shared folders not accessible after HomeGroup removed

I have three computers, two of them connected directly to the router, one over WiFi. All three of them run the latest version of Win 10 built 1803 (build 17134.191) . Ever since I upgraded the computers to 1803 and HomeGroup was removed, I have been having problems with networking. Computer A can see computer B and C, but B and C cannot consistently see A (shared folders, shared printer) – sometimes they do, sometimes not. Rebooting does not help.

Please advise, thank you.

Computer A can see computer B and C, but B and C cannot consistently see A (shared folders, shared printer) – sometimes they do, sometimes not.

If you haven't already .... Check Windows Services for the following two services ...

Function Discovery Provider Host - Running and Startup Type set to Automatic Delay
Function Discovery Resource Publication - Running and Startup Type set to Automatic Delay

Is the computer that has the file share wired or wireless?

My apologies for the delayed answer – I was traveling. Thanks for all your replies.

The issue still persists. I had experimented with Function Discovery Provider and Function Discovery Resource before posting the question here as I read about this issue with 1803. I had no success setting them to Auto Delay.

@ DMGrier – the computer that is not discoverable has a wired connection.

@ Brink – I checked the tutorial and the subsequent discussion but found no answer to my problem. Just to remind everyone – the problematic computer is sometimes accessible (but more often it is not).

Thanks.

Can you ping it by name and IP?

i can ping it by IP. I cannot ping it by name.

Netbios is the problem run this on all pcs and look which one is the master browser NetBScanner - NetBIOS scanner

OK, I ran NETBScanner on all three machines. Computer A (the one that is not accessible, wired) is not the Master Browser, nor is Computer B (wired connection). Computer C, that is connected via WiFi (also our backup computer, not frequently used) is the Master Browser.

OK, how do I use this info ? :)

Sometimes just running NETBScanner can get things working again, but not always and now we know which PC is the Master Browser, which can be helpful :)

1. When say that C is not frequently used, do you mean it's not turned on all the time ?
2 Do you have SMBv1 installed on your PC's ?
