I cannot connect to the internet. Network and Connection Sharing shows my home network and an Unidentified network and both are local only. This started on my other computer with a Realtek network adapter (can't remember the model). After 2 updates last night, my computer (different) showed the same problem on boot this morning. The updates were Definition Update for Windows Defender - KB915597 (Definition 1.57.1094.0) and Microsoft driver update for HP Photosmart 3200 series Installation status: Failed Error details: Code 80070490 I restored it to before these updates with no change. The only way that I can connect is to uninstall the NIC and scan for hardware changes (works on both machines). This NIC is NVIDIA nForce Network Controller. Both are onboard. I don't know if this is important but we have the HP Photosmart 3210xi printer on the network using it's own network adapter. Shutting the printer down did not change the situation. Searching shows this as a problem in Vista with no solution. I have tried everything that I have read from the Vista forums to no avail. I have used MS drivers and the latest manufactorer drivers. I have disabled public networks and IPv6. My router (Netgear) is configured correctly and I have assigned static IPs to both machines on both ends. I do have 2 switches on the network but they are just dumb switches. Any ideas?
