Some 32-bit performance counter objects have NOT been implemented in Windows Server 2003 for Itanium-based systems. The 32-bit Windows sub-system, WOW64, does not have corresponding 32-bit versions of all 64-bit performance counters.
To find out if a 32-bit version of a performance counter object is implemented for Windows Server 2003 for Itanium-based systems:
1. Open a CMD.EXE window.
2. Type the following commands, pressing Enter after each line:
cd /d %SystemRoot%\SysWow64
copy %SystemRoot%\System32\Perfmon.msc *.*
mmc.exe /32 perfmon.msc
3. If a performance counter object does NOT appear, but it is available when you run System Monitor normally, it is NOT implemented as a 32-bit version.
