Does anyone know how to check if the TCP/IP protocol is installed on a users
machine?

Also, is there a way to find out if the machine is running DHCP?

I have looked around in the registry and did find a key that had the IP address
for my machine:

MyComputer\HK_LOCAL_MACHINE\System\CurrentControlSet\Services\Class\NetTrans\0000

Thanks for any responses. Michael Bourns.
