I have an application written in C# that needs to be able to configure the network adapters in Windows. I have this basically working through WMI, but there are a couple of

You could use Process to fire off netsh commands to set all the properties in the network dialogs.

eg: To set a static ipaddress on an adapter

netsh interface ip set address "Local Area Connection" static 192.168.0.10 255.255.255.0 192.168.0.1 1

To set it to dhcp you'd use

netsh interface ip set address "Local Area Connection" dhcp

To do it from C# would be

Process p = new Process();
ProcessStartInfo psi = new ProcessStartInfo("netsh", "interface ip set address \"Local Area Connection\" static 192.168.0.10 255.255.255.0 192.168.0.1 1");
p.StartInfo = psi;
p.Start();

Setting to static can take a good couple of seconds to complete so if you need to, make sure you wait for the process to exit.
