- Verify that all domain controllers are communicating with the central monitoring console or collector.
- View and examine all new alerts on each domain controller, resolving them in a timely fashion.
- Resolve alerts indicating the following services are not running: FRS, Net Logon, KDC, W32Time, ISMSERV. MOM reports these as Active Directory Essential Services.
- Resolve alerts indicating SYSVOL is not shared.
- Resolve alerts indicating that the domain controller is not advertising itself.
- Resolve alerts indicating time synchronization problems.
- Resolve all other alerts in order of severity. If alerts are given error, warning, and information status similar to the event log, resolve alerts marked error first.
- Identify a site that has no global catalog server.
- Review the Time Synchronization Report to detect intermittent problems and resolve time-related alerts.
- Review the Authentication Report to help resolve problems generated by computer accounts with expired passwords.
- Review the Duplicate Service Principal Name Report to list all security principals that have a service principal name conflict.
- Review a report of the top alerts generated by the Active Directory monitoring indicators and resolve those items that occur most frequently.
- Review the report that lists all trust relationships in the forest and check for obsolete, unintended, or broken trusts.
- Verify that all domain controllers are running with the same service pack and hot fix patches.
- Review all Active Directory reports and adjust thresholds as needed. Examine each report and determine which reports, data, and alerts are important for your environment and service level agreement.
- Review the Replication Monitoring Report to verify that replication throughout the forest occurs within acceptable limits
- Review the Active Directory response time reports.
- Review the domain controller disk space reports.
- Review all performance related reports. These reports are called Health Monitoring reports in MOM.
- Review all performance related reports for capacity planning purposes to ensure that you have enough capacity for current and expected growth. These reports are called Health Monitoring reports in MOM.
- Adjust performance counter thresholds or disable rules that are not applicable to your environment or that generate irrelevant alerts.
