File logging in ASP.NET on Win2003 / IIS6 - Tip

[Thomas Koch <th...@yahoo.dk>]

Hi all - I thought I'd share my experiences when using
log4net in an ASP.NET application on IIS 6.0

When using any of the file appenders from an ASP.NET
IIS 6.0 will prevent the ASP.NET application from
writing to the log file unless the process driving the
application has write access to the directory in
question.

On WinXP / IIS 5.x it is usually enough to simply
allow the user running the ASP.NET work process to
have write access to the directory.

On IIS 6.0 this does not work. You need to give the
write access to the process running the Application
Pool of the ASP.NET - this is usually the "NETWORK
SERVICE" process. You can see the process name under
the properties tab for the application pool.

Maybe this is a good candidate for a FAQ.

Thanks for a nice logging framework.

Cheers
Thomas
