Error Viewing ASP.NET applications After Installing IIS7.5

Question

I get the following error when I try to access a asp.net application on my local machine. Anyone have any ideas?

HTTP Error 500.19 - Internal Server Error The requested page cannot be accessed because the related configuration data for the page is invalid.

Module IIS Web Core Notification BeginRequest Handler Not yet determined Error Code 0x80070021 Config Error This configuration section cannot be used at this path. This happens when the section is locked at a parent level. Locking is either by default (overrideModeDefault="Deny"), or set explicitly by a location tag with overrideMode="Deny" or the legacy allowOverride="false". Config File \?\C:\inetpub\wwwroot\TravelProduct\web.config Requested URL http://localhost:80/TravelProduct/CreateNewQuote.aspx Physical Path C:\inetpub\wwwroot\TravelProduct\CreateNewQuote.aspx Logon Method Not yet determined Logon User Not yet determined

Answer 1

Reinstall your server asp.net for iss using this command:

X:\WINDOWS\Microsoft.NET\Framework\v(.NET Version)\aspnet_regiis.exe -i

This may solve your problem

Answer 2

please check if you deployed your application properly : Deploying an ASP.NET Server (IIS 7)

Answer 3

Please check your web.config file, you must have added some configuration setting which is trying to overwrite the applicationHost.config settings.
