Link against this.
for future reference, MSDN will tell you exactly what you need, so be sure to use it when in doubt.

Also make sure you read up about Winsock includes and libs, they must be included before you include windows.h
Some more info on the headers:

Lol that pissed me off when I was first writing detours for winsock, I was declaring includes for the libraries and headers after windows.h =\ hundreds of errors  Figured it out after a short while though.
Come to think of it, I never finished the project.. I think it was crashing every time I injected, ended up making a proxy instead. Will have to revive that project and get it working.

Yea when I was doing some random projects with it I ran into the issue too, looked up the funcs and found that article and was like "wow... so many errors for such a stupid reason.." Figured they would add a #ifdef block at the top of the winsock file to determine if windows.h was included already and just die on that. But no...
