FTP logging cannot display the physical path for any FTP command issued by users of an IIS FTP server

Applies to: Internet Information Services 8.5Internet Information Services 8.0Windows 8 More

Symptoms


FTP logging cannot display the physical path for any FTP command issued by users of an Internet Information Services (IIS) FTP server. This behavior makes it difficult to debug the FTP server issues especially in multi-tenant scenarios for different problems including security and access failures.

Cause


This behavior occurs because the physical path is not available as a field for logging while setting up FTP Server logging.

Resolution


After you apply this hotfix, you can specify the physical path as a field when you set up logging for an IIS FTP server for debugging. To do this, follow these steps:
  1. Run Inetmgr.exe to start the Internet Information Services (IIS) Manager.
  2. Select the Computer node in the navigation pane's tree view control.
  3. Double-click the Configuration Editor icon in the Management pane to open the Configuration Editor page.
  4. Select system.applicationHost/sites in the Section: drop-down combo box.
  5. Select the Collectionname and then click the ellipsis () button, click ftpServer\logFile\logExtFileFlags and then click one of the following:
    • To select the PhysicalPath for all sites, select siteDefaults\ftpServer\logFile\logExtFileFlags.
    • To select a specific site, select the site by Instance ID. 
Note This same process can be made from system.ftpServer\log\centralLogFile\logExtFileFlags for the FTP server level.

More Information


The ability to log the physical path is provided to ease debugging problems by FTP Server administrators and should be disabled after the debugging is finished. Failure to do this makes the FTP server unusable and may cause other issues generally if the hotfix is uninstalled from the computer. For FTP server administrators to take advantage of physical path logging capabilities, this hotfix updates the schema that the applicationHost.config file on the computer validates the settings against. Removal of the hotfix will restore the FTP configuration schema to the version before the update. This makes any configuration changes that takes advantage of the new physical path field invalid.
