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.
One or more servers â known as domain controllers â have control over the domain and the computers on it. Domains are generally made up of computers on the same local network. However, computers joined to a domain can continue communicating with their domain controller over VPN or Internet connection.ser accounts and passwords are managed on the domain controller. When you log into a computer on that domain, the computer authenticates your user account name and password with the domain controller. This means you can log in with the same username and password on any computer joined to the domain.
