Ethernet driver is installed!

The site you sent me to was the right one. I had downloaded the file 51782 and saved it on a flash drive. Then took the flashdrive to the other computer with the missing ethernet driver and tried to run it. No luck. So I downloaded the file to the desktop and then copied it to a flashdrive. Took the flashdrive to the other computer and copied the file from the flah drive to the desk top and ran it from the desk top and it worked! Thanks for all your help!
