The wonders of NetSH!
NetSH is one of the most powerful command line tools available to Windows XP
and Windows Server 2003.
I thought I would give you two examples of it's power and then an outline of
some of the other commands followed by some links to the Microsoft Web Site.
One of my students Peter also sent me an email which spurred my on to finally put something up here about netsh. I have placed his tip at the bottom, thanks Peter.
Netsh interface ip set
I use this command to change the ip addressing details on my network cards when I move my laptop between home and work. For example...
netsh interface ip set address name="Xircom" source=static 192.168.22.200
255.255.255.0 192.168.22.1 10
netsh interface ip set dns name="Xircom" static 192.168.22.201 primary
netsh interface ip set address name="3Com" source=dhcp
Netsh diag ping gateway
this command will automatically ping all of the computers default gateways
without needing to know what they are. See the example output below...
