Ok, I recently did a Win7 -> Win10 upgrade. There were some issues, as the install didn't complete, causing all sorts of chaos.

I seem to have most of it resolved. Did a restore, downloaded the most recent Windows update and installed, and more to get it mostly functioning again.

One strange problem persists. The computer is on a domain, and the network is called business.local. But, on this PC, it shows just as "Ethernet Connected". I can access the internet and go to sites, but every time I do, it says "your connection is not private". Chrome outright blocks me from most sites. On Edge, I can usually select to go to the site anyway. I can't run Windows Update (can't reach update service), and lots of other small issues.

I've tried updating the network adapter driver.
I've tried uninstalling it and restarting Windows.
I've tried changing DNS setting to 8.8.8.8.
I've tried taking it off the domain and putting it back on (and testing in between)
I've tried removing the one Windows Update that had been applied.
I tried a USB Ethernet adapter, in case something was bad with the internal card.
I totally took down the firewall.

Then, I ran the incoming connections troubleshooter and it says "More than one device is performing network address translation". But, all googling I do, the issue seems to come from using a second router or something in a private network. Since this one is on a domain, we only have one router doing NAT, so I have no idea why it's coming up with this (and every other PC on our network doesn't have this issue either).

Nothing seems to work. Network sometimes shows as "Unidentified" and sometimes as Ethernet Connected.

Any suggestions? I'd really appreciate some new eyes on this.

first of all, make backups of your files in the computer.

1 -is Kaspersky antivirus installed ?
the 2020 version is very bad. i had those kinds of problems randomly.
uninstall any antivirus or security software for troubleshooting for now

2 - make sur only one network interface is active.
command ncpa.cpl -> desactivate wifi if you use Ethernet cable and vice-versa

3 - reset the network stack
launch a command prompt in administrator mode and use this :
netsh winsock reset

4 - if everything fails, reinstall windows. Like another person said, it's best to activate windows before reinstalling.

So with the disclaimer that for the following post I am wearing my tin foil hat.

Since this is a company network could they be using a firewall feature that is spoofing a certificate server. This is the method than some commercial firewalls have that allow interception and decoding of HTTPS traffic. Normally in addition to the firewall software they push a update to the clients that add this fake certificate server into the list of trusted servers to avoid the alerts in the browser.

I know the company I worked for before I retired discussed but never actually implemented this.

So, nothing I could find to try seemed to have any impact...

Ultimately, I decided to back up the user's data, wipe the drive, and do a clean install...

And it worked.

I will never know what was causing that issue, but it's gone. Now to spend the entire day reloading all the software... Ugh.

Thanks for trying everyone. I appreciate it!
