log4Net EventlogAppender不适用于Asp.Net 2.0 WebSite？

<log4net>
    <appender name="EventLogAppender" type="log4net.Appender.EventLogAppender">
      <param name="LogName" value="Test Log" />
      <param name="ApplicationName" value="Test-Web" />
      <layout type="log4net.Layout.PatternLayout">
        <conversionPattern value="%date [%thread] %-5level %logger [%property{NDC}] - %message%newline" />
      </layout>
    </appender>
    <root>
      <priority value="ERROR"/>
      <appender-ref ref="EventLogAppender"/>
    </root>
    <logger name="NHibernate">
      <level value="ERROR" />
      <appender-ref ref="EventLogAppender" />
    </logger>
  </log4net>

我已经创建了测试日志事件日志,AspNet用户具有事件日志注册表项的权限.我还在Global.asax Application_Start中配置了log4Net.

log4net.Config.XmlConfigurator.Configure();

更新：我打开了log4net内部调试,并在跟踪中发现以下错误.

log4net:ERROR XmlHierarchyConfigurator: Could not create Appender [EventLogAppender] of type [log4net.Appender.EventLogAppender]. Reported error follows.
System.Security.SecurityException: The source was not found,but some or all event logs could not be searched.  Inaccessible logs: Security.
   at System.Diagnostics.EventLog.FindSourceRegistration(String source,String machineName,Boolean readOnly)
   at System.Diagnostics.EventLog.SourceExists(String source,String machineName)
   at System.Diagnostics.EventLog.SourceExists(String source)
   at log4net.Appender.EventLogAppender.ActivateOptions()
   at log4net.Repository.Hierarchy.XmlHierarchyConfigurator.ParseAppender(XmlElement appenderElement)

更新2：如果我在c#中使用基于控制台的应用程序创建事件源(Test-Web),然后使用Web应用程序,它将最终起作用.
