Greetings: My computer was operating with Windows 7 Pro upgraded from Windows Vista. For many troubling reasons, I decided to do a reinstall. I started with Vista and it was reinstalled and I attempted to access the internet to see if all was well before I went to stage 2 to install Windows 7 Pro and I was denied with the following; "The Network Adapter Realtek RTL8101 Family PCI-E Fast Ethernet NIC (NDIS 6.0 is experiencing driver or hardware related issues. Click here for information and then This Driver Cannot Start Code 10. After I got that message, I check my device manager to determine if the driver was installed at all and it was and upon checking that, it told me that I had the best device driver for the computer and it is up to date. So, right now I am stuck.
