iis7/iis7.5 HTTP Error 500.19 configuration error Unable to read configuration file resolution due to insufficient permissions _win server

Win7 Web development problems-Unable to access the requested page because of insufficient permissions to read the configuration file

Error One:
HTTP Error 500.19-internal Server error
Configuration error: This configuration section cannot be used in this path. This can occur if the section is locked at the parent level. The lock is set by default (overridemodedefault= "Deny"), or is explicitly set by a location tag that contains overridemode= "deny" or the old allowoverride= "false".

This error occurs because IIS 7 uses a more secure Web.config management mechanism, and locks the configuration entry to disallow changes by default. To unlock, you can run the command line%windir%\system32\inetsrv\appcmd unlock config-section:system.webserver/handlers. The handlers is the name of the node in the error message that appears in the red Word.

If the modules is also locked, you can run%windir%\system32\inetsrv\appcmd unlock config-section:system.webserver/modules
In addition, if the use of ASP.net friends, in the installation of IIS7 must remember to check asp.net, the default is not selected, there will be similar error message

Error Two:

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