In Windows, running a command to disable SMBv1 and then a command to enable SMBv2 and SMBv3 stops the SMB service. To force Windows to use SMBv2 and SMBv3, you only need to disable SMBv1.
If you tried to disable SMBv1 and are now unable to connect to the NAS via SMB, run the following two commands in an elevated command prompt and then restart Windows:
sc.exe config lanmanworkstation depend=bowser/mrxsmb20/nsi
sc.exe config mrxsmb10 start=disabled
