Switch network settings swiftly
In some circumstances it's useful to be able to switch network settings -- IP address, DNS settings, etc. -- for a Windows 2000 box "on the fly," without rebooting. The netsh command in Windows can be used to do this.
Open the command-line window and create a copy of your existing network settings by using the command:
netsh -c interface dump > networksetting.txt
This will write a copy of your existing network settings to a text file named networksetting.txt. The exact name of the file is arbitrary and can be placed anywhere you wish.
If you input the command
netsh -f networksetting.txt,
you can load the settings in the networksetting.txt file, which take effect immediately.
Though this system you can create text file dumps for as many network settings as you like, and then use Windows Scripting Host or simple command-line .BAT commands to switch between them as you need to.
