EDIT 6/25/2009: We have updated the download package to remove the need for dependency on Visual C++ 2008 SP1 Redistributable package. The tool can be found in the same place as before, but the version has now changed to 14.00.0611.003.
Just a quick note to share the news that we have just published the updated Microsoft Exchange Server User Monitor tool, aka. Exmon, for Exchange 2007 SP1.
The updated tool can be downloaded here: http://www.microsoft.com/downloads/details.aspx?displaylang=en&FamilyID=9a49c22e-e0c7-4b7c-acef-729d48af7bc9. If the download page says that the version is 14.00.0611.003 - then you are looking at the correct, new version. If it is something else, go ahead and refresh the page as the updated download might still be replicating though Microsoft Download Center.
The updated documentation can be found here: http://go.microsoft.com/fwlink/?LinkId=142433.
Note: At this time, Exmon can not coexist on the same machine with the Jetstress tool.
