Teleconverters, called extenders by Canon, are optical accessories which fit between the camera body and the lens. Theyre essentially tubes with a few glass lens elements inside which multiply the focal length of the lens in use-typically by 1.4x or 2x.
Join Now. We have a remote site with 30 Domain users, we have a Power Edge 2900 with 4 gb Memory running Windows Server 2003 Operating System. We are planning to add a new Domain Controller and keep the existing one as a secondary domain controller. Users are also using the domain controller as a file share server.
If the server performing one of these roles is lost, the domain can still function, and if the server will not be available again, an administrator can designate an alternate DC to assume the role in a process known as seizing the role. Primary domain controller. In Windows NT 4, one DC serves as the primary domain controller (PDC). Others, if they exist, are usually a backup domain controller (BDC). The PDC is typically designated as the first. The User Manager for Domains is a utility for maintaining user/group information. It uses the domain security database on the primary controller.
