When attempting to view Production Terminal on IIS7/Windows Server 7, you receive:

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

The %windir%\System32\inetsrv\config\applicationHost.config file is locking configuration nodes in the Production Terminal's WebSite's web.config.

Open the applicationHost.config and find the node. If it contains:

overrideMode=“Deny”

Change it to:

overrideMode=“Allow”

Repeat these changes for the node as well.

If neither of these nodes have an overrideMode value, read upward from where it should be until you find overrideModeDefault and set it to “Allow”.
