The file determines the domain controllers to use for directories that have DNS Service Location lookup enabled. You can edit the file at any time to modify the list of domain controllers for a domain, or to add or delete domain entries. Your changes will not be overridden.

About this task

The file is located in the installDir\IDMConnector\usr\local\horizon\conf directory.

The file is initially created and auto-populated by the connector. You need to update it manually in some cases, such as the following scenarios.

  • If the domain controllers selected by default are not the optimal ones for your configuration, edit the file and specify the domain controllers to use.

  • If you delete a directory, delete the corresponding domain entry from the file.

  • If any domain controllers in the file are not reachable, remove them from the file.
