Our main PC(desktop) which is the one I'm using right now had a homegroup set up on it with two other PC's(1 desktop & 1 laptop) connected to it. Shortly after installing "Cumulative Update for Windows 10 Version 1511 for x64-based Systems (KB3118754)" (for the two desktop PC's), I noticed that Steam went offline and said "NO CONNECTION" at the bottom, although the internet itself was still working as I was able to visit websites and such. After restarting Steam and seeing that the probelm still wasn't fixed, I decided to just restart my PC since the majority of problems tend to be temporary and fix themselves upon restarting(from my experience anyways).
When my PC booted back up and I got to my desktop(on the Admin account), I checked Steam and saw that the problem was fixed. However, I then noticed that when I went to the Homegroup tab on the sidebar in "This PC," I was no longer being counted as being in or as the host of the homegroup, but instead it's giving me the option to join a homegroup but doesn't mention who set it up.
So I decided to open "Troubleshooting" and after using "Windows Network Diagnostics" for "Homegroup/Network" it came up with the below error:
And not sure if you need it but here's the first two tabs of the more detailed info on the problem.
I also checked the other two PC's, both of which are also now disconnected from the homegroup too, however only my main PC and the other desktop PC come up with the above mentioned error when running diagnostics. The laptop seems fine with the exception of being disconnected from the homegroup as well. Another thing to note is that the laptop is the only one that actually states the name of the PC which the homegroup originates from(my main PC). Also, when attempting to connect to the homegroup from the other desktop PC, it comes up with an error saying that the homegroup is no longer available on the network(not exact wording, but similar to that).
Things I've tried:
- Restart of the main PC.
- Restart of router.
- Windows Network Diagnostics
- Cmd command "netsh int ip reset" which I found while googling a solution to this problem.
- Joining the homegroup which is still recognized as a homegroup but somehow isn't available.
Having a homegroup is quite useful to us, especially when it comes to remote printing since only one of the PC's has a printer. Any solution besides a factory reset will be welcome, and hopefully I provided enough information but if not, just ask for more. Also, if you need to see the system specs of any or all of the PC's then I can provide them.
Update: I just now updated the laptop with the newest Windows update to see if diagnostics would come up with the missing protocols error on there too, but it didn't. However, the laptop has now stopped displaying the name of the PC that the homegroup originates from.
