Unresolved external symbol LNK2019

by

The problem is you are not linking against the Ws2_32.lib library. To fix this you can add that to your additional dependencies tab of linker/Input settings for your project. Alternatively (as pointed out by SChepurin in the comments) you can add 

#pragma comment(lib, "Ws2_32.lib")

to a source file of your project.
