Peter,
which formulas are you interested? Most of the rules fire based on flat thresholds, which match the thresholds published in the Troubleshooting Exchange Performance whitepaper. Is there an area of particular interest where you would like more detail?

Chiel Varkevisser,
If your problem is not due to problems with the locale of the machine ExPTA is run on, please send a result file (with the error) to
nicolebo @ microsoft . com

The result file is an xml file located in the %APPDATA%\microsoft\expta folder (the appdata folder is usually C:\Documents and Settings\<username>\Application Data).

In response to the errors "Error accessing RPC performance counters. String was not recognised as a valid DateTime.." - this occurs when the system locale is not set to US english.
This is a bug that will be fixed in the August release, but won't occur if you are running en-us.

Same problem here, Windows XP SP2 collecting data from a Windows 2003 SP1 Exchange 2003 SP2 server, and it's ""error accessing 'MSexchangeIS' RPC performance counters. "String was not recognized as a valid Date time"

I'm also getting the same errors that Ed and Chiel are getting. Has anyone found a fix for this?

I was talking to Chiel Varkevisser today the problem he has is
"failed toretrieve performance counter data from file......"
and next this error is displayed.
""error accessing 'MSexchangeIS' RPC performance counters. "String was not recognized as a valid Date time".

(ehm.. can we confirm on a date time format to use ???
(or could MS think of an algorythm to retrieve correct date/time

Even when I run ExPTA from WinXP SP2 or Win2003 I get the same 2 error messages as Ed mentioned: "Failed to retrieve performance counter data" and "Error accessing RPC performance counter data".

The improved version of Nicole does not solve this issue.

What would be proffesional is also providing the caclulation
formula's used by these tools. So someone can monitor
those same valeus in perfmon export to excel
do some calculation and present these in a an excel graph.

Why because when your 'sometimes' in problems you would like
to take long measurements for specific problems.
While all counters have some good reskit explainations.
I would like a Q art about the formula's used by these tools.

Performance data collection and analysis will not work when ExPTA is run on Windows Server 2000 and Windows XP Sp1 machines

ExPTA must be run on Windows XP SP2 or Windows Server 2003 machines. Note ExPTA can collect and analyze data from Windows Server 2000 machines, as long as ExPTA is running on a Windows XP SP2 or Windows Server 2003 machine. However, only the first option (to collect and analyze data) will work against a Windows Server 2000 server, and it is the only option that will appear.

The error messages that display when reading a data file or collecting data on Windows Server 2000 and Windows XP SP1 machines were misleading. An updated configuration file that contains improved error messages is available at microsoft.com (http://www.microsoft.com/downloads/details.aspx?familyid=4BDC1D6B-DE34-4F1C-AEBA-FED1256CAF9A&displaylang=en)

I apologize for the problems this has caused, and hope this information is helpful.

Responding to DaveB's question above: ExPTA must have network connectivity to the Exchange server and a domain server in order to process the data, as ExPTA gathers other information from the system (such as the location of data files, and the number of processors) to measure the server health.
