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.
A domain controller in a computer network is the centrepiece of the Active Directory (AD) services that provides domain-wide services to the users, such as security policy enforcement, user authentication, and access to resources.he limitation is that the domain controller must host a Windows-based operating system. It means that all the domain members must also use the Windows operating system. Fortunately, this limitation can now be overcome by use of Samba.
