Can't port Linux TCP socket program in C to Windows - c

Question

I'm trying to import C programs, which demonstrate TCP socket programming in the Linux environment, into Windows. In the following two programs, the commented out include statements work in Linux and the includes below them are the Windows equivalent that I put. However, when I'm running these two programs, the server and the client produce the following errors respectively.
Error from simple_server
Socket received successfully...Failed to listen...
Error from simple_client
Read Error
All the equivalent Windows includes were taken from a long Stackoverflow searching session itself..:D. However, I'm stuck here not understanding why my server is not running. Any helpful advice and suggestions are highly appreciated.
My code
simple_server.c

// Windows equivalent to sleep() in unistd.h

int main (void){
int listenfd, connfd = 0;
struct sockaddr_in serv_addr;
char send_buff[1024];
int numrv;
listenfd = socket(AF_INET, SOCK_STREAM, 0);
printf("Socket received successfully...");
memset(&serv_addr, '0', sizeof(serv_addr));
memset(send_buff, '0', sizeof(send_buff));
serv_addr.sin_family = AF_INET;
serv_addr.sin_addr.s_addr = htons(INADDR_ANY);
serv_addr.sin_port = htons(50001);
bind(listenfd, (struct sockaddr*)&serv_addr, sizeof(serv_addr));
if(listen(listenfd,10) == -1){
printf("Failed to listen..");
return -1;
}
while(1){
connfd = accept(listenfd,(struct sockaddr*)NULL, NULL);
strcpy(send_buff, "Message from the server");
write(connfd, send_buff, strlen(send_buff));
close(connfd);
