Guest Pintu Posted December 3, 2007 Posted December 3, 2007 Hi, I there such thing as Primary Domain Controller and a Secondary Domain Controller in Windows 2003 Domain? Can you have 2 domain controller in Windows 2003 Domain? I think the answer is Yes. If you 2 Domina controller - what roles do these have. Doesn't one server have to have something that the other server does not have - like Global Catalog? Thanks, P
Guest mymanchris@gmail.com Posted December 3, 2007 Posted December 3, 2007 Re: Is there such thing as Primary DC and Secondary DC ? Each domain must have 1 (and only 1) Primary Domain Controller, or PDC. It can have as many Backup Domain Controllers, or BDCs, as you wish (I'm not sure if there's any physical limitation on this or not). The PDC stays synchronized with the BDCs and in case of failure of the PDC, one of the BDCs gets "promoted" to PDC and assumes that role. When the PDC comes back, it becomes a BDC until it is "promoted" back into PDC role. Perhaps one of the MCSEs in the audience can provide more detail on the inner workings of election processes, but that's the 10,000 foot view of domain controller roles. Hope that helps.

In W2k and W2k3 domains all Domain Controllers are equal. There are no backup DC's. However, there are roles (Operations Master Roles) that are assigned to one (and only one) DC: Schema Master Domain Naming Master PDC Emulator RID Master Infrastructure Master The first two are one per forest, the other 3 one per domain. In addition, a DC may or may not be designated a Global Catalog (there must be at least one). As far as users are concerned, all DC's are equal. They can be authenticated by any DC. The ones with the roles just have extra responsibilities. -- Richard Mueller Microsoft MVP Scripting and ADSI Hilltop Lab - http://www.rlmueller.net -- <mymanchris@gmail.com> wrote in message news:2c1d139b-e028-4bc0-b576-1ae75d084838@a39g2000pre.googlegroups.com... > Each domain must have 1 (and only 1) Primary Domain Controller, or > PDC.
