Enable or Disable SMB1 File Sharing Protocol in Windows

Badabing · 12 Feb 2020

....not just enable/disable SMBv1.

If it isn't installed, it doesn't show up. At all! THAT's the problem.

I probably don't completely understand your particular problem. Are you saying it does not even show up in Windows Features? If not, I see your issue. If that's it, look here and see if you have it in the Settings>Apps>Apps and Features>Optional Features, and install it.

But... how?

I googled for days (!) how to do that, not just enable/disable SMBv1.

Hello Badabing,

Please post a screenshot showing what you see instead to see if anything may standout.

SMB1 is a part of the OS, so it usually only needs to be enabled or disabled.

CVE-2020-1301 | Windows SMB Authenticated Remote Code Execution Vulnerability

Hi folks
If you have Linux NAS's or other hardware that requires SMB1 then it's quite safe in the LINUX SAMBA config (/etc/samba/smb.conf) file to put in the global setction the following line : min protocol = NT1. This will allow connectivity even though the SMBV1 protocol on Linux will be disabled. (Some people used to have max protocol = NT1 -- change it to MIN protocol if using releases of samba > 4.10.X).

I don't think on Home computers (typical Mom and Pop type of machines) that one should be overtly worried about the security with SMB1 -- IMO at least -- we aren't running at home enterprise levels of networks or need to be protected from N.Korea, China or other "rogue state" elements from hacking a nations infrastructure etc etc.

Corporate / enterprise / commercial servers probably yes - but home networks !!!!!

Cheers
jimbo

After a couple of hours I finally managed to get all the different updates in to Win 7 and then install Powershell..

I used the instruction to get SMB in that PC and presumably it works. Is there any way of confirming that SMB is now active in that OS?

Great news so far Tony.

You could check the registry key and value to see what's it currently set to confirm.

Of course, the real test is if the computers are able to see each other or not.

I'm running windows 10 home 20H2. I noticed under my windows turn features on or off SMB 1.0/CIFS File sharing support does not have any check marks there. I did not touched anything so should this be turned on?

Hello Purpleroses,

SMB 1.0 is turned off by default for security reasons.

You would only want to turn on SMB 1.0 if you are sharing files with a computer on your private network that is using a previous version of Windows (ex: Windows 7).
