My Realtek 8111B onboard NIC was working fine for over a month. I tried to install Outpost Firewall and it froze during setup while installing some sort of network monitoring drivers. So I did a ctrl-alt-del to end the installation process.
After that happened, my NIC and other network drivers like the WAN miniport drivers have exclamation marks on them in the device manager.
The error that I see is code 31 and it says "Could not find the file specified".
I'm afraid I may have corrupted my NIC drivers because of stopping the Firewall installation midway. I've tried to reinstall the driver manually many times and that doesn't work. When I look at the driver details it shows the driver file is installed in C:\Windows\System32\ and I checked that the file was actually there, but it still comes up with the ""Could not find the file specified" error
And for some reason I can't uninstall the WAN miniport drivers, there is about 5 of them, they say IPv6, PPoE, etc... When I uninstall them, device manager refreshes but they are still there.
I also have another version of Windows on dual boot that also uses the same Vista x64 Realtek drivers and it works fine, so I don't think the NIC has a physical problem.
I didn't do any backups recently and don't have System Restore available.
Anyone have suggestions how I can solve this without having to do a clean install?
