Startar site on IIS is returning error 500

Question

Trying to learn how to set up a site on IIS, by typing the site URL, this gives the following error:

Server Error

500 - Internal server error. There is a problem with the resource that you are looking for and it cannot be displayed.

I wonder what might be going on. I call the site by IP: 192.168.0.103 from my note book and the IIS is on my Desktop in another compartment of the house. The network is wireless, with only two points. Note and Desk.

Man web.config is in the default setting, no modifications.

See what I changed on IIS to solve the problem.

By selecting the option in the combo section to unlock, already gives this error

Answer 1

The actual error you are getting as your screenshot is:

This configuration section cannot be used in this path. This occurs when the section is locked on a parent level. Lock is by default (overrideModeDefault="Deny"), or is explicitly defined by a local tag with overrideMode="Deny" or the inherited allowOverride="false".

This error is happening because the web.config of its application, located in c:\Inetglobal\Site\web.config is trying to override module settings (system.WebServer\modules) IIS, which is locked for editing in lower level . config files. To get around the error, do the following:

• Open the IIS Manager
• In the treeview on the left, click on the server (usually the name of your computer)
• On the main panel, click Settings Editor (Configuration Editor)
• In the combo of Sections (Sections), select the section giving error (system.webserver/modules)
• In the right pane (Actions or Actions), click on Unlock Attribute (Unlock Attribute)
• If an error occurs in another section repeat the last two steps for it
• Restart the OSI
