Impersonation and Custom Event Log - write access denied

[JimLad]

Hi,

I have created a Custom Event Log. My ASP.NET application is
impersonating a specific Windows Account that currently has no
permissions on the web server, apart from Modify access to C:\WINDOWS
\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files.

I cannot currently write to the event log. I am using the Logging
Application Block.

What is the best practice way of writing to the event log when using
impersonation? I'd like to do this from within ASP.NET if possible and
I want to avoid raising permissions as far as possible.

Cheers,

James
