Windows 10: One PC out of 3 Can't See Others on the Network

Running Win10 on 3 PCs - call them X, Y, and Z. Both X and Y are running Win10 1709. Z very recently updated to 1803 but the networking issues started well before that update. I was hoping that 1803 would fix the networking problems, but no progress was made.

Here's the networking issue: X, Y and Z used to see each other and share files just fine. Two or three months ago Z stopped being able to see X and Y. They do not show up in Z's network at all. But X and Y can see Z just fine and can read and write files on Z. X and Y can also see each other and share files. So Z is the only one that can't see any other PCs on the network.

There is a shared printer connected to X via USB. Z can print on that printer even though the host X seems invisible. Maybe printer sharing is a totally different mechanism.

I have tried many different file sharing options on Z with no success. I use X and Y's network sharing setups as models for Z. The network fixers don't fix anything.

SMB 1.0 Status: X and Y have SMB 1.0 fully enabled. The three items are Automatic Removal, Client, and Server. However, Z has only two of the three items enabled. Client is disabled. I tried enabling Client but it remained disabled after the required restart. I have read a lot about the evils of SMB 1.0 but removing it from PC X caused it to not see any PCs on the network (not even itself) so I enabled it again.

Kind of at a loss as to what to try next. The situation is not dire since X and Y can access Z just fine so I can get files where they need to be. But Z really should be able to see and access the other two PCs.

Suggestions? Yeah I know I didn't provide much to go on.

PS: A really long time ago all 3 PCs used Homegroup for sharing but that stopped working so long ago I can't remember when. So long ago I switched to the non-Homegroup sharing which worked fine until recently.

Windows 10 PC can't see other PCs on network

Just a follow up on this,

In the office today on the domain, and I can confirm that this problem exists here too, - I can't see any other network PCS... so the homegroup/domain thing was a red herring...

I simply can't see other networked pcs..

 

Windows 10: Can see current wireless network, not seeing others

My Windows 10 laptop is working fine. It is seeing 9 available networks. It is sitting right next to my Windows 10 desktop PC which is seeing 2 available networks: the one it's connected to and "xfinitywifi". (Comcast is my IP, so no surprise there.) I can't
figure out why my desktop isn't seeing those other 7 networks. I know it did a while back but I can't say when it stopped seeing them.

I ran all the steps in this article without any luck: http://windows.microsoft.com/en-us/windows-10/fix-network-connection-issues

Can you get my desktop to see all available networks again? Thanks in advance for your help!
