Windows 10 Try as I may, I cannot see a certain computer from another on my home network

[FireMarshalBill69]

I have a PC running Windows running Windows 10 ver. 22H2 and a laptop running the same, except for a minor variation in the build, on my home network. Both have an OS partition and a Data partition. I want to access the Data partition of the other from each machine, but cannot. I am able to see and map to the laptop from the PC, but am unable to see ot map to the PC. I can see the laptop from the PC and copy and move files to it and even back to the PC, but all from the PC. Of course, I can ping each computer from the other. I have turned on File and printer sharing on both and made the relevant folders shared on both machines.I have also set the Function Discovery Provider Host, Function Discovery Resource Publication and UPnP Device Host to Automatic. I am able to use my comparison software to copy files back and forth. I also am able to use Microsoft Garage mouse software to control; both machines with one keyboard and mouse. I have turned off all firewalls on both machines. I have even turned off IP6 for the adapter on both machines. Oddly, I can access the PC's Public folder from the laptop but not the drive and folders I need. But, I still do not see the PC in the laptop's Network to be able to access it. I am using the same network over wired Ethernet.
Any ideas? Totally puzzled! TIA.

To troubleshoot the issue where you are unable to access the Data partition of your PC from your laptop on the same network, follow these steps:

On the PC (Source Machine)​

1. Check Network Discovery:
   • Ensure network discovery is turned on to allow your PC to be visible to other devices on the network.
   []Verify File Sharing:
   • Confirm that file and printer sharing is enabled and that the folders you want to share have the appropriate sharing permissions.
   []Re-Share the Data Partition:
   • Adjust the sharing settings for the specific Data partition, ensuring that it is correctly shared on the network.
   []Configure Advanced Sharing Settings:
   • Open the Control Panel, go to Network and Sharing Center > Advanced Sharing Settings and enable network discovery and file sharing for private networks.

     On the Laptop (Target Machine)​

   []Check Network Connectivity:
   • Make sure your laptop is connected to the same network and can see other devices on the network.
   []Check Workgroup Configuration:
   • Ensure that both your PC and laptop are part of the same workgroup to facilitate easier network sharing.
   []Map the Drive:
   • Manually map the drive on your laptop by entering the network path (e.g., \PCName\DataPartition) to access the shared Data partition.
   []Windows Credential Manager:
   • If prompted for credentials, enter the username and password associated with the PC to establish the connection.
   []Firewall Settings:
   • Temporarily disable the firewall on your laptop to see if it is blocking the network access. If you can access the PC after disabling the firewall, adjust the firewall settings accordingly.

     Additional Steps​

   []Restart Both Machines:
   • Reboot both the PC and the laptop to refresh the network connections.
   []Network Troubleshooter:
   • Use the Windows Network Troubleshooter to diagnose and resolve network-related issues automatically.
2. Use IP Addresses:
   • Try connecting by using the IP address of the PC instead of the hostname to rule out any DNS-related issues. By following these recommendations and steps on both your PC and laptop, you should be able to access the Data partition from your PC on your laptop seamlessly.
