Windows ifconfig

• like http://www.leastprivilege.com/UPDATEDIfconfigForWindows21.aspx but more UNIXish
• unix syntax
• take interface up/down
• view/set ip address, subnet mask, broadcast address
• view/set mac address
• Interface Aliasing: {…} becomes ndisN
  • Mapping at generic location in Registry
  • Mapping used by ifconfig and pfctl
• tcpip.sys Registry Settings KB314053
  • How to make changes effective with minimal system interruption?
• WMI (see Platform SDK):
  • NetworkAdapter, NetworkAdapterConfiguration WMI classes (vbscript)
  • Automatisieren von TCP/IP-Netzwerken auf Clients
  • Win32_NetworkAdapterSetting WMI class
  • Win32_NetworkAdapter WMI class
  • Win32_NetworkAdapterConfiguration WMI class
  • WMI sucks big time on anything non-Vista! Need COM to do anything useful like enabling/diabling an interface.
• COM
  • INetConnection COM Interface
• MAC Address Changer
