[This topic is intended to address a specific issue called out by the Exchange Server Analyzer Tool. You should apply it only to systems that have had the Exchange Server Analyzer Tool run against them and are experiencing that specific issue. The Exchange Server Analyzer Tool, available as a free download, remotely collects configuration data from each server in the topology and automatically analyzes the data. The resulting report details important configuration issues, potential problems, and nondefault product settings.

The Microsoft Exchange Best Practices Analyzer searches the Internet Information Services (IIS) metabase to enumerate the Microsoft-Server-ActiveSync virtual directories. The Best Practices 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.
