Please add the following to one of your source-file:

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

or you can add this lib (Ws2_32.lib) to the linker settings...

You also should change the subsystem in your linker settings from
"WINDOWS" to "CONSOLE" (I assume that you have a "_tmain" instead of a
"_tWinMain").

Hi Jochen,

Congrats on your MVP award.

I am indeed using _tmain and I set the linker settings to CONSOLE.
I also added lib (Ws2_32.lib) to the linker settings. But I still
getting the following error.

LIBCMTD.lib(wwincrt0.obj) : error LNK2019: unresolved external
symbol _wWinMain@16 referenced in function _wWinMainCRTStartup
Debug/TEST_SERVER.exe : fatal error LNK1120: 1 unresolved externals

Should I have the entry point set to wWinMainCRTStartup in the
linker settings? Your help would be greatly appreciated.

Thanks,
Paul.

Maybe you have defined "_WINDOWS" in your preprocessor-definitions?
Be sure that you have "CONSOLE" in your linker-sybsystem!
