DESCRIPTION

The Set-SmbServerConfiguration cmdlet sets the Server Message Block (SMB) Service configuration. For more information on SMB server and protocol specifications, see Overview of file sharing using the SMB 3 protocol in Windows Server and [MS-SMB2]:Server Message Block (SMB) Protocol Versions 2 and 3.

Note

The EncryptionCiphers parameter is available beginning with 2022-06 Cumulative Update for Microsoft server operating system version 21H2 for x64-based Systems (KB5014665), and Cumulative Update for Windows 11, version 22H2 (KB5014668).
The DisableCompression and RequestCompression parameters are available beginning with 2022-08 Cumulative Update for Microsoft server operating system version 21H2 for x64-based Systems (KB5016693), and Cumulative Update for Windows 11, version 22H2 (KB5016691).

EXAMPLES

Example 1: Set the SMB Service configuration

Set-SmbServerConfiguration -MaxChannelPerSession 16 -Confirm:$false

This command sets the SMB Service configuration without user confirmation.

Example 2: Turn on SMB signing and encryption

$Parameters = @{
    RequireSecuritySignature = $true
    EnableSecuritySignature = $true
    EncryptData = $true
    Confirm = $false
}
Set-SmbServerConfiguration @Parameters

This command turns on SMB signing and encryption without user confirmation. This example uses splatting to pass parameter values from the $Parameters variable to the command. Learn more about Splatting.

Example 3: Turn off the default server and workstations shares

Set-SmbServerConfiguration -AutoShareServer $false -AutoShareWorkstation $false -Confirm:$false

This command turns off the default server and workstations shares without user confirmation.

Example 4: Turn off server announcements

Set-SmbServerConfiguration -ServerHidden $false -AnnounceServer $false -Confirm:$false

This command turns off server announcements without user confirmation.

Example 5: Turn off SMB1

Set-SmbServerConfiguration -EnableSMB1Protocol $false -Confirm:$false

This command disables SMB1 on the SMB server without user confirmation.

Example 6: Specify encryption ciphers

Set-SmbServerConfiguration -EncryptionCiphers "AES_128_GCM, AES_256_GCM" -Confirm:$false

This command specifies the encryption ciphers used by the SMB client, and the preferred order without user confirmation.
