in this week i’ve been attending a lots of sessions on the Microsoft Server Summit Reloaded 2010 in Stuttgart. Lots of Information about the new products like Sharepoint 2010, Forefront 2010, RMS 2010, App-V, Med-V and VDI.

So stay tuned about lots of new information about this event.

On Wednesday we had an event in one of the finest event locations in Suttgart. Great event!

Maybe some of you have already noticed it. If you do a message tracking on an Exchange 2010 Edge server you get an error message like this:

Error message: The process “ExTRA (PID=4888) has been initialized as unknown multiple instance type unexpectedly.
Reasons of this exception:

1. For any product executeables,which will be shipped out of box, they should never use AD driver functionality without initializing its performance counter instance since we can NOT show a intuitive Perf Counter instance name here.
2. We don’t need the validation for test assembly because we don’t care for its performance counter missing; however,we definitely want to make sure it is under our control, so that we don’t miss any out of bos product DLLs/EXEs.

What to do avoid this exception: For any newly added exchange test executables which utilize AD perf,please add the executable name of the process into exclusion list in Microsoft.Exchange.Data.directory.globals.checkexchangetestexecutables.

To work around this issue for the moment, use the Get-MessageTrackingLog cmdlet to track the messages in Exchange Management Shell on the Exchange Server 2010 edge server.

The hotfix for this issue is scheduled to be included in Exchange Server 2010 Service Pack 1 (SP1).
