The Microsoft® Exchange Server Analyzer Tool queries the Win32_OperatingSystem Microsoft Windows® Management Instrumentation (WMI) class to determine the value for the PAEEnabled key. The value of this key indicates whether Physical Address Extension (PAE) is enabled. A value of True indicates that PAE is enabled, and a value of False indicates that PAE is not enabled. The Exchange Server Analyzer also queries the Win32_OperatingSystem WMI class to determine the value for the MaxProcessMemorySize key.
If the Exchange Server Analyzer finds the value of PAEEnabled equal to True and the value for MaxProcessMemorySize to be greater than 2097024, a warning is displayed. This warning indicates that these values are not the default values. The Exchange Server Analyzer reports this configuration for informational purposes only. No action is required.
