System.Runtime.InteropServices.COMException功能不正确。 （HRESULT异常：0x80070001）

Question

我在ASP.net中有一个Asynchronus IHttpHandler，我在ELMAH捕获中看到了这个异常错误。

Windows Server 2008 R2网络版 IIS 7.5 ASP.NET .NET 4.0运行时 在网站上运行HTTP。

有人能对这一个有所了解吗？谷歌在2008年左右列出了一些关于.NET 2.0中关于在请求体的Read（）函数期间断开HTTP连接的错误的结果。

Answer 1

这是由IIS7的基础非托管层（webengine.dll）报告的错误。经过一些谷歌搜索后，最相关的线程似乎表明这是一个错误，因为网卡驱动程序配置（TCP Offloading）。
