[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.

The Microsoft® Exchange Server Analyzer Tool reads the following registry entry to determine the version of Microsoft Windows® running on the server that is running Exchange Server:

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\CurrentVersion

A CurrentVersion value of 4.0 indicates that the Exchange server is running Microsoft Windows NT® Server 4.0. A value of 5.0 indicates that the Exchange server is running Windows 2000 Server. A value of 5.2 indicates the Exchange Server computer is running Windows Server™ 2003.

The Exchange Server Analyzer also examines the Win32_Processor Windows Management Instrumentation (WMI) class to determine the value for the DataWidth key.

A DataWidth key value of 32 indicates the server is running a 32-bit version of the Windows operating system whereas a DataWidth key value of 64 indicates the server is running a 64-bit version of the Windows operating system.

Finally, the Exchange Server Analyzer queries the CIM_Datafile WMI class to determine the value of the Version key for a file that is named CpqCiDrv.sys.

The Exchange Server Analyzer displays an error if the following conditions are true:

  • The Exchange server is running Windows Server 2003.

  • The Exchange server is running a 64-bit version of the Windows operating system.

  • The version of the HP Integrated Lights-Out Management Interface driver, CPQCIDRV.sys, is earlier than 1.8.

This error indicates that the version of CpqCiDrv.sys installed on the server may cause kernel memory allocation errors.

To resolve this problem, follow the guidance of the vendor in Document ID: c00688313 (http://h20000.www2.hp.com/bizsupport/TechSupport/Document.jsp?objectID=c00688313).
