Dual Network Connections

NetSwitcher program will allow you to setup a laptop/computer for multiple domains and network configurations. You need to set it up then determine which network to logon to whenever you boot your computer.

Software costs $14 and is available for download at:

You could try different Hardware Profiles.

Right Click on "My Computer", select "Properties", then click the "Hardware" tab. Click the "Hardware Profiles" button. Copy and rename your current profile. Reboot, and select that profile. Make the necessary changes. This will, of course, require a reboot whenever you want to use a different domain controller/network, but it will save you from having to purchase third-party software.
