The Microsoft® Exchange Server Analyzer Tool includes a performance data collection engine that is used to query performance counter objects on computers that are running Exchange 2000 Server or Exchange Server 2003. The performance data collection engine collects data from multiple performance counters of the Processor performance object to analyze performance data.

The Exchange Server Analyzer also queries the CIM_Datafile Microsoft Windows® Management Instrumentation (WMI) class to determine the value that is set for the Version key of the Msgtrak.dll file.

The Exchange Server Analyzer displays a warning if the following conditions are true:

  • The server is experiencing high CPU usage.

  • The value of the Version key for the Msgtrak.dll file is earlier than 6.0.6373.0.

This warning indicates that the version of Msgtrack.dll found can potentially cause the high CPU usage. The warning also indicates that the version of Msgtrack.dll found may cause the Inetinfo.exe process to show very high memory use.

To address this issue, obtain the update referenced by Microsoft Knowledge Base article 811409, "XADM: Message Tracking May Cause the Inetinfo.exe Process to Show Very High Memory Use" (
