Is the Active Roles Administration Service aware of Active Directory Sites? -
説明
When configuring an Active Directory Connector in the Active Roles Synchronization Service, there are only two options: to connect to any Active Directory Domain Controller in the domain or to connect to a specific Active Directory Domain Controller.
When using the option to connect to any Active Directory Domain Controller in the domain, is the Active Roles Synchronization Service aware of Active Directory Sites and will the service attempt to connect to an Active Directory Domain Controller that is in the same site as a preference, or will the connect to any Active Directory Domain Controller in the entire domain? -
原因
When connecting using an Active Directory Connector, the Active Roles Synchronization Service utilizes Microsoft DLL's. Because of this, the Active Directory Connector leverages Microsoft implementations of Locator and DNS. -
対策
If the Active Roles Synchronization Service has an Active Directory Connection defined for a separate forest contoso.lan, the Sync Service initially submits the following DNS query for an SRV record in:
_ldap._tcp.ADSite01._sites.gc._msdcs.contoso.lan
If there happens to be an Active Directory Site in DNS with that same name in contoso.lan, then the Sync Service will use the first Active Directory Domain Controller in the response. If this query fails, then a more general DNS query is issued:
_ldap._tcp.gc._msdcs.contoso.lan.
