Windows 10: Enabling network sharing with smbv1 disabled and smbv2 enabled

We all know about how people at microsoft make smbv1 mandatory to share folder across a local network, which exposes us to ransomwares. people at Microsoft have no concerns for security, despite being in IT business for the last 30 years....
in windows 10 , like 1809, the trick is to enable smbv2 and disable smbv1, but like they say here it prevents some background process to start SMB1 disabled, SMB2 enabled; Can no longer access network shares

Fortunately i found a blog on how to get file sharing securely

first put back the windows firewall to default settings, to be sure

just to be sure, get those two new services enabled

get-Service fdPHost,FDResPub|Set-Service -startuptype automatic -passthru|Start-Service

then follow all those lines Mapped network printers unavailable due to SMB1 being obsolete – Xenit Technical

Enable SMB v2 Client
sc.exe config lanmanworkstation depend= bowser/mrxsmb10/mrxsmb20/nsi
sc.exe config mrxsmb20 start= auto

Enable SMB v2 Server
Set-ItemProperty -Path "HKLM:\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters" SMB2 -Type DWORD -Value 1 Force
Restart
Disable SMB v1 Client
sc.exe config lanmanworkstation depend= bowser/mrxsmb20/nsi
sc.exe config mrxsmb10 start= disabled

Disable SMB v1 Server
Set-ItemProperty -Path "HKLM:\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters" SMB1 -Type DWORD -Value 0 Force
Restart

Detect SMB v2 Client status
sc.exe qc lanmanworkstation

Detect SMB v2 Server status
Get-ItemProperty HKLM:\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters | ForEach-Object {Get-ItemProperty $_.pspath}




You can also check you have smbv1 disabled with

Get-SmbServerConfiguration | Select EnableSMB1Protocol, EnableSMB2Protocol

THe official command lines by microsoft are those

Get-SmbServerConfiguration | Select EnableSMB1Protocol, EnableSMB2Protocol
Get-WindowsOptionalFeature Online FeatureName SMB1Protocol
Disable-WindowsOptionalFeature -Online -FeatureName SMB1Protocol
Enable-WindowsOptionalFeature -Online -FeatureName SMB1Protocol
Get-SmbServerConfiguration | Select EnableSMB2Protocol
Set-SmbServerConfiguration EnableSMB2Protocol $false
Set-SmbServerConfiguration EnableSMB2Protocol $true

Is there an easy way to activate SMBv2 or v3 on windows 10?

Hi Bill,

By default, the Server Message Block is enabled in Windows 10 devices. However, if SMB is disabled, running commands in PowerShell can enable it. For us to provide an effective solution, we would need you to answer the following questions:

• Which build and edition of Windows 10 is installed on your device?
• Are you using a Windows Server?
• Is the device connected to a domain network?

In the meantime, you can check this link. It serves as a guide on how to
detect, enable and disable SMBv1, SMBv2, and SMBv3 in Windows and Windows Server.

We'll be waiting for your reply.

Network sharing not working after installing Cumulative updates on Windows 10 1809

Hi,



Thank you for writing to Microsoft Community Forums.



I understand that you are facing issues while using the network-sharing feature after installing cumulative updates.



Thank you for bringing this to our notice. I also appreciate your efforts in trying to resolve the issue by performing the troubleshooting steps.



As you have mentioned that certain cumulative updates are causing the network-sharing feature to fail, it would be great if you can provide the KB number of the cumulative updates, which are causing the issue. So, we can look into
this for you.



Also, for more clarity on the issue, please respond to the questions below.

1. Which build version of Windows 10 is installed on the PC’s?
   
2. What is the make and model of the PC’s?
   

Meanwhile, I would suggest you to enable SMBv1.0 on all the systems and check if that helps. Refer the section
How to gracefully remove SMB v1 in Windows 8.1, Windows 10, Windows 2012 R2, and Windows Server 2016, and the sub-section
Windows 8.1 and Windows 10: Add or Remove Programs method in the article

How to detect, enable and disable SMBv1, SMBv2, and SMBv3 in Windows and Windows Server.



If the issue persists, please get back to us with the details and the results of the troubleshooting steps to assist you further.
