Orchestrator functionality can be impaired if the <system.webServer> element in web.config contains any locked sections. The UiPath Platform Configuration Tool checks the <system.webServer> element for any locked sections. If such sections exist, you need to manually unlock them in IIS.

Unlocking web.config Sections in IIS

1. In IIS, select the Orchestrator machine.
2. In the Management section, double-click Configuration Editor. The Configuration Editor window is displayed.

3. From the Section drop-down, expand system.webServer and select the section you want to unlock.
4. On the right-hand Actions pane, Section element, click Unlock Section.
