Using PowerShell to disable network adapter bindings

You can enable and disable bindings on a network adapter using Windows PowerShell. For example, start by using the Get-NetAdapterBinding cmdlet to display the bindings for the specified interface:

PS C:\> Get-NetAdapterBinding -InterfaceAlias "Ethernet 2"

Name        DisplayName                                        ComponentID  Enabled
----        -----------                                        -----------  -------
Ethernet 2  Hyper-V Extensible Virtual Switch                  vms_pp       False
Ethernet 2  Link-Layer Topology Discovery Responder            ms_rspndr    True
Ethernet 2  Link-Layer Topology Discovery Mapper I/O Driver    ms_lltdio    True
Ethernet 2  Microsoft Network Adapter Multiplexor Protocol     ms_implat    False
Ethernet 2  Client for Microsoft Networks                      ms_msclient  True
Ethernet 2  Windows Network Virtualization Filter driver       ms_netwnv    False
Ethernet 2  QoS Packet Scheduler                               ms_pacer     True
Ethernet 2  File and Printer Sharing for Microsoft Networks    ms_server    True
Ethernet 2  Internet Protocol Version 6 (TCP/IPv6)             ms_tcpip6    True
Ethernet 2  Internet Protocol Version 4 (TCP/IPv4)             ms_tcpip     True

To disable a specific binding such as QoS Packet Scheduler, you can use the Disable-NetAdapterBinding cmdlet like this:

PS C:\> Disable-NetAdapterBinding -Name "Ethernet 2" -ComponentID ms_pacer

You can use the Enable-NetAdapterBinding cmdlet to re-enable the binding.
