Server Error in '/NES' Application.
----------------------------------------------------------------------------
----

Access to the path "c:\inetpub\wwwroot\Projects" is denied.
Description: An unhandled exception occurred during the execution of the
current web request. Please review the stack trace for more information
about the error and where it originated in the code.

Exception Details: System.UnauthorizedAccessException: Access to the path
"c:\inetpub\wwwroot\Projects" is denied.

ASP.NET is not authorized to access the requested resource. Consider
granting access rights to the resource to the ASP.NET request identity.
ASP.NET has a base process identity (typically {MACHINE}\ASPNET on IIS 5 or
Network Service on IIS 6) that is used if the application is not
impersonating. If the application is impersonating via <identity
impersonate="true"/>, the identity will be the anonymous user (typically
IUSR_MACHINENAME) or the authenticated request user.

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
appropriate user or group. Highlight the ASP.NET account, and check the
boxes for the desired access.

Hi NagaKiran,

In windows application the application works in a account
of login user. Mostly login user has permission of full
control to operating computer. On the other hand, the web
application works in a special account, ASPNET. If you
don't give the account permissions to access, create, or
delete, when conduct those kinds of opertions it will
cause UnauthorizedAccessException.

Hope it helps,
