Windows 7: Restrict ACtive NICs

Restrict ACtive NICs

Hey there

I would like to know if there is a way to restrict the total number of NICs to one.
I would like to make sure no machines are multi-homed (connected to an internet only wireless connection, whilst connected to a corporate LAN, for instance).

Is there a way to do this?

Thanks

Hi Moo,

Yes but you would need to create your own application or script that monitors each adapter that you can keep connected while disabling the others, it would require a fair amount of work however.

Or you could just disable the un-used NICs in device manager.

Actually, I can't disable the NICs. For instance, if a laptop user has wireless, they will need to connect to wireless networks, but they will also be able to connect to the wired network.

So, although I need all NICs active, I just want to make sure that no one can connect to more than one network at any one time.

Windows will not use both adapters at the same time and what I mean by that is if a machine is connected via Wireless for Internet and connected via Ethernet for domain access then Windows will not try accessing the Wireless internet for domain machines and vice versa for Internet access it will not try accessing the domain network

What your asking is impossible though unless you create an application to monitor the NICs and disable the other one when another become active
