Windows 10: Suddenly can't see other computers on network

    A is playing games with me. Sometimes it will show one or the other of the two laptops. Then if I refresh, it might remove the computer it was just showing. However, now it does show itself consistently.

    Yes, the other two PC's can see and access each other (including the NAS) from File Explorer > Network. They can also access A in Network.

    For PC A ...
    1. Computer Browser Service is running and startup type set to Automatic ? YES It's set to Automatic (Trigger Start)
    2. You can still manually access the other PC's and NAS using File Explorer > Address Bar > \\PCNAME or \\IPADDRESS correct?

    [EDIT: I should record here that I was WRONG in what I wrote below--I was trying to use //PCNAME/ instead of \\PCNAME\]

    No, not at all. In fact, right now I can't even reach the PCNAME or IPADDRESS from any of the computers. Maybe I am doing something wrong. If I put this in the File Explorer Address bar, it usually kicks me over to my browser as a Google search. In the past, I believe this has worked from B or C, but not now. I can't make it happen from ANY of the computers. ...I wonder if this could have something to do with the Master Browser NOT being a Windows computer. There is a setting in the NAS, where I can ask it not to try to be the Master Browser.

    This was going to be a duplicate, because my previous did not appear at first.

    This is getting to be very tiresome. I'm sorry to bother you guys so much with this, but I am at the end of my rope.

    Are you forgetting the \\ by chance ?
    In File Explorer > Address Bar ... it has to be \\PCNAME or \\IPADDRESS
    PCNAME - the device name you're trying to access (e.g. \\MYDESKTOP-PC)
    IPADDRESS - the ip address of the device you're trying to access (e.g. \\192.168.1.2)

    I wonder if this could have something to do with the Master Browser NOT being a Windows computer. There is a setting in the NAS, where I can ask it not to try to be the Master Browser.
    I would not change it at this time. The NAS being the Master Browser should be OK (it's probably on 24/7) and will always maintain the list, where as you PC's are probably not on 24/7.

    Sorry for your frustration, I know this stuff can be a PITA ... hang in there

    SORRY, BIG ERROR!

    You're right, somehow I got my signals crossed, and was using // instead of \\.

    Okay, I did try letting the Windows computers decide the Master Browser, but I will go back and let the NAS do it.

    So, I can indeed find all the computers from Computer A by using \\PCNAME\SHARE. So the problem that remains is that "Network" does not show all of the computers, even after a long time of the machines being on. So this seems like some sort of DISPLAY issue. (Only on Computer A.)

    Yep, that's easy to do :)

    I have seen this before and it was the one or both of the two Function Discovery Services had stopped and needed restarting on the other PC's (B & C in your case). You can manually restart them and see if they show up on A. This might be an issue with their startup type set to Automatic vs Automatic Delay. As I mentioned before Automatic was problematic for me and set mine to Automatic Delay and haven't had any issues since. If you do change their startup type, remember to reboot and actually check Windows Services that they are running :)


    Note: I Don't think we missed anything, but I'll have to think about it a bit.

    Still no luck showing all the Network computers in Explorer/Network. However, at one point, after A had been running a while, I found it displayed almost all the computers, including the NAS, in the File Tree on the left, including the shares inside, but still would not display all these (only A itself) in the main window on the right side. How to account for such aberrant behavior??

    Short answer - Not really sure.
    Long answer - Turning the Master Browser off/on for the NAS and if one of the other PC's became the Master Browser, it's list might not be fully updated yet. It can take awhile (maybe 24hrs) for the Master Browser list to get all sorted out, but other than that I'm not sure.

    You've made a lot of changes and you probably just need to leave things be for awhile and see if it straightens itself out.

    If you really must try and solve this now .... I would ....
    1. Make sure the NAS is set to be the Master Browser
    2. Shut down ALL PC's (NOT REBOOT)
    3. Reboot your NAS and once it's up and running ... then start each PC one by one.

    Today I will be shutting down all the computers and starting them one by one, starting with the NAS. The NAS will be the Master Browser, and I will start that machine first.

    I was also interested in the idea of identifying the NAS in the hosts file of the problem machine. I am communicating on the web site of OpenMediaVault, the NAS software I am using, and flmaxey has a guide on how to do this. flmaxey also has a different idea about SMB and the 3 versions. I am wondering what you think of this:

    It looks like I am going to have to just live with this quirky behavior of Computer A, where it won't show all the network computers in the right panel. Sometimes it shows them in the left file list. I restarted all the computers, after adding the NAS to hosts file for Computer A, and this had no effect. I can get at the NAS from that computer via browsing to it in my backup program, so I guess I don't really need to have it shown in Explorer\Network. I'm about to update Laptop B to 1803--with some trepidation.

    Thanks a huge amount for your help! Maybe one day that A machine will catch up with the times and start showing the icons in Network!

    Just so I'm clear ...
    Under File Explorer > Network (left pane) the PC's it does list are missing from the right pane?

    Note: A screen shot of what you're seeing would probably help :)

    I'm about to update Laptop B to 1803--with some trepidation.
    Don't forget to check that SMBv1 is still installed and the appropriate services are running and their startup types are set :)
