@Rboppy
If you will give a brief explanation of what is happening between the 4 computers we can try to help with networking. Give as much info as you can.
Networking issues is different for different people.
Here are some of my notes regarding networking problems I have encountered along the way. By no means does it solve EVERY sharing problem, but when I mixed 10 and 11 in my network, I used these methods to solve the issues I encountered. These suggestions all came from other forum members, especially
@Bree and
@Wolfzz . Maybe one will help you..
TROUBLESHOOTING NETWORKING ISSUES
good reference-
Can't access shared folders from File Explorer - Windows Client
---------------------------------------
Open SERVICES. Make sure these services are set to automatic and running
DNS-Client – Server
Function Discovery Provider Host
Function Discovery Resource Publication
SSDP Discovery
UPNP Device Host and Windows Defender Firewall
------------------------------------------------------------------------
COMPUTERS NOT SEEN IN NETWORK MAP
Do this on all systems in network..
Add "LanmanWorkstation" as an additional startup dependency for the "Function Discovery Resource Publication" (FDResPub) service, which seems to do the trick. To do this, you simply open an elevated command prompt (i.e. use the "run as administrator" right-click context menu option to start cmd.exe), then execute the following command:
sc config fdrespub depend= RpcSs/http/fdphost/LanmanWorkstation
Reboot each device after executing this command, and the devices should see each other more reliably in Network and File Manager.

HOW TO CREATE A WINDOWS CREDENTIAL If you have password protected sharing turned on and it wants credentials.
Create a Windows credential for an account & password
on both client and server computers you are sharing files between.
Search for and open Credential Manager
To add a password to your Windows vault:
Click Start, type Credential Manager and select the name from the list.
Click Windows credential on the right.
Click Add a Windows credential.
In the Internet or network address box, type the name of the computer on the network that you want to access. (example: JoeBlowPC)
In the User name and Password boxes, type the user name and password that you use for that computer and then click OK.
