IIS Not working

I have a web site that built on Visual studio 2008 and

i need to run it from my computer (Win 7 Ultimate) as a server

I tried to publish it to IIS and this is simply not working and i have the flowing error :

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

Config Error This configuration section cannot be used at this path. This happens when the section is locked at a p开发者_JS百科arent level. Locking is either by default (overrideModeDefault="Deny"), or set explicitly by a location tag with overrideMode="Deny" or the legacy allowOverride="false".

any one can help?

It looks like the Web.config file contains some disallowed section. Some sections can only be set in the machine-wide configuration, some can only be set at the root of a web site, etc.

Simplify your web.config as much as possible (make it as empty as possible) and when the page displays, add one section at a time.

Silly problem but IIS never warn about it
i have missed installing the component (from control panel) that support ASP.NET when i installed it ,it worked :)
