TextWriterTraceListener in app.config executing over a NetworkShare causes FileIOPermission exception

I am at a loss as to why this is not working. I am trying to setup a
TextWriterTraceListener in my application config file and then execute the
app from the network. I get a security exception (listed below) even though
I have StrongNamed my application and used the .NET Configuration Tool to
create a Code Access Group in the Machine Policy that gives FullTrust to
assemblies with the StrongName that I created.

If you uncomment the code in Main and remove the <system.diagnostics> from
the app.config it will run without error.


I did a "net use Y: \\computer\share" to setup my execution location.

I am wondering if this is just a bug with .NET or I need to find the magic
setting somewhere to get things to work...

Please help.
