I had to reformat a Dell Latitude D830 with XP Pro SP2 due to a trojan.  After XP was reinstalled, I inserted the cds which contain the drivers and such for my system.  I installed the drivers and utilities, but for some reason when I plug my ethernet cable into the laptop, it says there is "Little or No Connectivity".  I plugged the same ethernet cord into the desktop I am currently using, and it works just fine.  The connection comes straight from the wall to the computer with no router or modem involved.  Can someone please help?  Thanks in advance!
