Problem just cropped up in the past two or three days. I lost the ability to get online through Internet Exploreror and AOL software. The hardware manager showed some sort of issue with the ethernet adapter and indicated "device cannot start (code 10)".The system is a Dell Dimension 4400 hardwired to a Linksys wireless router which is fed froma Sprint 660 dsl modem. Wireless laptop on the same network has no problem. Since it was a fairly cheap experiment, I installed a replacement Netgear adapter. No change.The tech from Netgear confirmed the system pings as though it has internet accessand suspects some sort of error with Internet Explorer or in the operating system. I note that I can't open Norton 360 and the tray at the bottomof the desktop doesn't show the programs normally in my start menu.
