about the error and where it originated in the code. 

Exception Details: System.UnauthorizedAccessException: Access is denied. 

The ASP.NET process is not authorized to access the requested resource. 
For security reasons the default ASP.NET process identity is '{machinename}
\ASPNET', which has limited privileges. Consider granting access rights to 
the resource to the ASP.NET process identity. 

To grant ASP.NET write access to a file, right-click the file in Explorer, 
choose "Properties" and select the Security tab. Click "Add" to add 
the "{machinename}\ASPNET" user. Highlight the ASP.NET account, and check 
the Write box in the Allow column.
