AD_Client_Serverless_Bind.Monitor (UnitMonitor)

Knowledge Base article:

Summary

AD Client Serverless Bind Monitor. This monitor performs a serverless bind and confirms that the domain controller that is returned is in the client’s site or in a site that is defined by the administrator as the “covering” site.

The goal of this test is to verify that a client will be able to find a nearby domain controller for its domain. An informational alert is generated when the responding domain controller is in a different site. A warning alert is generated if no domain controllers are available anywhere for the domain.

Configuration
