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%system32inetsrvappcmd 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%system32inetsrvappcmd 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
