1.4 Relationship to Other Protocols
The Remote Procedure Call Location Services Extensions depend on the following protocols:
Locators depend on the domain controller (DC) and domain discovery mechanism [MS-ADTS] to obtain information about domains and to select their mode of operation, as specified in section 3.1.3.1.
Client locators depend on Remote Procedure Call Protocol Extensions [MS-RPCE] for forwarding requests to the master locator, as specified in section 3.3.1.4.
Master locators depend on the Remote Mailslot Protocol [MS-MAIL] to broadcast requests for the queries they receive, as specified in section 3.4.1.5.1. Server locators depend on the Remote Mailslot Protocol for responding to broadcast requests, as specified in section 3.2.1.5.
Client locators depend on the Remote Mailslot Protocol to dynamically discover the master locator, as specified in sections 3.3.1.4.3 and 3.4.1.5.2.
Server locators depend on Lightweight Directory Access Protocol (LDAP) [MS-ADTS] for persistently storing name service entries in the Active Directory store, as specified in section 3.2.2.4.
Client locators depend on LDAP [MS-ADTS] to look up persistently stored entries in Active Directory for the name service entries, as specified in section 3.3.2.4.
No other protocols have a dependency on this protocol.
The following diagram illustrates the layering of the protocols.
