Windows 10: SMB Direct refusing to enable - W11

SMB Direct is refusing to enable, clicking the check button within "turn windows features on and off" unticks itself after saving. This is required for scan to folder.

Cannot enable SMB

I have the exact same problem as described in this post from 2018:

Redirecting

I am not able to enable SMB /CIFS from the "Turn Windows features on or off" : I am allowed to click on the checkbox (upper level), but then get the error message 0x80073701.

I did try the suggestion as described in the link above (disabling SMB1 and SMB2 in the registry, restart, re-enabling), but this does not work for me.

I am aware of the danger of SMB 1; in this case, the computer is not directly connected to the internet, and the reason I need SMB/CIFS activated is so that our synology can mount cifs share within the internal network.

Our version of windows is Microsoft Windows 10 Enterprise LTSC, 10.0.17763.

Thanks for your help!

Windows 11 SMB Direct feature has stopped working

My Windows 11 23H2 machine is behind a NAT router in a WORKGROUP type network. Previously, I could browse shared folders on it from other machines on my network using UNCs like "\\dev9\Downloads".

Recently, this feature has stopped working. In Windows File Explorer on the other machine I can actually see my Windows 11 machine (DEV9) but when I double-click to drill to the shared folders from another machine on the network I see the following error message:





Both machines have 'SMB Direct' enabled and 'SMB 1.0/CIFS File Sharing Support' disabled. The 'Diagnose' button concludes there is no problem.

If I enable 'SMB 1.0/CIFS File Sharing Support' on both machines then accessing shared folders on DEV9 works, but my understanding is that this option is insecure and that 'SMB Direct' should be used (and previously was successfully working).

If I set up a shared folder on another networked Windows machine that only has 'SMB Direct' enabled (not 'SMB 1.0/CIFS File Sharing Support') then that works - i.e. I can access it from DEV9.

Both machines are always logged in with the same user name and password (and no authentication UI is presented).

I have tried unchecking, rebooting and rechecking the 'SMB Direct' option on DEV9 but to no success and have run out of ideas. I cannot pinpoint the exact time at which the functionality stopped working, but definitely in the last few weeks. So possibly a Windows Update issue, though Googling has not been helpful in this case.

So, if anyone has a solution or some suggestions I'd be very grateful indeed. Thanks!

How to solve problems with accessing, discovering and connecting to NAS with SMB connection from Windows 10

I am experiencing difficulties with accessing, discovering and connecting to my NAS with SMB connection from Windows 10.

I have tried most of the solutions suggest on the Web, but avail, none of them worked.

• Enabling SMB v2 and restarting
• Checking SMB v1 in Windows components is ticked on
• Etc.

It seems that Microsoft has broken something though their patches

If anyone can supply me with a permanent/ final fix,
not workaround, please post it here.
