I’ve had a few requests for a way to resolve old alerts on a scheduled basis, as we did with a command line utility in MOM 2005.

This Powershell script retrieves open alerts and makes a date comparison based on the LastModified property of the alert and a user-defined alert age threshold.  It contains the standard connection string, so the script can run as a scheduled task to maintain a rolling set of only X days open alerts.

Get it HERE.
