I have 6 PC's all running Win10 Home. I didn't buy them all at the same time; bought a new one, couldn't get rid of the old one 'cause it still worked, and so on
. The latest addition is a Xidax gaming PC that I bought last month; the others I keep around for redundant backups, running screen savers, etc.
All has been working and networking fine until 2 days ago. When I went to do my daily backup to all other PC's from my main one (the new Xidax) it could not see the other PC's. It could see the 2 NAS's and the Surface3 Tablet (on wi-fi) but it could not see any of the other 5 PC's on ethernet. I checked the Network Discovery settings to see if something got accidentally changed; they were fine. I went to all of the other PC's and they were all seeing everyone else on the network, including the new Xidax. And, I could access the drives on the Xidax from any other PC.
I shut down my router and entire network, switches included, and all PC's. After letting everyone sit powered down for 10 mins, I started all back up. Still could not see any of the other PC's on the Xidax, but everyone else was doing fine.
Next I went to Xidax website and chatted with a tech. He gave me a link to 3 youtube videos explaining how to fix "Windows Network Discovery" issues. All 3 videos outlined the same steps: Start Window's "Services" and change the following to "Automatic" start, instead of "Manual":
-Function Discovery Provider Host
-Function Discovery Resource Publication
-UPnP Device Host
I did this process to the Xidax and rebooted, as instructed. All 3 videos said this would definitely fix the issue. It did not. I still could not see any of the other PC's from the Xidax.
Next I went to one of the other PC's, and performed the process in "Services" as outlined. After restarting the 4 services, that PC immediately showed up on the Xidax. So, I did the same to another PC; it did NOT show up on the Xidax. I rebooted everyone and still the Xidax is only showing itself and one other PC on the network.
This is very frustrating and raises more questions than I started with:
a) What caused the Xidax to stop seeing everyone else 2 days ago?
b) Is it an issue with my router? I opened up its Admin page and it shows everyone working fine.
c) Why did one PC pop up instantly after performing the process, and another one did not?
d) Why should I be having this issue at all? Did a Win10 update do this, or did one of my apps suddenly decide to do this?
If anyone has had similar issues, and you know what the real problem is, please advise! I am no expert, but I do have over 28 years of accumulative experience and trained instincts with PC's and Windows, and this one is stumping me.
