When a computer joins the domain, it does not know which site it belongs to.
It queries for _LDAP._TCP.DS._MSDCS.domainname.com
Every DC registers this record, and the DNS server will reply with a
randomized list of all the DCs in the domain.
The client then picks the first one in the list to connect to and join the
domain.
This DC could conceivably be on the other side of the planet.
The only way to control this behavior is to use the priority and weight
fields on the LDAP records.
You would increase the priority and weight for the DC you want computers to
use when joining the domain.
Then when the client qeries the LDAP record, the DNS server will order the
reply based on priority and weight.
The record with the highest priority will then be used when joining the
domain.
