Is there a way to change my TCP/IP settings using Ruby scripts. For  
example I want a quick way to setup from DHCP to fixed IPs. My Windows  
is 2000.  
Kind Regards

Windows 2000 comes with the netsh command line tool, which will allow  
you to  
do this easily:

Set a static IP:  
netsh interface ip set address name=“Local Area Connection”  
source=static  
addr=192.168.0.10 mask=255.255.255.0 gateway=192.168.0.1 gwmetric=1

Set an interface for DHCP:  
netsh interface ip set address name=“Local Area Connection” source=dhcp

While this link is for XP, the syntax for 2000 should be the same:

us/netsh.mspx?mfr=true

If you need to do this from a Ruby script, you can shell out for the  
above.  
I’m not aware of any libraries for this.
