Windows 10: Troubleshooting Computer discovery issue

I have a friend (really!) that wants to file share 2 Win10 ver. 1909 computers. Computer A sees Computer B and can/does share folders correctly. But Computer B can not see/connect to Computer A - command : \\computer A fails. I have try many suggestion regarding settings in: services, DNS, ipconfig, Win updates, Network discovery, etc. But I am look for additional troubleshooting tricks to resolve why computer B does not see computer A. We can ping successfully in both directions. Any suggestions would be appreciated!

Hello,

Thank you for posting your query on Microsoft Community.

We regret the inconvenience caused to you and We apologies for delay in responding.

This issue might occur due to incorrect settings. I would suggest you to follow the below methods and check if it helps.

For each of the machines experiencing this behavior, will you please perform the following:

Step 1: Ensure Network Discovery is enabled.

• Control Panel\Network and Internet\Network and Sharing Center\Advanced sharing settings
• For each Network Category (Public, Private, Domain) you wish to have the feature enabled, click the arrow to the right of the category to expand it, and select “Turn on network discovery” & check “Turn on automatic setup of network connected devices”

Step 2: Ensure that Network Discovery is allowed inbound in the Windows Firewall (in addition to any other firewall in use).

• [Windows Key + R] > Firewall.cpl
• Click “Allow an app or feature through Windows Firewall” in the left pane.
• In the Allowed apps and features scroll box, find “Network Discovery”.
• Make sure it is checked for all of the Network categories that you have enabled.

Step 3: Ensure the necessary services are started.

• [Windows Key + R] > Services.msc
• Base Filtering Engine(BFE)
• Computer Browser(Browser)
• DHCP Client(DHCP)
• DNS Client(DNSCache)
• Network Connection (NetMan)
• Network Location Awareness(NLASvc)
• Remote Procedure Call (RPC)(RPCSS)
• Server(LANManServer)
• SSDP Discovery (SSDPSrv)
• TCP/IP NetBIOS Helper (LMHosts)
• Workstation(LANManWorkstation)

Step 4: I would suggest you to run Home Group troubleshooter and see if that helps.

• Click Start and type troubleshooting in the search box.
• Select Troubleshooting.
• Select View all on the top left corner.
• Run HomeGroup troubleshooter.

Let us know the update after you try the above steps.

Thank you.

 

SSDP Discovery missing from Services.msc

Hi Expert,

Is there anyone could explain why the SSDP discovery service is missing from my WIN7 computer?

I am trying to turn on the network discovery, but it sees didn't work, then I following the Microsoft KB suggestions to start the below services:

• DNS Client
• Function Discovery Resource Publication
• SSDP Discovery
• UPnP Device Host

when I trying to start SSDP Discovery, I found the service is just missing from my computer, I got no idea about that.

I checked in HKLM\SYSTEM\CurrentControlset\Services\， no any key about the SSDP discovery service, then I export the KEY from one normal WIN7 PC, import to the one which got network discovery issue. But seems it's not working, I still cannot find the SSDP
Discovery service in services.msc.

I have google so many troubleshooting, none of them worked for me. Please suggest,thanks!
