I had this issue in smbwrapper as well.  After some discussion with people on
this list, I came to the following solution which has worked well for me so

        /* Force use of port 139 for first try, so browse lists can work*/
        c.port = 139;
        /* Attempt to connect */
        if (!cli_connect(&c, server_n, &ip)) {
                 * Port 139 connection failed.  Try port 445 to handle
                 * connections to newer (e.g. XP) hosts with NetBIOS disabled.
                c.port = 445;
                if (!cli_connect(&c, server_n, &ip)) {
                        errno = ENOENT;
                        return NULL;
