This is probably not a problem with SiteCore as such, but I have included it for completeness. I have sitecore 6.3 running under IIS7 using a user id for the application pool. I cannot get Sitecore to write log information (using the default log4net settings) to the event log. I went for advice here: http://logging.apache.org/log4net/release/faq.html#Why%20doesn%27t%20the%20EventLogAppender%20work? , and although it works great when I make an individual identifier a member of the admin group, I need to find a way to make it work in production without such a security hack.
It is strange that I have an MSI that installs it (runs under an account that is a member of the administrators group) and creates the correct registry keys for me in the event log, but despite this, I still get an error after starting the application with using a user identity (without his membership in administrators).
log4net:ERROR DOMConfigurator: Could not create Appender [EventLogAppender] of type [log4net.Appender.EventLogAppender]. Reported error follows.

The Zone of the assembly that failed was:

log4net:ERROR DOMConfigurator: Appender named [EventLogAppender] not found.
I think I could narrow it down to the issue of register permission. I granted everyone full access rights to the following registry key and subkeys, but it did not work either:HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\eventlog
The user identifier is a member of the following groups:
- Event Logs
- IIS_USERS
- Performance Monitor Users
