Hello jimspy, welcome to the Microsoft community my name is Luiz Cruz, I am a Windows 10 expert user and would be happy to help you;
I understand that you are having difficulties accessing the server's network;
Initially I recommend that you try the following:
Press Windows key + I and access settings;
Click on Network and Internet;
Scroll down and click Network and Sharing Center;
On the left of the screen, click on Advanced Sharing Settings;
Click the down arrow next to Private and enable the options: Enable network discovery, Enable automatic configuration of network connected devices, and Enable file and printer sharing;
Click the down arrow next to Guest or Public and check the options: Enable network discovery and Enable file and printer sharing;
Click the down arrow next to All networks and check the options: Enable sharing so anyone with network access can read and write files in public folders and Disable password-protected sharing;
Click Save Changes;
Note: Do this on all computers you want to access the network;
I hope I helped, see you soon!
