win2k and standard protocol

i wonder how to tell win2k which network protocol to use first
(like the standard protocol selection in winX9)
e.g. if u have tcp/ip and netbeui installed and want to use netbeui to copy files and tcp only for internet sharing or something because its slower with files

i have 1 win2k and one ME computer and if I copy a file it takes me 2 times longer if a do it from an explorer in win2k sys than from the ME comp..because of the tranfairs using tcp/ip when launched from the 2k side (no matter which way i copy)

ill soon upgrade the ME comps hardware then it will also get win2k so the problem becomes bigger..
