Why can't I connect to my NAS via SMB after disabling SMB1 from the command line?

Scenario

After disabling SMB v1 and enabling SMB v2/3 via the command line on Windows Server 2012, users can no longer connect to the NAS via SMB.

Solution

In Windows Server 0212, running a command to disable SMBv1 and then running a command to enable SMBv2 and SMBv3 stops the SMB service completely. To force Windows to use SMBv2 and SMBv3, you only need to disable SMBv1.

You can fix the issue with the following process.

On the Windows device, open an elevated command prompt.

Run the following commands:

sc.exe config lanmanworkstation depend= bowser/mrxsmb20/nsi
sc.exe config mrxsmb10 start= disabled

Restart the device.
