Where can i find pdh.dll (performance Data Helper) for Win 2K3 ser

I want a pdh.dll (or a perfmondata.dll) file that would work on a Windows

Server 2003 platform. I need to access some performance counters of a custom

application, which are listed under perfmon. They can be captured using the

APIs provided by Performance Data Helper. I tried to work around with WMI

classes, but it just seems too complicated.

Also, is there any other way to do this?

Thanks and regards
