Win2k Pro in multiple domains

I am the Systems Manager for a consulting firm that places project managers within other organizations. We run Win2k Pro, or server, on our laptops and want to set up to use our internal domain when in the office, and set up to log into other domains when on the road. We tried setting up hardware profiles, but that didn't work. Is there any way to set up Win2k to hold multiple network profiles?

Thanks,
