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.
