ZENworks for Desktops 4 includes new components that allow for Web-based delivery of ZENworks services through a Web browser. This section discusses the components that allow the ZENworks workstation management tools to work without an installation of the Novell client on the workstation. ZENworks for Desktops Management AgentThe ZENworks for Desktops Management agent is a small set of workstation applications that enable the workstation to be managed from a ZENworks for Desktops server. You can install the Management agent on a workstation that does not have the Novell client or on workstations that do have the Novell client. The agent provides full functionality regardless of whether the client is present. If the client is present, however, the Management agent may use some client features to provide additional access points (for example, no Middle Tier server specified). Additionally, if the client is present and for some reason cannot make connections to the services needed, the ZENworks for Desktop Management agent will automatically divert its requests through any specified Middle Tier Web server. You can install the following Management agent components on a workstation:
Corporate FirewallCorporate firewalls are simply combinations of hardware and software that restrict access to the internal corporate network from the rest of the Internet. This feat is accomplished by restricting access to certain addresses and ports. ZENworks for Desktops Middle Tier ServerThe ZENworks for Desktops Middle Tier server is a NetWare or Windows 2000 server that has ZENworks agents installed in the SYS:\XTIER\ directory on NetWare servers and <Windows Source Drive>:\oneNet directory on Windows 2000 servers. These agents provide the NCP communication necessary to provide clientless authentication to the network as well as facilitate ZENworks for Desktop workstation management traffic to and from a clientless workstation. Clientless workstations attach through the DNS name or IP address of the Middle Tier server. NOTE If you are running ZENworks for Desktops in a Windows only environment, the ZENworks for Desktops Middle Tier server must be a member of the same domain as your ZENworks for Desktops servers. The Middle Tier server can be the same server as your ZENworks for Desktops server. Web ServerThe ZENworks for Desktops Middle Tier server must have one of the following Web server engines running on it to provide the HTTP communication between the workstations' browser and the Middle Tier agents:
ZENworks for Desktops ServerThe ZENworks for Desktops server provides the final piece of the clientless workstation management model by providing NCP access between the administrator using the ZENworks for Desktops management tools and the Middle Tier server that is providing the HTTP communication to the clientless workstation. The ZENworks for Desktops server can treat the clientless workstation as any normal managed workstation and can distribute files to it, gather inventory data, and provide remote control sessions. |
