FSMO - if server holding PDC Emulator fail on 2003 / 2008, what happen? Do you want more details? J From PDC emulator master failure The severity of a PDC outage depends on your Service Level Agreement (SLA) and the actual behavior and configuration of the environment. For example, inconsistent password change behavior may affect users beyond what your SLAs allow, or the lack of time synchronization may cause resource access failures. Also, in smaller environments, it may happen that the PDC as the first server in the domain is the only DNS or Global Catalog Server, or is the only domain controller (DC) with a valid SYSVOL in case other DCs did not successfully initiate or maintain SYSVOL replication. The PDC role holder may also be the target for regular file server access. Other than the conditions described above, there is no direct dependency of the domain members on the PDC role holder.

The first domain controller that you deploy in a domain holds the primary domain controller (PDC) emulator operations master (also known as flexible single master operations or FSMO) role for the domain. By default, the domain controller that holds the PDC emulator master role in the forest root domain is the reliable time source at the top of the time-source domain hierarchy for the forest. As soon as you install the first domain controller in the forest, set the PDC emulator in the forest root domain to synchronize from a valid Network Time Protocol (NTP) source or from a hardware clock that is installed on the network. If no time source is configured on the PDC emulator or any other domain controller in the forest root domain, the PDC emulator advertises as a reliable time source and uses its internal clock as the source for forest synchronization.
In this case, no manual configuration is required. You move the PDC emulator role to a different computer. Task requirements. Primary Domain Controller. A Primary Domain Controller (PDC) is a server computer in a Windows domain. A domain is a network of logically grouped computers to which access is controlled by the PDC. Various account types exist in the domain, the most basic is the "guest" or "anonymous login" account. The PDC has an administration account which has overall total control of the domain resources. PDCs[edit] In Windows NT, one DCO serves as the Primary Domain Controller. Others, if they exist, are usually a Backup Domain Controller (BDC).
The primary domain controller (PDC) PDC is typically designated as the "first".[1] The "User Manager for Domains" is an utility for maintaining user/group information. PDC emulation[edit] In modern releases of Windows, domains have been supplemented by the use of Active Directory services. Samba[edit] PDC has been faithfully recreated on the Samba emulation of Microsoft's SMB client/server system. See also[edit] References[edit] Jump up ^ "Domain Controller Roles". Comment faire pour configurer un serveur de temps de référence dans Windows Server. Windows Server includes W32Time, the Time Service tool that is required by the Kerberos authentication protocol.
The Windows Time service makes sure that all computers in an organization that are running the Microsoft Windows 2000 Server operating system or later versions use a common time. To guarantee appropriate common time usage, the Windows Time service uses a hierarchical relationship that controls authority, and the Windows Time service does not allow for loops. By default, Windows-based computers use the following hierarchy: Configuring the Windows Time service to use an internal hardware clock To have us configure the Windows Time service to use an internal hardware clock for you, go to the "Here's an easy fix" section.
