unresolved external symbol error

I have tried following this tutorial to create an RPC server and client:
http://www.codeproject.com/Articles/...-to-RPC-Part-2

but i got this error:
error LNK2001: unresolved external symbol _Open

i'm not missing any files so i really don't know where the problem is


i attached the project so could someone please check them out and see why its causing this error?
