You can try to unlock it in applicationhost.config like this
<configSections>
  <sectionGroup name="system.webServer">
    <section name="handlers" overrideModeDefault="Allow" /> 
Or remove the section which caused the error
<remove name="WebServiceHandlerFactory-Integrated" />


Also, You can change the section modules to unlock it according to the error messages, like:
<section name="modules" allowDefinition="MachineToApplication" overrideModeDefault="Allow" />
Or you can unlock in IIS by selecting server name and in right side configuration editor unlock the section.
