Unable to assign static IP address on laptop

I have Win2000 Server on a laptop, a Dell Inspirion 2650 with a 3Com
3C920 Integrated Fast Ethernet NIC. It needs to be useful in the
field where it will be used to show sample web sites, each of which
will have its own IP address, although they could share an address and
simply use different ports. The problem is that since the laptop is
not actually connected to a network, the only address available for
use is 127.0.0.1:80, no matter how many addresses I've assigned the
machine.

I can duplicate this problem on a desktop computer simply by
disconnecting it from the network, at which time only 127.0.0.1 is
available for use. I plugged the laptop into the network without
moving it from its unique workgroup and it functioned perfectly; it
just seems to require being connected to a live NIC in order to
utilize more than one address.

I've installed Win2000 Professional & Server on scores of machines,
and this installation was no different from any of them; there were no
errors at all. Does anyone know of a work around for this, something
that will allow me to make use of several different IP addresses on a
machine that's not connected to any network?
 
Tci/ip protocol of win2k will not see a netcard when it's cable is disconnected from network.
This is by design.
1. Connect netcard of your laptop to a hub so it will look as connected to the machine.
2. Assign to this netcard as many static IP addresses as you want.

Edit the registry:
HKLM\SYSTEM\CCS\Services\Tcpip\Parameters, value DisableDHCPMediaSense,
value type: REG_DWORD, data 1. Reboot.

Thanks for the suggestion, but this idea was already discarded since
it would require a hub to be plugged in somewhere, and when I said
this laptop would be in the field, I was being quite literal. There's
no guarantee it'll be near any external power source, not even a car
battery, and the only hubs I know of which run off the computer's own
power are USB, which the computer cannot use.

This worked flawlessly. Many thanks.
