de/activate NIC by system interface/API calls?

Hi,

I'm not sure if I am in the right forum here .... so if I am wrong here, please point me to the right forum.

Now my question:
Is there a possibility to deactivate and activate a NIC with a (API) function or another Windows (XP) system interface/system call?

I would like to create a small programm which has the same effect as right-clicking on the network connection and selecting "Activate" or "Deactivate".

Thanks,
joft

Possibly also SetIfEntry() but may be unreliable.

Also, one can use SetupDi APIs (compilcated). Start with DICS_DISABLE, SP_PROPCHANGE_PARAMS, SetupDiSetClassInstallParams() and SetupDiChangeState().
