Share Files and Folders Over a Network in Windows 10  

If your NIC (Network Interface Controller) doesn't support "SMD Direct", it won't be available.

You might see if "SMB Direct" (RDMA) may get added after updating to the latest version 1903 build 18362.239.

My PC is reporting that Windows is up to date, and when I try to install the update using the msu file, I get the error message "The update is not applicable to your computer". I've tried a number of troubleshooting steps (including running DISM and SFC), but with no luck. I guess I should wait until the update comes through as an automatic update.

If you like, you could use the Windows 10 Update Assistant from Microsoft below to update to the latest version of Windows 10.

It looks like the NIC doesn't support SMB Direct (RDMA).

You would need to keep SMB 1.0 enabled on this PC.

You could try to only have SMB Direct enabled on the others to see how it works. If you have issues, then you could try SMB 1.0 enabled on them as well.

You're most welcome. Please let us know how it went.
