C++ WinSock2 Errors - c++

Question

Yesterday I've tried to make a socket server in C++, but I get errors upon compiling.
The errors:
Error 6 error LNK2019: unresolved external symbol _imp_socket#12 referenced in function "public: static unsigned long __cdecl Env::GetSocket(void)" (?GetSocket#Env##SAKXZ) C:\Users\JoshuaTha\Documents\Visual Studio 2010\Projects\HabboV5\HabboV5\Network.obj HabboV5

#include "stdafx.h"

using namespace std;
int _tmain(int argc, _TCHAR* argv[])
{
cout.write("hi", 2);
cout << "Hello World!" << endl;
Env::Network = new Network();
Env::Network->Start();
while (1)
{
char input[256];
cin.getline(input, 256);
}
}
Network.h:
#pragma once
#include <WinSock2.h>
class Network
{
private:
SOCKET socket;
public:
Network(void);
void Start();
};
Network.cpp:
#include "StdAfx.h"

}
void Network::Start()
{
this->socket = Env::GetSocket();
SOCKADDR_IN sInformation;
sInformation.sin_family = AF_INET;
sInformation.sin_addr.s_addr = INADDR_ANY;
sInformation.sin_port = htons(30000);
bind(this->socket, (SOCKADDR*) (&sInformation), sizeof(sInformation));
listen(this->socket, 10);
}
Env.h:
#include "stdafx.h"
#include "Network.h"
#include <WinSock2.h>
class Env
{
public:
static Network* Network;
static DWORD GetSocket()
{
return socket(AF_INET, SOCK_STREAM, IPPROTO_TCP);
}
};

In the linker options (on the project right-click, linker, input) you need add wsock32.lib or ws2_32.lib to the list of input files.
