The Microsoft® Exchange Server Analyzer Tool reads the following registry key to determine whether Microsoft Windows® Server 2003 is installed: HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\
The Exchange Server Analyzer also performs the following queries:
- The Win32_OperatingSystem Microsoft Windows Management
Instrumentation (WMI) class to determine whether Windows Server
2003 Service Pack 1 is installed.
- The Win32_Service WMI class to determine whether Cluster
service is running.
- The Win32_Volume WMI class to determine whether there
are Volume Mount Points present.
- The CIM_Datafile WMI class to determine whether the
value of the Version key for Mountmgr.sys is less then
The Exchange Server Analyzer displays an error if the following conditions are true:
- The Version key for Mountmgr.sys is less then 2443.
- The server is a node of a Cluster running Windows Server 2003
Service Pack 1.
- The server has volume mount points.
The version of Mountmgr.sys installed on the cluster node may cause volume mount point failures. This problem occurs because of a problem in the Mountmgr.sys driver. This is an intermittent timing problem that can occur when a volume arrives to be mounted to a mount point.
|Generally, this problem does not occur in a non-clustered environment. In a non-clustered environment, the timing of the volume mount process is different.|
