TMS HTTP Error 500.19 - Internal Server Error

Hi Experts


We recently installed the TMS 14.2.1 on windows 2012 R2 and we are try to open the TMS application server but the page is not loaded and we are getting below error message. Can you guide me how to resolve this issue


HTTP Error 500.19 - Internal Server Error

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

Detailed Error Information:

Module   IIS Web Core
Notification   BeginRequest
Handler   Not yet determined
Error Code   0x80070021
Config Error   This configuration section cannot be used at this path. This happens when the section is locked at a parent level. Locking is either by default (overrideModeDefault="Deny"), or set explicitly by a location tag with overrideMode="Deny" or the legacy allowOverride="false".
Config File   \\?\C:\Program Files (x86)\TANDBERG\TMS\wwwtms\web.config



Thanks & Regards
