A new Windows 10 Pro laptop did connect to the Windows Server 2016, but then stopped.working. In fact, I had created Desktop links to the server, which would not have been possible if the connections did not work. Now it just does this.

1) I have seen strange errors like this when Offline File were on, but they were Off. I tried turning them on, and then back off. No change.

2) I tried installing all current Windows updates. No change.

3) I tried connecting to the server with both the user and Administrator accounts, and got the same issue.

4) I tried connecting to a Windows 10 Pro workstation with two folder shares, and that worked fine.

5) I tried adding the server as a Trusted site. No change.

6) I can ping the server from the laptop.

7) Another Windows 10 Pro laptop with the same username can connect to the server fine.

I am out of ideas. Any help would be appreciated.

    For the newer OS's enabling File and Printer Sharing plus network discovery may help.

    Check these services are started on all members DNS Client, Function Discovery Resource Publication, SSDP Discovery UPnP Device Host and also check the firewalls allow Network Discovery for the network profile you're using (in my example below using domain).

    @Michael Adams Hi,

    Thank you for posting in Q&A!

    After my research, I would suggest you:
    1.First check if win10pro do have permission in both Share and Security tab (share and NTFS permission).

    2.According to some similar case, please try to delete this shared folder and recreate.(Remember to backup)
    The following two case was solved by this method.

    I appreciate everyone's help. So after running the tests you suggested, I determined that while this laptop was being used at an employee's house and connecting to the server with a VPN, the employee had a device at their house on exactly the same IP address as the server! Why another laptop also at the employee's house using the same VPN did not have a problem connecting to the server is a mystery.

    Thank you both for your suggestions and help. I am going to keep your debugging techniques in mind for the future.
