Log4Net Not Logging When Deployed

Question

Using version 1.2.11. Logging works on my dev machine, but won't create the directory or log when deployed.

I tried:

• giving full directory access to IUSR, Everyone, local users.
• running the app pool as a local admin account.
• to use internal debugging as Phil Haack describes here.

Stopped and started the app pool after each change.

Nothing is produced in the output file.

My log4Net config is below. Any thoughts on what to try next?

<?xml version="1.0"?>
<log4net debug="true">
  <appender name="file" type="log4net.Appender.RollingFileAppender">
    <file value="..\Logging\log.txt" />
    <appendToFile value="true" />
    <rollingStyle value="Composite" />
    <datePattern value="yyyyMMdd" />
    <maxSizeRollBackups value="10" />
    <maximumFileSize value="1MB" />
    <threshold value="DEBUG" />
    <layout type="log4net.Layout.PatternLayout">
      <conversionPattern value="%date [%thread] %-5level %logger [%property{NDC}] - %message%newline" />
    </layout>
  </appender>
  <appender name="console" type="log4net.Appender.DebugAppender">
    <layout type="log4net.Layout.PatternLayout">
      <param name="ConversionPattern" value="%d [%t] %-5p %c [%x] &lt;%X{auth}&gt; - %m%n" />
    </layout>
  </appender>
  <root>
    <level value="ALL" />
    <appender-ref ref="file" />
    <appender-ref ref="console" />
  </root>
</log4net>

If you're using IIS, make sure the correct group has modify access to the Logs folder (usually IIS_USERS).
