The Server Message Block 1.0 (SMBv1) network show is disabled normally in Windows Server 2016/2019 and Windows 10.

  1. Accepting there are no SMB 1. x clients left, we thoroughly cripple SMBv1 on all Windows devices.
  2. By impairing SMB 1.0, we safeguard Windows PCs from a wide extent of shortcomings in this legacy show.
  3. Likewise, the contraptions will use new, more useful, secure, and useful variations of the SMB show when getting to coordinate offers.

Of course, old client variations can get to organize shared envelopes exclusively by using SMB v1.0 show. “Disable SMBv1 Group Policy”, Expecting there are no such clients in the association, we can absolutely debilitate SMB 1.0 for record servers and client workspaces.

Looking at Shared Folder Access through SMB v1.0

“Disable SMBv1 Group Policy”, To do this, we engage the audit of record server access over SMB v1.0 using the going with PowerShell request:

  • Set-SmbServerConfiguration, AuditSmb1Access $true

Similarly, following a few days, we open the Event Viewer on the server and truly investigate the sign in Applications and Services – > Microsoft – > Windows – > SMBServer – > Audit. Check if any clients move toward the recording server over SMB1.

To show the summary of events from this event log we use the request:

  • Get-Win Event - Log Name Microsoft-Windows-SMBServer/Audit

Here, an event with Event ID 3000 from the SMBServer source is found in the log. “Disable SMBv1 Group Policy”, The event shows that the client 192.168.1.10 is trying to get to the server using the SMB1 show

  • SMB1 access
  • Client Address: (IP address)

It is possible either by using Server Manager or through PowerShell. Check to accept that SMBv1 is enabled using the PowerShell request:

  • Get-Windows Feature | Where-Object {$_.name - eq "FS-SMB1"} | ft. Name, Install state

To present the FS-SMB1 incorporate, run:

  • Present Windows Feature FS-SMB1

Likewise, to uninstall the SMBv1 client feature (requires a reboot), run:

  • Uninstall-Windows Feature – Name FS-SMB1 – Remove

Another PowerShell request that wipes out the SMB1Protocol incorporate is:

  • Weaken Windows Optional Feature - Online – Feature Name SMB1Protocol - Remove

For the server to manage SMBv1.0 client access, engage SMBv1 support at the SMB archive server-level regardless of the FS-SMB1 part.

Besides, to check, run:

  • Get-SmbServerConfiguration

“EnableSMB1Protocol: True” connotes we approach shared coordinators on this server using the SMBv1 show.

To weaken SMBv1 server support in Windows Server. We run the PowerShell request:

Since there is the same SMB arrangement technique in the standard Windows Group Policies, we want to impede it through the library practice.

  • Open the Group Policy Management console (GMC.MSc), make another GPO (disableSMBv1), and association it to the OU containing the PCs on which we really want to disable SMB1
  • Change to the game plan adjusting mode. Expand the GPO portion Computer Configuration – > Preferences – > Windows Settings – > Registry
  • Make one more Registry Item with the going with the setting:

Action: Update Hive: HKEY_LOCAL_MACHINE Key Path: SYSTEM\CurrentControlSet\Services\Lanman Server\Parameters Value name: SMB1 Value type: REG_DWORD Value data: 0

This course of action will incapacitate support for the SMBv1 server part through the vault on all PCs.

Similarly, to handicap the SMB client on region PCs through GPO, make an additional two library limits:

  • The Start limit (REG_DWORD type) with regard 4 in the vault key HKLM\SYSTEM\CurrentControlSet\services\mrxsmb10
  • The Depend On Service limit (REG_MULTI_SZ type) with the value Bowser, MRxSmb20, NSI (every value on a different line) in the reg key HKLM\SYSTEM\CurrentControlSet\Services\Lanmanworkstation.

It stays to invigorate the Group Policy settings on the clients (gpupdate/power). “Disable SMBv1 Group Policy” After the reboot guarantee that the SMBv1 parts are completely injured.

The Security Baseline GPOs from the Microsoft Security Compliance Toolkit have an alternate administrative design MS Security Guide (SecGuide.adml and SecGuide.all records) that have separate options for crippling the SMB server and client:
