我有一个奇怪的错误特定的Windows Server 2008 R2的计算机启动Windows服务时（它与其他的2008 R2机器）上。该服务使用 Common.Logging 和 log4net的。然而，这种特定的机器上不能创造Common.Logging的配置节处理程序。

它失败，出现以下堆栈跟踪（格式为更好的可读性）。最让我惊讶的是 SecurityException异常。是什么原因？

有没有人有一个线索？

解决方案

我已经看到了奇怪的事情发生了，当客户从我们的网站上下载我们的ZIP（ASP.NET应用程序）文件。由于安全功能此文件来自其他计算机，可能被阻止以帮助保护该计算机。

疏通文件解决了所有奇怪的问题，这可以解释为什么这只发生OM的部分的具有完全相同的配置的计算机上。

疏通选项显示只有当文件实际上挡在文件属性对话框的常规选项卡：

I have a strange error on a specific Windows Server 2008 R2 machine (it works on other 2008 R2 machines) when starting a Windows Service. The service uses Common.Logging and log4net. However, on this specific machine the config section handler for Common.Logging can not be created.

It fails with the following stack traces (formatted for better readability). What surprises me most is the SecurityException. What can cause this?

Does anyone have a clue?

    'MyWindowsService.Program' threw an exception.

My configuration looks like this (the Common.Logging part of it anyway).

<configSections>
  <sectionGroup name="common">
    <section name="logging"
             type="Common.Logging.ConfigurationSectionHandler, Common.Logging" />
  </sectionGroup>
</configSections>

<common>
  <logging>
    <factoryAdapter
     type="Common.Logging.Log4Net.Log4NetLoggerFactoryAdapter,Common.Logging.Log4net">
      <arg key="configType" value="INLINE" />
    </factoryAdapter>
  </logging>
</common>

I've seen strange things happening when customers downloaded our zip (ASP.NET application) file from our website. Because of the security feature "This file came from another computer and might be blocked to help protect this computer".

Unblocking the files solved all strange problems, this would explain why this is only happening om some computers with exactly the same configuration.

The Unblock option is shown only when the file is actually blocked in the General tab of the file properties dialog:
