Try removing your line: <logName value="Application"/>
I think what you're doing there is naming a custom EventLog with the same name as the existing Application log, which in turn requires write access to the registry. Just remove that line and see what happens. -BillyB WILLIAM BARNUM [EMAIL PROTECTED] ________________________________________ From: Matthew Brown [mailto:[EMAIL PROTECTED] Sent: Monday, October 10, 2005 1:43 PM To: Log4NET User Subject: Inability to use EventLogAppender with ASPNET With log4net internal debugging turned on, an attempt to create an EventLogAppender for a web application is failing: [3616] log4net: XmlHierarchyConfigurator: Setting Property [Layout] to object [log4net.Layout.PatternLayout] [3616] log4net: XmlHierarchyConfigurator: Setting Property [LogName] to String value [Application] [3616] log4net:ERROR XmlHierarchyConfigurator: Could not create Appender [EventLog] of type [log4net.Appender.EventLogAppender].

Just to be sure, I made sure to add ASPNET and IUSR_machinename to the Administrators group, but this does not work either. Here is my configuration: <appender name="EventLog" type="log4net.Appender.EventLogAppender" > <layout type="log4net.Layout.PatternLayout"> <conversionPattern value="%date [%thread][%mdc{AspNetSessionID}] %-5level %logger - %message%newline" /> </layout> <logName value="Application"/> </appender> <root> <level value="ALL" /> <appender-ref ref="LogFileAppender" /> <appender-ref ref="EventLog" /> </root> Sorry if this is a silly newbie question, but I couldn't find much out there on configuring/using EventLogAppender besides "its tough". Can anyone help? Thanks, Matt Brown
