Hello,

I've been trying to disable the network interface card from within the code in C using Windows. Something like: ifconfig eth0 down, in linux. Is there a way to do this from code in Windows?

Thanks a lot.

Seems nobody here's picking this one up, so although I don't have much to contribute (since I'm an ardent Unix man), I'll say the most helpful thing I know: if there's a way to do this conveniently from code (and I wouldn't be surprised if there wasn't; I fear programming for Windows, I truly do), I suspect it's a Win32 API thing. If not, I'm not sure, and this might be a wrong turn, but maybe doing something with rundll (calling it with system()) is the answer; I don't really know, but I remember this does allow you to shut down Windows machines with:


or something similar.

I hope this has been at least a little helpful, but like I say, I'm really not a Windows man so I'm not sure and I apologise if I've sent you down any blind alleys.

not sure about C++ (may want to Google for it)...

Although in WMI ...
You cannot enable/disable the NIC, but you can disable the network connection.

(haven't tested)

strComputer = "."
Set objWMIService = GetObject( _
"winmgmts:\\" & strComputer & "\root\cimv2")
Set colNetCards = objWMIService.ExecQuery _
("Select * From Win32_NetworkAdapterConfiguration " _
& "Where IPEnabled = True")
For Each objNetCard in colNetCards
objNetCard.ReleaseDHCPLease()
Next

An extensive list of WMI scripts are available here:

tempest

system("ipconfig /release");

Does the same thing as IR's code but a little simpler.

Now where is the fun in simplicity? j/k
