Hello,
   When running the query "SELECT * FROM 
Win32_PerfRawData_EXOLEDB_MSExchangeWebMail" via WbemTest against a Windows 
2008 Server 64-bit machine runnning Exchange 2007 64-bit with the namespace 
specified as '\\machineName\root\cimv2' I received data back.  When running 
the exact same query using CIM Studio against the same machine, namespace, 
etc., I receive the error "Invalid Class".

A query such as "SELECT * FROM Win32_PerfRawData_PerfOS_Processor" works via 
both WbemTest and CIM Studio when directed agains the same machine, so it 
appears there's something different about the  
Win32_PerfRawData_EXOLEDB_MSExchangeWebMail class.


If I run the exact same problematic query (i.e. "SELECT * FROM 
Win32_PerfRawData_EXOLEDB_MSExchangeWebMail") against a Windows Server 2003 
32-bit machine running Exchange 2003 32-bit, both tools return the same 
expected results.

Both WbemTest and CIM Studio are launched via the Start menu on the same 
machine in the same session, and no credentials are explicitly specified 
(i.e. both inherit the token from Explorer), so there should be no credential 
difference.

Why the difference between the two tools?

Thanks,

Matt

Hi,

Out of interest, where did you obtain CIM Studio? At one point it was 
very out-of-date, but maybe you found a new version?

That's the version I downloaded and ran.  To give you more information, the 
machine on which I am running both WbemTest and CIM Studio is a Windows 2008 
64-bit machine.  I copied over a WbemTest.exe from a Windows 2003 32-bit 
machine and ran it on the Win2008 x64 machine.  It reported the same invalid 
class error.  So, 32-bit WbemTest returns "Invalid Class", while a 64-bit 
WbemTest returns the expected data.  Putting this information together with 
the information in my original post, it would be reasonable to conclude that 
certain performance counters are only available to 64-bit processes, which of 
course makes no sense.  So, three questions remain if that hypothesis is 
correct:

1)  Which counters are affected by this?
2)  Is this documented behavior, i.e. I am aware of nothing that states that 
certain performance counters can only be obtained if the client process is a 
64-bit application?
3)  What's the workaround?

It says "data published" 7/19/2002

Year 2002, is that for real??

Hi,

Unless it's a brand new version of CIM studio, I don't see how it can 
work on Win2008 x64?

Hello Jonathan, I'm still waiting for a reply on this.  It's been a week

Hi Matt,

Let me follow-up with the WMI Team and see what I can find.

Thanks,

Here is what I got back.  Since you are on a 64 bit machine the provider of 
the class is only 64 bit.  When using a 32 bit client, like CIM Studio or 
the 32 bit wbemtest, it is unable to find the schema from the 64 bit 
provider, in particular the class.  Cim Studio and its related WMI Tools 
were developed a while back and were not intended for use against a 64 bit 
machine.

Hi Jonathan, that answer makes no sense.  

Here is a summary of the results I've gathered for the query "SELECT * FROM 
Win32_PerfRawData_EXOLEDB_MSExchangeWebMail":


Win2K3-R2 Ent SP2 32-bit to Win2K8 Ent SP1 64-bit Exchange 2007
     32-bit client succeeds
     64-bit client N/A


Win2K3 R2 Ent SP2 32-bit to Win2K3 Ent SP2 64-bit Exchange 2007
     32-bit client succeeds
     64-bit client N/A


Win2K3 R2 Ent SP2 64-bit to Win2K8 SP1 64-bit Exchange 2007
     32-bit client fails with 'Invalid Class' error
     64-bit client succeeds


Win2K8 Ent SP1 64-bit to Win2K8 64-bit Exchange 2007
     32-bit client fails with 'Invalid Class' error
     64-bit client succeeds


Win2K8 Ent SP1 32-bit to Win2K8 64-bit Exchange 2007
     32-bit client succeeds
     64-bit client N/A

Also, on a Windows 2008 64-bit Machine, I installed a 32-bit version of 
WbemTest, and it returned 'Invalid Class' when invoked against a remote 
64-bit machine, while running the same 32-bit version of WbemTest invoked 
against a remoted 64-bit machine from a 32-bit OS worked fine.  All other 
queries using a wide variety of raw counters succeed for both 32-bit and 
64-bit clients.  So, the same questions still remain:

Which classes are affected by this and why?
What is the workaround?

The person who you forwarded this to apparently lacks the expertise 
necessary to get a definitive answer.  I'd appreciate it if you found 
somebody else with the requisite knowledge.

Thanks,

Matt
