Windows Server 2019 cannot see devices on the LAN

0

I just installed (and activated) Windows Server 2019 Standard. It is set up in a workgroup and has the same workgroup name as all other PC's. All other PCs can access each other's shares (even the servers shares) but the server cannot see any shares. Given the server's IP address of 192.168.0.3, whenever I try to access another PC's share from the server using

\\192.168.0.4\Share1

After a few seconds, I get the following message

Windows cannot access \\192.168.0.4\Share1. Check the spelling of the name. Otherwise, there might be a problem with your network. To try to identify and resolve network problems, click Diagnose.

Clicking Diagnose just tells me no issues were found.

The only things I can find when searching this issue are questions about not being able to access the server's shares. That's not my issue. The issue is that the server can't access the other shares on the network.

Any suggestions?

Does \\192.168.0.4 work (without the share name)? Can you ping 192.168.0.4 from the server? – Sam Forbis – 2020-02-21T20:35:18.803

No, it does not work with or without a share name. And yes, it does ping from the server. – tolsen64 – 2020-02-21T20:53:54.917

I should also say that in file explorer when you look at "Network", it finds all the other computers on the LAN. Double-clicking on any of them returns a similar message as described in the question. – tolsen64 – 2020-02-21T20:56:30.780

Figured it out and fixed it. The answer was found here and here. Basically, Windows Server 2019 disables guest access in SMB2 by default. Had to enable insecure guest logons in the group policy editor.

Computerconfiguration\administrative templates\network\Lanman Workstation "Enable insecure guest logons"
