I am attempting to configure a Compaq laptop (running Windows XP with an on-board Ethernet interface) to physically connect to five separate sites that each have different network settings (IP address, subnet mask, and default gateway). The laptop should be able to connect to each site locally and access the network with minimal user intervention. (This almost reads like a Microsoft certification question, doesn't it?) I have not been able to effectively configure hardware profiles or user accounts to achieve this. Please help.
