这个问题其实和之前遇到过的IIS服务器上无法识别svg/woff/woff2字体一样，都是IIS没有注册MIME类型导致的。解决方法也一样，先确认文件已经上传并且路径配置正确，然后远程登录主机，打开IIS，找到网站，右键属性，打开“HTTP头”，找到右下角的“MIME类型…”，添加对应的MIME类型即可：
.3gp 3gp video/3gpp
.flv application/octet-stream
.mp4 application/octet-stream
在不提供远程登录权限的虚拟机下，如果是IIS7和IIS8以上版本，可以编辑网站根目录下的web.config，在<staticContent>区域内增加这样几条：
保存上传，服务器就支持这些格式了
这里附上别处找来的MIME类型大全：

webconfig添加 节点的技巧 MIME映射
IIS配置中，.lrc类型的文件默认无法访问，所以个人在IIS7.5的mime类型中增加了.lrc的类型的支持，但问题是需要每台机器中增加这些设置，不利于团队协作，于是，只好将这些修改体现在代码上，具体实现方式为：
在站点的web.config中增加了
修改后一直正常运行。
前不久本人的电脑C盘空间不足，折腾多次后，无奈格盘重装，分给C盘很大的空间，系统也改为64位。今日重新运行该网站，即报错：
配置错误: 在唯一密钥属性“fileExtension”设置为“.lrc”时，无法添加类型为“mimeMap”的重复集合项。
怪的是代码现在仍在他人机器上正常运行，所以百度寻求答案。有云IIS应用程序池如果是集成模式，改为经典模式即可，但尝试后没有效果。
这时候才想起来自己解决，看说明，似乎是扩展名的设置重复了嘛。于是删除该段配置，发现程序正常运行，且对于.lrc文件仍旧支持。
原来是IIS7.5默认的文件扩展支持增多了，而且，更可恶的是百度到的各种解释，竟然没有一个说这种解决方法的。
不过，为了与大家的一致，这里加了一段多余的配置：
扩充 staticContent 节点，让 IIS 看的懂 HTML5 Video 与 WebFont
如果需要使用到 HTML5 的Video Tag 播放影片需要以下設定：
<span style="background-color: rgb(255, 255, 255);"><system.webServer> <staticContent> <remove fileExtension=".mp4" /> <remove fileExtension=".ogv" /> <remove fileExtension=".webm" /> <remove fileExtension=".svg" /> <mimeMap fileExtension=".mp4" mimeType="video/mp4" /> <mimeMap fileExtension=".ogv" mimeType="video/ogg" /> <mimeMap fileExtension=".webm" mimeType="video/webm" /> <mimeMap fileExtension=".svg" mimeType="image/svg+xml" /> </staticContent> </system.webServer></span>如果需要使用到 Web font 需要以下設定：
<span style="background-color: rgb(255, 255, 255);"><system.webServer> <staticContent> <remove fileExtension="<span style="margin: 0px; padding: 0px; border: 0px; font-family: inherit;font-size:undefined; font-style: inherit; font-variant: inherit; line-height: inherit; vertical-align: baseline;">.woff</span>" /> <remove fileExtension=".svg" /> <remove fileExtension="<span style="margin: 0px; padding: 0px; border: 0px; font-family: inherit;font-size:undefined; font-style: inherit; font-variant: inherit; line-height: inherit; vertical-align: baseline;">.eot</span>" /> <remove fileExtension=".ttf" /> <remove fileExtension=".otf" /> <mimeMap fileExtension="<span style="margin: 0px; padding: 0px; border: 0px; font-family: inherit;font-size:undefined; font-style: inherit; font-variant: inherit; line-height: inherit; vertical-align: baseline;">.woff</span>" mimeType="application/x-woff" /> <mimeMap fileExtension=".svg" mimeType="image/svg+xml" /> <mimeMap fileExtension="<span style="margin: 0px; padding: 0px; border: 0px; font-family: inherit;font-size:undefined; font-style: inherit; font-variant: inherit; line-height: inherit; vertical-align: baseline;">.eot</span>" mimeType="application/vnd.ms-fontobject" /> <mimeMap fileExtension=".ttf" mimeType="application/x-font-ttf" /> <mimeMap fileExtension=".otf" mimeType="application/x-font-opentype" /> </staticContent> </system.webServer></span>window2012 IIS8 配置网站下载exe文件。解决window2012 IIS8 配置的网站无法下载exe文件的问题
配置好网站后，无法下载网站上的exe文件，zip文件确可以下载的。右键点击EXE文件链接选择另存为后，提示文件无法下载。
在服务器的浏览器里直接打开exe链接的时候提示
“HTTP错误 404.2-Not Found"
由于Web服务器上的"ISAPI和CGI限制”列表设置，无法提供您请求的页面
解决方案很简单：
打开IIS8-->打开网站或虚拟目录--->功能视图里面“处理程序映射”-->右键菜单“编辑功能权限”-->权限里面移除“执行”，只保留“读取”和“脚本”两个复选框-->重启IIS
事实上这就是IIS7版本以前的【设置目录执行权限】
有两种
分别用<bgsound>和<embed></embed>标签,当用<embed>插入背景音乐时可以设置宽度和高度为0，隐藏播放器。
二者的参数如下：■ <bgsound>：
<bgsound> 是用来插入背景音乐，但只适用于 IE，其参数设定不多。如下
<bgsound src="your.mid"autostart=true loop=infinite>
src="your.mid"
设定 midi 档案及路径，可以是相对或绝对。
autostart=true
是否在音乐档下载完之后就自动播放。true 是，false 否 (内定值)。
loop=infinite
是否自动反复播放。LOOP=2 表示重复两次，Infinite 表示重复多次。■ <EMBED>：
<EMBED> 是用来插入各种多媒体，格式可以是 Midi、Wav、AIFF、AU 等等，Netscape 及 新版的 IE 都支持。其参数设定较多。如下下
<EMBED src="your.mid"autostart="true" loop="true" hidden="true">
