Disable Network Adapter

[rayramsey2000]

I'm writing an application which needs to control one of the network adapters (disable then later re-enable it). I've found an MSDN tool called DEVCON which does a wonderful job at doing this, but it uses classes of hardware and vendors as the filter for what to take actions, so if I use this then it dissables all 3 network cards on the PC. I have looked for days on the net and in reference books and can't find anything to do this.

Thanks in advance for any help in the right direction

Also sorry for placing in this group, but I couldn't find one for this type discussion
