The Microsoft Exchange Server Best Practices Analyzer searches the Internet Information Services (IIS) metabase to enumerate the Microsoft-Server-ActiveSync virtual directories. The Best Practice Analyzer verifies that the EnableDirBrowsing flag in the DirBrowseFlags metabase property is set to False for each Microsoft-Server-ActiveSync virtual directory.

If the EnableDirBrowsing flag is not set to False, the Best Practices Analyzer generates the following message:

The '{4}' option of virtual directory '{3}' on server {2} is enabled. It is recommended to disable it.

To resolve this issue, disable directory browsing on the Microsoft-Server-ActiveSync virtual directories.

To disable directory browsing on the Microsoft-Server-ActiveSync virtual directory in IIS 6.0

  1. Start Internet Information Services (IIS) Manager.

  2. In the Connections pane, expand the server node, expand Sites, expand Default Web Site, right-click Microsoft-Server-ActiveSync, and then click Properties.

  3. On the Virtual Directory tab, click to clear the Directory browsing check box, and then click OK.

  4. At a command prompt, run the iisreset command to reset IIS.
