to completely remove the Windows 7 networking crap under the hood so that it can re-build it from scratch? If not I am going to have to nuke the new PC back to the factory config and try it again.
