A zero value for this measure may indicate that
the Exchange Server 5.5 is not performing any activity on the Exchange
directory or no operations are happening on the Exchange Server 5.5
itself.
A non-zero value indicates that the directory
service has found the required objects in the directory cache thereby
reducing the access.
A high value for this measure ensures better
performance of the Exchange Server 5.5.
