    you can use several ways to find needed APIs:
    1-you can use monitoring such as APISpy,... to trace API running and find
    needed network access API.
    2-setting breakpoint on APIs such as gethostbyname(),... that usually use
    before connecting or other network APIs.

    And another suggestion:If you want to use this forum,You should use do
    what you promised in signature.Search before posting!

    sincerely yours

    You can also inspect the data being sent back to a server using some packet capturing software, such as Ethereal, which may or may not assist in reversing. Quite often some interesting info turns up in a packet capture, as people go to all the trouble of online registration checking but then forget (or cannot afford the server capacity) to protect the data being sent out.
    Still here...
