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.
Primary domain controller (PDC) and backup domain controller (BDC) are roles that can be assigned to a server in a network of computers that use the Windows NT operating system. Windows NT uses the idea of a domain to manage access to a set of network resources (applications, printers, and so forth) for a group of users.
