Attempting to simplify question here. My network connections on a Windows 7 machine are hosed. Here are the symptoms:
- In spite of being a member of HOME homegroup, other computers on LAN do not see PC. However, the PC can see other computers on HOME.
- security video server (Blue Iris), not visible from LAN or WAN (using port forwarding on Netgear R6220)
- Logitech Media Server running on PC no longer visible by others on LAN.
I have uninstalled all software installed since the problem started and then used System Restore to restore back to what I think was a stable point. Also ran
sfc /scannow and found nothing.
Is there a way to fix the network stack without having to re-install the OS?
