After deploying WCF services in a win2008+iis7.5 environment today, pages that cannot be opened are always present. The specific error message is as follows:

The requested page cannot be accessed because the related configuration data for the page is invalid.

The most probable cause:
The worker process could not read the ApplicationHost.config or Web.config file.
Malformed XML exists in the ApplicationHost.config or Web.config file.
The server cannot access applicationhost.config or Web.config files because NTFS permissions are incorrect.
Actions you can try:
Query the event log for information about why the configuration file is not readable.
Ensure that the user identity specified for the application pool or authenticated user has the necessary permissions to access the Web.config file.
Search on the internet for a long time, found that are not matching errors. Finally found in an English-language website.
