At recent newsletter from WindowsNetworking.com, author Robert J. Shimonski wrote about Netsh, a Windows based command line tool that if you master, can be very helpful in quickly getting your network setting changed from the command line without having to navigate the GUI for all your setting changes.
The Netsh tool once mastered can make life much easier for you and your administration of systems on your network or at home. In this article we will also look at how to create files to simplify changes further.
You will truly appreciate this tool. Changing network settings is just one of the functionality. You could also work with anything from IPSec to Windows Firewall (Win. Xp SP2)
