This error can occur if the Wsock32.dll or Winsock.dll file is missing, is damaged, or has been replaced by a sockets interface belonging to a third-party protocol stack.
Remove and reinstall the Transmission Control Protocol/Internet Protocol (TCP/IP). If you continue to receive this message, contact the vendor of the third-party protocol stack's interface and verify that the stack is compatible with Wsock32.dll or Winsock.dll.
