The following errors are from a file with just windows and winsock2 included.

What's already been tried : placing the winsock.dll file in the same directory as the compiler and program to be compiled, placing it in the system32 directory, and entering it in the registry with the regsrv32 command. Don't really know where to go from here, appreciate any advice . . .
