IIS Polling Failed

Error: Application polling failed because IIS information is currently unavailable.

Cause: This is a general error message returned by Windows when a networking component is malfunctioning.

Resolution: For details, see the log on the Orion server located at: [ALLUSERSPROFILE]\ProgramData\Solarwinds\Logs\APM\RemoteExecutableStarter.log. Restart the remote registry service, check that TCP port 445 is open between the Orion server and the remotely monitored IIS server. When complete, rerun the AppInsight for IIS Automatic Configuration Wizard.
