Configure domain controller polling in dc_config.txt

By default, DC Agent automatically identifies domains and domain controllers at startup, then detects when domains or domain controllers are added or removed from the network. This process is called domain discovery (see Configure DC Agent settings).

DC Agent stores domain and domain controller information in a file called dc_config.txt (located, by default, in the C:\Program Files\Websense\Web Security\ bin\ directory on each DC Agent machine).

• You can edit the dc_config.txt file to change which domain controllers a DC Agent instance polls. Do this, for example, to:
  • Enable load balancing across multiple DC Agent instances.
  • Stop DC Agent from polling domain controllers that don’t exist.
• If you do not want DC Agent or User Service to perform domain discovery, you can create and maintain the dc_config.txt file manually.
• You can review domain and domain controller information from dc_config.txt in the Security Manager. Go to the Web > Settings > General > User Identification page and click View Domain List.

  Note that the DC Agent Domains and Controllers page lists information for the DC Agent instances associated with a specific Policy Server. You may need to use the Policy Server Switch button in the Web toolbar to select the Policy Server associated with the DC Agent instances you want to review.
