Mobile users often carry a laptop between work and home offices. Vista’s Alternate Configuration makes it easier for mobile users to switch between IP configurations.
For example, if IP addresses at your office are supplied through a Dynamic Host Configuration Protocol (DHCP) server, your primary IP configuration can be set to obtain an IP address automatically. At home you may require a static IP address. Instead of having to reconfigure IP settings each time, the Alternate Configuration is used in the event that a DHCP server is not available. So when you do plug into your home network with no DHCP server, the static IP settings specific by the Alternate Configuration are used instead.
You can enable the Alternate Configuration feature in Vista using the following steps:
- Click Start, right click Network and click Properties.
- Select Manage network connections.
- Right click your network connection and click Properties
- From the list of network components, select Internet Protocol (TCP/IP) and click the Properties button.
- From the Internet Protocol (TCP/IP) Properties window select the Alternate Configuration tab.
Specify the IP parameters that should be used should the primary IP configuration fail.
