can't set up dial-up connecttion on laptop

i recently installed xp professional on my laptop that
was running w2000. after installation, my dialup
connection was gone. if i go to control panel, network
and internet connnections, setup or change internet
connections, internet properties, setup, new connection
wizard, connect to the internet, set up my connection
manually, ......... at this point, the next choice would
be "connect using a dial-up modem", however, that choice
in not activated and i can't click it.

my modem is shown on my harware profile.

any clues?????????
