>                 URL: https://issues.apache.org/jira/browse/LOG4NET-506
>             Project: Log4net
>          Issue Type: Bug
>          Components: Appenders
>    Affects Versions: 1.2.15
>         Environment: Windows Server 2008 R2, Windows Server 2012 R2
>            Reporter: Frédéric Delaporte
>            Priority: Minor

> Many applications run on the same server.
> Some are windows services running under "Local system" identity, others are IIS hosted
web sites running under "Application pool" identity.
> All do log through {{RollingFileAppender}} to {{D:\Logs\}} (value of {{file}} configuration
node) to their own file log (filename specific to each application through {{datePattern}}
configuration node).
> They log through {{AdoNetAppender}} too.
> Since having upgraded Log4Net from 1.2.13 to 1.2.15 on all services and some web sites,
upgraded IIS web sites cease being able to log to {{D:\Logs\}}. SQL logs still work. Non upgraded
web site are still able to log to {{D:\Logs\}}.
> The services start before the web sites.
> Stopping all services then restarting a web site allows it to log again in {{D:\Logs\}}.
Restarting a second web site (having a different application pool) while the first is still
running does not allow the second one to log again in {{D:\Logs\}} (Application pool identity
give different identity to each pool).
> Activating log4net debug trace on a web site, and comparing failure cases to working
cases, yields following diff:
