Windows NT 4.0 Pdh.dll PdhExpandCounterPath API Is Incorrect When Used on Windows 2000 (260234)

SYMPTOMS

When the PdhExpandCounterPath() API (ANSI or UNICODE version) is called by using the redistributable Pdh.dll file in Microsoft Windows NT 4.0 (4.0.1314.1) on Windows 2000-based computers, the following output is generated:

\PhysicalDisk/0 C:)\Current Disk Queue Length
\PhysicalDisk/_Total)\Current Disk Queue Length

IMPORTANT: Note that there is a '\' character instead of a ')' character. The same is true for Process, LogicalDisk objects.

When the PdhExpandCounterPathA() API is called by using the %SystemRoot%\system32\Pdh.dll file on a Windows 2000-based computer, no output is generated.

When the PdhExpandCounterPathW() API (UNICODE version) is called by using the %SystemRoot%\system32\Pdh.dll file on a Windows 2000-based computer, the API does not work and generates a C0000BBD.
