To auto-populate the file, the connector attempts to find domain controllers that are at the same site so there is minimal latency between the connector and Active Directory.

To find the site, the connector determines the subnet on which it resides, based on its IP address and netmask, then uses the Active Directory configuration to identify the site for that subnet. If the subnet of the virtual machine is not in Active Directory, or if you want to override the automatic subnet selection, you can specify a subnet in the file.
