Question 3

What does the RID Master do for AD?

Answer 3

Each DC maintains a pool of unique SID’s When that pool runs low, the RID master responds to the request by retrieving RIDs from the domain’s unallocated RID pool and assigns them to the pool of the requesting DC. At any one time, there can be only one domain controller acting as the RID master in the domain.

Question 4

What does the PDC Emulator Master do for AD?

Answer 4

The PDC emulator of a domain is the authoritative source of time for the domain. The PDC emulator should be configured to gather the time from an external source.

Password changes performed by other DCs in the domain are replicated preferentially to the PDC emulator.

Authentication failures that occur at a given DC in a domain because of an incorrect password are forwarded to the PDC emulator before a bad password failure message is reported to the user.

Account lockout is processed on the PDC emulator.

Editing or creation of Group Policy Objects (GPO) is always done from the GPO copy found in the PDC Emulator’s SYSVOL share
