Network neighborhood in windows 10 disappears after Windows 10 update last week.

[Integraoligist]

I have a small office that all the PCs are hardwired and running Windows 10 Pro.
Everything has been running fine until last week, we come in and 1 of the PCs does not see any other PCs on the network. All the other PCs are working fine and see all the other PCs besides this one.

The only thing that happened from it working to not working was a Windows update that installed overnight. 2 actually, here they are:
KB4034674
KB4034662

I assume the issue is with KB4034674 as the other is just a Flash update. But I went ahead and uninstalled both, rebooted, and checked... well the PC shows up in Network now, but just this 1 PC, and no others. I checked the other PCs on the network and none of them see this PC yet.

I went ahead and reinstalled the newest updates... checked again, and the PC is gone again from the Network. 

Any ideas on what I can do? Whatever it did, even after uninstalling the updates I still can't see any other network PCs.

Typing the IP to the server PC is no problem, it shows up and there are no issues... we already have a Workgroup and not a Homegroup... We already have shortcuts to folders on the server from this station, any they are working fine... we just mapped a drive via the IP and it works... we also mapped the drive via the PC name, and it works as well... so we're able to get to the files on the server station from this PC.

The problem now is, the main Sales software that we use, it is still not recognizing the server. We contacted the software developer and they went through all their software and registry editing the navigation to the server which originally uses the servers PC name, we changed it to the IP... but it still will not see the server folder. They said because you can't see the PCs in network neighborhood the software will not navigate to the PC and because this is a Networking issue, they can't do anything else. 

Any ideas on how to fix this network neighborhood issue?

I checked the other PCs on the network, all ALL of them have these same updates... BUT none of them are having this issue... None of the other PCs are HP either... just this one we're having the issue with. I just installed HP Support Assistant to try and get the latest update and drivers... but it says we're already up to date with everything.
Thanks!

I have some basic tricks for you try these
1: Try reinstalling network driver.
Open device manager and expand network adapter then select update driver and reboot.
(If it doesn't work select remove device reboot then select update driver).

2: Open command prompt and type this command
Ipconfig/flushdns
3: Open Control Panel.
Tap or click Network and Sharing Center.
Tap or click Change adapter settings in the navigation pane.
Right click on Ethernet adapter and select disable then wait for 30 seconds then enable it again
Now check if your problem is fixed

I hope this helped you.

Hi, we already attempted all of these fixes but to no avail. The other PCs in the office are fine with those same updates, it looks like it's specific to this HP unit. The POS software is the only software on the system, as with all of our systems, so we know it's not something that we added causing the issue.

You need to contact HP support helpline for the support

Windows Network Neighborhood & Network Browsing have both been removed (deprecated) by Microsoft. They removed SMB version 1 since it was vulnerable to hacks (malware, etc). Please read this entire web page - especially the last paragraph titled "Explorer Network Browsing"
