Microsoft Multiplexor Protocol Windows 10

Active1 year, 11 months ago

After I upgraded my laptop from Windows 8.1 to Windows 10, my network connectivity was gone because all protocols were unchecked in the adapter settings. When I went to go turn them all back on, I got my network connection back, but I couldn't (and still can't) enable the Multiplexor protocol. When I select it and click 'Ok', a dialog informs me that my selections will cause it to be disabled:

Automated Restore. Select your Windows 10 edition and release, and then click on the Download button below. Save the RestoreMicrosoftNetworkAdapterMultiplexorProtocolWindows10.bat file to any folder on your hard drive. Right-click the downloaded batch file and select Run as administrator. Restart the computer to save changes. Microsoft Adapter Multiplexor Protocol is a special set of configurations that comes into play when a user combines two different connections. Actually, it is a kernel mode driver that is used for Network Interface Bonding. This means that two ethernet cards are combined to form one physical device in order to increase bandwidth.

Windows

If I click No, it returns me to the 'Ethernet Properties' sheet with the multiplexor protocol disabled. If I click Yes, it unchecks the multiplexor protocol and then closes the dialog and property sheet.

The googler wasn't very helpful, here. There are a few threads out there in which users express the same issue, but the support they received was quite useless.

Microsoft Network Adapter Multiplexor Protocol drivers were collected from official websites of manufacturers and other trusted sources. Official driver packages will help you to restore your Microsoft Network Adapter Multiplexor Protocol (network). Download latest drivers for Microsoft Network Adapter Multiplexor Protocol on Windows. What is the Microsoft network adapter multiplexor protocol It is basically a kernel mode driver used for Network Interface Card (NIC) bonding. By default, the protocol is installed as part of the physical network adapter initialization.

Microsoft Network Adapter Multiplexor Driver now has a special edition for these Windows versions: Windows 7, Windows 7 64 bit, Windows 7 32 bit, Windows 10, Windows 10 64 bit, Windows 10 32 bit, Windows 8, Windows Vista Home Basic 64bit, Windows 8 32bit, Windows 8 Enterprise 64bit, Windows Vista Ultimate 32bit, Windows 7 Professional 64bit, Windows 10 Mobile 64bit, Windows 7 Ultimate 64bit, Windows XP Home Edition, for home desktops and laptops 32bit, Windows Vista Enterprise (Microsoft.

I also tried to do this in PowerShell to see if it would either a) just work, or if it would b) give me a more useful error message.

Turns out that was really too much to hope for.

While reading it did occur to me to make sure the NdisImPlatform service was running, and I made sure using sc.exe:

After this, I tried the things I described above again, but to no avail.

Also, ultimately this is yak-shaving in order to get bridged networking to work in VirtualBox, and so I thought I might try to repair the VirtualBox installation (by running the installer again), but that didn't help either.

Anybody know why this is happening in Windows 10 and how I can fix it?

Microsoft Network Adapter Multiplexor Protocol should be left unticked. It is only used with NIC Teaming - i.e. where you have two physical network interfaces that are being used in a load balancing or redundant configuration. In that case the two physical NICs have only this binding ticked (all others cleared), and the team adapter has the normal bindings ticked - but not this one.

What version of Virtual Box are you running - I had the same problems, but decided to upgrade to the newly released version 5 of VirtualBox - which fixed the network adapters not displaying in Bridged mode, but I still have problems getting into the VM - Port 22 & 80 just won't connect inbound.

I can go out of the VM to the internet and can start (and connect to) the machine etc with the VirtualBox program, but I like to run things headless with VirtualBox manager on the command-line. :(

Ultimately I never found a way to fix this directly; I installed Virtual Box 5 - which I didn't realize had released until I was looking for a solution to this - and things went back to working.
