log4net 1.2 RollingFileAppender not working

I'm using log4net v1.2 with a Windows Service App. My RollingFileAppender seems not to work. I'm pasting the logging sections of my service.exe.config below. Can anyone advise where I'm going wrong?

<section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler,log4net"/>

.....(lots of other config stuff)

<appender name="RollingFileAppender" type="log4net.Appender.RollingFileAppender,log4net" >
    <param name="File" value="D:\\Trinity\\Booking\\OneDay_PostTrade\\logs\\Trinity.log" />
    <param name="MaximumFileSize" value="20MB" />
    <param name="MaxSizeRollBackups" value="10" />
    <param name="StaticLogFileName" value="true" />
    <param name="Threshold" value="ALL" />
    <param name="RollingStyle" value="Composite" />
    <param name="appendToFile" value="true" />
    <layout type="log4net.Layout.PatternLayout,log4net">
        <param name="ConversionPattern" value="%d [%t] %-5p %c - %m%n" />
    开发者_高级运维</layout>
</appender>

...(stuff in between)

<root>
    <level value="ALL" />
    <appender-ref ref="ConsoleAppender" />
    <appender-ref ref="RollingFileAppender" />
</root>

.....(stuff in between)

<logger name="CSFB.PostTradeRulesEngine">
    <level value="ALL"/>        
</logger>   

The user your windows service is running as might not have write permission for the log file.
Another possibility is that you forgot to execute XmlConfigurator.Configure();

try writing:

<log4net debug="true">

it will post all errors to console.

thanks to everyone who responded. I dont know what i changed but my logging has started working fine.

Posting my logging sections. I didnt change anything in the code, except a line in the AssemblyInfo.cs: [assembly: log4net.Config.Domain(UseDefaultDomain=true)]

Thanks again.:)
