Use this Knowledge Script to monitor the connectivity between a domain controller and selected domains included in the scope of the target: domains included in the run target or selected on the Objects tab. This script raises an event if the connection to any trusted domain fails.
Trust relationships are fragile, and problems with them are hard to diagnose. Broken trusts prevent users from logging in or accessing cross-domain resources.
The most common reason for broken trust relationships are:
No domain controllers are available for a remote domain.
Trust password is not synchronized properly.
Active Directory trusted domain
The default interval for this script is Every 30 minutes.
