Hello
I've just developed an application in VS on my machine (w2k), c#.
Everything worked just fine, but when i installed the web application on the
company server (w2k3 server), everything worked still fine exept writing back
into an xml file!
The file i want to write to is stored in a dir. in the inetpub folder.

I've been looking around on the internet for a long time now, but NOTHING
worked!
 - I gave full trust in the .NET configuration (and tried much more)
 - added the ASPNET user
 - checked the machine.config

I admitt the whole .net security stuff is verry new to me but i think i
tried all the standart stuff.

I'd be so glad if someone could help me out here!

I will also post the exception that is thrown:
