I don't have a Win98 PC to see if this would work on 98.
Q. How can I easily configure my Windows 2000 notebook for different
networks?
A. If you use your Win2K notebook in a variety of networks (e.g., at
different customer sites), you probably always have to change the
network settings. The Netsh utility lets you save your settings in a
file that you can later use to restore your complete network settings.
To Save the current Settings, type the following command:
netsh -c interface dump >networksetting.txt
You can then create a dump file for every network that you use.
To load a set of settings again, type the following command:
netsh -f networksetting.txt
Using the Netsh utility, you can also easily switch between different
configuration settings.
