At the bold part where the crashing happens at only one time at a specific value,

 void GetHostIP()
{
    char *Ip;
    WSADATA wsaData;

    struct sockaddr_in tmpSockAddr; //placeholder for the ip address

    // Not needed if it is already taken care by some other part of the application
    WSAStartup(MAKEWORD(2,0),&wsaData); 

    char hostname[25];
    strcpy(hostname,"Test Computer Name")
    //This will retrieve the ip details and put it into pHostEnt structure
    pHostEnt = gethostbyname(hostname);

    if(pHostEnt == NULL)
    {
        printf("Error occured: %s\n",GetLastError());
        return;
    }

    memcpy(&tmpSockAddr.sin_addr,pHostEnt->h_addr,pHostEnt->h_length);

    Ip = NULL;
    Ip = new char[17];
    strcpy(Ip,inet_ntoa(tmpSockAddr.sin_addr));
    printf("Ip Address of the machine %s is %s\n",Ip);

    // Not needed if it is already taken care by some other part of the application
    WSACleanup();
    delete [] Ip;
}

Somethings seem HARD to do, until we know how to do them.
