I'm trying to create a monitor set to monitor for active logins on the Info store to alert if the info store unmounts. I'm getting the following error. Does anyone know how to fix this:

The service was unable to add the counter '\MSExchangeIS Mailbox\Active Client Logons' to the KCTR$2246 log or alert. This log or alert will continue, but data for that counter will not be collected. The error returned is: Unable to parse the counter path. Check the format and syntax of the
specified path.


The service was unable to add any counters to the KCTR$2246 log or alert. This log or alert will not be started.
