Reduce hassle by using one network interface card for two networks in Windows 2000 Professional

Do you ever find yourself reconfiguring your Windows 2000 Professional network settings wherever you take your laptop? Here's how to configure one network interface card for two different environments.

If you use a laptop and switch between different networks, you might find yourself having to reconfigure your Windows 2000 Pro network adapter settings each time you switch.

For example, perhaps you have one set of settings at the office and a different set of settings at your home office. When you take the laptop home, you have to reconfigure it for your local network settings (e.g., switching from a public IP address at the office to a private IP address at home).

To reduce the hassle, you can take advantage of a little-known behavior in Windows 2000 that will help you circumvent the trouble. Windows 2000 maintains network configuration settings for network adapters on a laptop based on the adapter's slot. This also means that you can maintain two different sets of network configuration settings by moving a single adapter between the slots.

So, you might assign one IP address to the adapter when it's in slot 0 and a different IP address when it's in slot 1. Then, when you need a particular configuration, simply reboot the computer with the adapter in the appropriate slot.

To set up your computer in this way, boot the system with the card in slot 0 and configure the network settings as needed for the first network. Verify that the network is working, then shut down the computer. Move the adapter to slot 1 and boot the computer. Configure the new settings and test on the second network.
