  • Netwrix Auditor 6.5 and below: Settings -> Audit Archive

  2. Review available reports:
  • IIS Changes of Application Pools—shows changes in Application Pools, such as adding, deleting, renaming Application Pools, changing their properties, starting, stopping, etc.
  • IIS Changes of Web Sites—shows changes in Web Sites, such as creating, deleting, renaming, starting and stopping Web Sites, changing their general properties, changing the Binding options: creation, deletion, modification, etc.


  1. Netwrix Auditor  for Event Log audits event-based changes. If the target servers lose events for some reason or Netwrix Auditor is not able to collect these events, reports will not contain configuration changes.
  2. The Internet Information Services (IIS) configuration changes made directly in the configuration files and not through the IIS Manager will never be logged in the IIS Operational log  and reported by Netwrix Auditor.
