PolicyServer and related databases are mission-critical services. Trend Micro recommends the following for optimal maintenance of your Endpoint Encryption product and related services:
Actively monitor CPU usage and establish a threshold for when the PolicyServer Windows Service and Trend Micro Endpoint Encryption Service should be restarted.
Restart the service on a regular schedule that fits with the organization's established maintenance windows (daily, weekly, monthly).
Restart the PolicyServer Windows service whenever maintenance is performed on the Active Directory environment, the server, database, or related communications.
Back up PolicyServer databases when you back up similar enterprise-critical databases.
Back up primary and log databases regularly off site for redundancy.
Any changes to the Active Directory or database environments may affect connectivity with PolicyServer.
