LoadRunner 9.1 测试MMS流媒体遇到的问题

ww-nlc

我用 LoadRunner9.1 测试MMS流媒体时，脚本是在网上找的，如下：
        mms_play( "test1.wmv",
                "URL=mms://xxx.xxx.xxx.xxx/2010-LE-00003/test1.wmv",
                "duration=-1",
                "starttime=0",
                LAST );

        mms_close();
        return 0;

wmload.asf文件也已经拷到了服务器发布点的根目录，回放时不再报 wmload.asf 找不到的错误。
现在的问题是脚本回放时，流媒体服务器那边的“已连接的客户端数”不发生变化，一直是零，应该是没连上，可是日志中看不出什么异常，日志如下：

请高手帮忙看看是什么原因，到底连上了没有？
