Exchange ActiveSync tracing is currently enabled
[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. By following these recommendations, you can achieve better performance, scalability, reliability, and uptime. For more information about the tool or to download the latest versions, see "Microsoft Exchange Analyzers" at http://go.microsoft.com/fwlink/?linkid=34707.]

The Microsoft® Exchange Server Analyzer Tool reads the following registry entry to determine if tracing has been enabled for Exchange ActiveSync®:
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\Tracing\Microsoft Server ActiveSync\MasSync\Enabled
If the Exchange Server Analyzer finds the value for Enabled is present and configured with a value greater than 0, a warning is displayed.
Exchange ActiveSync is implemented as an Internet Server Application Programming Interface (ISAPI) extension in Internet Information Services (IIS). IIS, Exchange ActiveSync, and many of the client devices that use Exchange ActiveSync include native tracing capabilities, thereby obviating the need to use the native tracing capabilities of Microsoft Windows Server™ 2003.
