Check Procedure

Access the IIS 10.0 Web Server. Access an administrator command prompt and type "regedit <enter>" to access the server's registry. Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\ContentIndex\Catalogs\. If this key exists, then indexing is enabled. If the key does not exist, this check is Not Applicable. Review the Catalog keys to determine if directories other than web document directories are being indexed. If so, this is a finding.

Fix Text

Run MMC. Add the Indexing Service snap-in. Edit the indexed directories to only include web document directories.
