I am installing ASP.NET application for a new customer. As a test,
I am asking them to run a very simple TEST.ASPX page which has no
code but simply displays a static text. And we cannot make this
page to show.

The error message we (the customer) is getting is as following:

Parser Error Message: it is an error to use a section registere as 
allowDefinition='MachinteToApplication' beyound application level. 
This error can be caused by a virtual directory not being 
configured as an application in IIS.

The error then points to the following line in web.config:

<authentication mode="None" />

We tried to change the mode to Windows but still the same result.

I checked the properties of the virtual directory (talking to the
customer on the telephone), and they all seem to be the same as I
have on my PC.


What else can we check for this error?

Thank you.
