PowerShell Set-NetAdapterBinding

last modified February 15, 2025

This tutorial covers the Set-NetAdapterBinding cmdlet in PowerShell. It is used to enable or disable network adapter protocol bindings. This helps manage network connectivity and optimize performance.

Network adapter binding basics

Network adapter bindings determine which protocols and services can use a network adapter. Each adapter can have multiple bindings for different protocols. The Set-NetAdapterBinding cmdlet modifies these bindings. This is useful for security and performance tuning.

Basic Set-NetAdapterBinding usage

The simplest usage enables or disables a binding on a specific adapter. You need the adapter name and component ID. The -Enabled parameter accepts $true or $false values. This example disables IPv6 on an adapter.

binding1.ps1

Set-NetAdapterBinding -Name "Ethernet" -ComponentID "ms_tcpip6" -Enabled $false

This command disables IPv6 binding on the Ethernet adapter. The component ID "ms_tcpip6" identifies the IPv6 protocol. No output is returned by default.

Enable a binding on all adapters

You can modify bindings across all network adapters. Use the wildcard character (*) for the -Name parameter. This example enables Link-Layer Topology Discovery on all adapters. Be cautious with global changes.

binding2.ps1

Set-NetAdapterBinding -Name "*" -ComponentID "ms_lltdio" -Enabled $true

This enables the LLTD protocol on every network adapter. The component ID "ms_lltdio" refers to Link-Layer Topology Discovery. Verify changes with Get-NetAdapterBinding.

PS C:\> Get-NetAdapterBinding -Name "Ethernet" -ComponentID "ms_lltdio"

Name                      DisplayName                                        ComponentID          Enabled
----                      -----------                                        -----------          -------
Ethernet                  Link-Layer Topology Discovery Responder           ms_lltdio            True

Disable bindings using pipeline

PowerShell's pipeline can simplify binding management. First get adapters with Get-NetAdapter, then pipe to Set-NetAdapterBinding. This example disables NetBIOS over TCP/IP on wireless adapters.

binding3.ps1

Get-NetAdapter -Name "Wi-Fi*" | Set-NetAdapterBinding -ComponentID "ms_netbios" -Enabled $false

This disables NetBIOS on all adapters with names starting with "Wi-Fi". The pipeline passes adapter objects directly to the binding cmdlet. This approach is efficient for bulk operations.

Check current bindings before changes

It's good practice to verify current settings before making changes. Combine Get-NetAdapterBinding with Set-NetAdapterBinding. This example shows checking then disabling a binding.

binding4.ps1

$bindings = Get-NetAdapterBinding -Name "Ethernet" -ComponentID "ms_server"
if ($bindings.Enabled) {
    Set-NetAdapterBinding -Name "Ethernet" -ComponentID "ms_server" -Enabled $false
}

This script first checks if the File and Printer Sharing binding is enabled. Only if enabled, it disables the binding. The ms_server component ID represents this service.

Enable multiple bindings with a script

You can manage multiple bindings in a single script. Create an array of component IDs and loop through them. This example enables several protocols on a specific adapter.

binding5.ps1

$components = @("ms_tcpip6", "ms_lltdio", "ms_rspndr")
foreach ($comp in $components) {
    Set-NetAdapterBinding -Name "Ethernet" -ComponentID $comp -Enabled $true
}

This script enables IPv6, LLTD, and Link-Layer Topology Discovery Responder on the Ethernet adapter. The array contains component IDs for each protocol. The foreach loop processes each binding sequentially.
