If your ethernet adapter is set for DHCP you can just use ipconfig /release and it wont have an IP or the ability to route. There is a nifty command in 2k3 server but it doesnt work the same in XP appearantly. Alternatively you can use this

http://download.microsoft.com/download/1/1/f/11f7dd10-272d-4cd2-896f-9ce67f3e0240/devcon.exe

Use the command:
devcon disable "devicename"

Make sure you save devcon inside system32.

Can you do anything with the Netsh command?

That's what I was thinking - use netsh to assign a bogus gateway (127.0.0.1). This does not really 'disable' the adapter however, if that's what you're really after for some reason.

If the computer is set to dynamic ip addressing run from command prompt
ipconfig /release

followed by
net stop dhcp

This would release the IP address and then stopping dhcp would or should stop the renewal of the IP address and the pc would not get an IP address

to start it again run
net start dhcp
followed by
ipconfig /renew
