New Win10 Machine Can Only See Two of Three Other Machines on Network

Question

I have a 3 machine Homegroup network consisting of one Win7 and two Win10's, and 1 network printer. All 3 machines can see everything on the other two machines and the printer.

All 3 machines, and the new machine, are on the same WiFi network.

I'm trying to add a new Win10 machine with no Homegroup access. So I have used Network Sharing to allow the new machine to access the other machines. The new machine can see the Win7 machine folders and the Shared Printer, and it can see one of the Win10 machines and its Shared Printer.

But no matter what I try, the new machine cannot see the other Win10 machine. I shared the C:/ and every folder all the way down to the folder I need to access, which is the WSTD folder under the UPS program.

I have also gone through and set the permissions to allow EVERYONE to have full control over everything.

I can however ping the target machine from the new machine and I can ping the new machine from the target machine. And the Firewalls are turned off on both machines.

The new machine also cannot see the Network Printer, even if I try to connect it using the IP address. But I can ping the printer with no problems.

Anyone have any idea what's going on here?

I'm stumped.

Hi ,

Welcome to our new Microsoft Q&A Platform.

>>I'm trying to add a new Win10 machine with no Homegroup access.

Could you please describe it in details?

>> All 3 machines can see everything on the other two machines and the printer. The new machine cannot see the other Win10 machine.

Based on my understanding, the new machine cannot browse other machines on Network like the following screenshot.

If so, please turn on Network discovery and File and printer sharing.

And turn off firewall and anti-virus programs.

Additionally, you may enable Function Discovery Resource Publication service running. Please perform these operations on all machines.

Best Regards,

Candy

I have the same problem. My Windows 10 Pro Laptop cannot see Win 7 PC on the same "private" network. Win 7 desktop is physically wired to the wifi router, while the Win 10 Pro Laptop is connected via Wifi. After a lot of fiddling with the Network Sharing settings to make the settings on both machines similar did not do me any good. However, Unchecking the "USE 128-bit encryption..." from the Win 10 Pro side did the trick. Hope this information can be of some value.
