        My home system consists of four Windows Pro computers and three NAS (Drobo) drives plus external drives and printers and scanners.  Everything was working and every computer could see and access all the other computers and NAS drives.  Since today’s update of the last two computers to 1903, the network shows the following:  Every computer sees the “Marion”  computer and can access it.  None of the other computers can see any of the NAS drives nor any other computer nor even their own on the File Manager.  The NAS drives can still be acesses and files used if there is a pre-existing letter assignment to the device.  I know that all the computers and devices use SMB v1, and thus in all of them this feature is enabled.

        Any help would be gratefully accepted.

        Recheck the SMB on the updated computers and be sure the update did not turn it off.

        I checked the SMB 1.0/CIFS settings, and all the computers have the client and server checked.

        Since 1607, each Feature Update has gotten a bit more “flaky” on networking.

        Re-check and check these things to make sure that nothing has changed:

        1- Go to Control Panel from the Start menu and select Network and internet.

        Click on Network and sharing to select Change advance sharing settings from the left pane.

        Tick the options –

        Turn on network discovery.

        Turn on file and printer sharing.

        Allow windows to manage home group connection (recommended).

        Turn on sharing so anyone with network access can read and write files in the public folders.

        Use 128-bit encryption to help protect files sharing connections (recommended).

        Turn off password protected sharing.

        2- You checked SMB.1 BUT

        Scroll down to SMB 1.0 CIFS File Sharing Support and put a check mark on SMB 1.0/CIFS Client and SMB 1.0/ CIFS Server. If the boxes are already ticked, please uncheck the box and check it again.

        Reboot the machine when prompted.

        3- Also, make sure that the below mentioned services have setup the Startup type to Automatic in Services.msc for network sharing –

        Function Discovery Provider Host (FDPHost)

        Function Discovery Resource Publication (FDResPub)

        Network Connections (NetMan

        UPnP Device Host (UPnPHost)

        Peer Name Resolution Protocol (PNRPSvc)

        Peer Networking Grouping (P2PSvc)

        Peer Networking Identity Manager (P2PIMSvc)

        See if all that changes anything, if not, have you tried “Mapping Drives”? I’m on 1809 and that was the only way I could get all my drives recognized since they showed up some times and not other times.

        Hope this helps.

        Don't take yourself so seriously, no one else does 🙂

        Thank you for all the suggestions, but unfortunately none of them really helped.  In the meantime I used the steps for previous versions of Windows with the same problem (changing the SMB to version 1 in the “lanmanworkstation”), and that actually shows some of the other computers at some time, not at others.  I am able to connect and use files in all the computers from each and every other one.  This can be done by a previously mapped drive letter, by using the icon if the computer happens to show at the time, or always using the \\Computer Name approach.  The three NAS Drobos can also be accessed through the last method, but I still require them in the Windows Explorer listings of them which so far have not shown up at all.

        In the past, I had a problem connecting to my Modem Admin page from one computer on my local network, but otherwise had full internet and router access. The problem was Kaspersky Internet Security. I uninstalled and re-installed and all was restored to full operation.

        More recently, I had problem with network discovery on my local network after upgrading from Win 10 1803 to 1809. The problem was Bitdefender Internet Security. I uninstalled Bitdefender on all my computers, switching to Windows Defender. This fixed all the network discovery problems on my local network.

        My take away from this is:  For strange network problems, look to 3rd party A/V products.
