ZENworks and the Art of Desktop Management
Articles and Tips: article
01 Apr 1998
ZENworks is a product that stands for Zero Effort Networking and reduces the cost of owning networked PCs. This article describes the user and network administrator benefits of ZENworks, summarizes the product's features, offers a typical scenario of how the product can be used, lists system requirements, and answers frequently asked questions.
ZENworks isn't about answering questions like, How do you hold empty space? Or, What is the sound of one hand clapping? It's about providing directory-enabled, cross-platform networking solutions for Windows-based computers. ZENworks takes software management and distribution, desktop management and desktop maintenance to higher levels. It reduces the complexity of workstation management and lowers the total cost of ownership (TCO). And, more importantly, it increases the total value of your networked computers.
ZENworks stands for and delivers Zero Effort Networking for users. By keeping the power of the PC with the user, ZENworks removes barriers to user productivity and allows the experts-network administrators-to leverage Novell Directory Services (NDS) to ensure the user is focused on business, not technology.
The End User and the Desktop Become One
People are mobile, and notebook computers are too. But since the dawn of computer networks, people have been tied to their own PCs because desktops and all of their customization have been confined to specific workstations. Until NDS and ZENworks. NDS maintains and distributes a location-independent "digital persona" for each end user-that is, a unique configuration of desktop policies, profiles, printers and applications, based on who the user is and his or her specific needs. Right down to the wallpaper on the desktop. ZENworks extends the power of NDS so that a user's digital persona can be tapped from any computer anywhere on the network. ZENworks delivers the same unique desktop whether the user logs in from Ohio or Oslo.
The Network Administrator Ponders Existence From a Single Location
While users gain greater mobility and freedom, administrators obtain the ability to stay right where they are. Now software upgrades, repairs and inventories can be accomplished from a single location-there's no need to visit workstations. With ZENworks, network administrators don't need to travel. They can be everywhere in spirit.
Companies See Workstations in a Whole New Light
According to Gartner Group analysts, 78% of network costs are associated with desktop maintenance. According to Forrester Research, the cost of desktop management averages nearly $4,000 per year in the U.S. What's worse, these statistics are probably an understatement. Lost productivity is hard to quantify. In response to what has become a universal problem, information technology companies are generally going down three paths to improve desktop management and reduce costs: intelligent hardware, Network Computers and software. Novell is in favor of whatever works for our customers, and all three solutions have their place.
Leading companies such as Intel and Compaq are developing hardware-based solutions that ZENworks complements. NCs are likely to augment PC investments in organizations for many years to come, and they will need a strong directory presence. NDS and ZENworks provide the directory and the glue that enable NC and PC coexistence. Microsoft is going the software route, and Novell will embrace and extend the manageability improvements Microsoft makes in its operating systems to make them even more manageable. ZENworks bridges the gaps between all three industry approaches-complementing all three.
Application management/software distribution
Applications appear on desktops as needed. The icon simply shows up on the user's desktop and quickly installs itself and configures individual parameters (E-mail address, etc.) automatically.
Applications are self healing so that they work every time, even if necessary files have been deleted from the desktop. Incredible as it may seem, problems simply fix themselves.
Desktop management/custom profiles
Use any computer in the company and retain unique customized desktop configuration, access rights, etc. ("digital persona"). Roaming users always have access to printers that are automatically configured for them. All printer drivers are immediately accessible and install themselves.
Users can use any Windows desktop. Supports Windows 3.1, Windows 95 and Windows NT.
Desktop maintenance/remote troubleshooting
Faster response from the Help Desk.
Remote software diagnosis and repair across the network-no waiting for an IS visit.
Contact the Help Desk and enter a trouble ticket easily.
E-mail all PC and network configuration information to the Help Desk automatically, replacing lengthy phone interrogations.
Network Administrator Benefits
Application management/software distribution
Application and OS upgrades can be implemented automatically from any location.
Network software fixes and patches can be implemented remotely at any and all workstations-greatly reducing downtime, as well as IS staff workload and expenses.
Easily install print drivers and configure printer connections on a workstation. For example, when a user needs access to a new printer, the Help Desk staff simply associates the new printer with the user's object in NDS. After the user logs out and then logs back in, the printer and driver are automatically installed and configured. Again, it's all done remotely.
With the application-management capabilities of ZENworks, any application can become NDS-aware. So, in essence, ZENworks supports all Windows applications, including those of third-party vendors.
Desktop management/custom profiles
Variable substitution capabilities enable information to be pulled from NDS to customize desktop configurations. So, for example, in an automated browser installation, the POP3 server, E-mail addresses and bookmarks can be customized for each user remotely as part of the deployment, without having to visit a single node.
Efficiently implement policies throughout the network without separate utilities. NWAdmin provides the interface; the policy file is stored in NDS and automatically replicated throughout the network. So it is no longer necessary to manually copy policy files to all the servers throughout a network-saving time and providing fault tolerance.
Automatically inventory all PCs on the network, generating reports on processors and amounts of RAM per workstation by querying NDS through the ODBC interface. Through ZENworks, NDS contains a workstation object for every PC on the network.
Desktop maintenance/remote troubleshooting
Centralized control and administration reduces trips to user workstations.
Remote control solution enables Help Desk employees to control machines remotely if they have been authorized through NDS, but prevents unauthorized access to sensitive information.
A single mouse click enables users to verify the existence of all files, registry modifications, and INI modifications. Problems can thus be resolved remotely in minutes.
Supports Windows applications and operating systems- ZENworks supports applications and operating systems (Windows 3.1, Windows 95, Windows NT) from Microsoft; it also supports Windows applications from third-party vendors.
Launches closest application- ZENworks determines the closest application, as configured by the administrator, and launches it. So, let's say you travel to a branch office in a distant city and you need WordPerfect on your notebook PC. All you do is click on the application icon and NDS transparently directs the workstation to download the application from the local server instead of pulling it from across the WAN. Thus bandwidth is preserved and your location-independence is assured.
Supports multi-level folders- Multi-level folders allow administrators to specify where to display applications in ZENworks independent of any tree (directory) organization. As a result, administrators have free reign to organize applications on user desktops. For example, if a company uses multiple word-processing applications, the administrator can create a folder that appears in ZENworks labeled "Word Processing." Two subfolders inside can then contain WordPerfect and MS Word.
Terminates applications- When an application running through ZENworks is no longer valid for a user because of an expired schedule, the application can be terminated according to administrator configuration. The administrator can choose to have the application terminate immediately or warn the user that the application is about to terminate, and give appropriate time to save data and exit gracefully.
Updates NT secure portion of registry- ZENworks incorporates Windows NT system user privileges as well as current NDS user and workstation access to NDS. Distributions through ZENworks are able to modify secure portions of the registry as well as secure files in NTFS. Using ZENworks, an administrator can now successfully distribute applications that require access to the secure portion of the NT registry.
Automates granting of file system rights- File system rights are granted when the application object is associated with the group, user or container. For ZENworks to successfully distribute applications, the logged-in user must have Read and File Scan rights to the file system where the application files reside. This feature automatically grants file rights to users when their container, group or user object is associated with an application object.
Application launch/display priority- Provides a priority number on application objects. Force-run applications are launched in order of priority. Applications that are displayed are sorted according to priority, then alphabetically. For example, in some cases, when administrators want to push an install of multiple applications to clients, the install of the first application will finish and prompt for a reboot while the second application is still installing. This feature addresses this issue by ensuring each installation goes to completion.
Auto-verify- If an application fails to launch due to missing files, ZENworks automatically offers the Verify option to the user to re-copy missing files. This Verify option compares files, registry entries, etc. on the local hard drive to those stored in the application object and only pushes the missing files or registry changes to the local workstation; it doesn't push all the files or registry entries to the workstation.
Copies files by version- When an application is distributed using ZENworks, this feature allows files to be distributed to the workstation conditionally if the file is a newer version as opposed to date or time.
Prompts before distribution- The administrator can flag the application as "Prompt Before Distribution." This prompts the user before any distribution is made, allowing the user to know ahead of time how long it may take and what will be done. The user can then accept or decline the distribution. If the user declines the distribution, the launch is canceled.
High-speed application loading- Application objects load into memory quickly. Specifically, the "Application Files" and "Registry Settings" pages load extremely fast.
High-speed distribution- Applications distribute with surprising speed. Caching reduces the number of calls to NDS and to the file system during the application distribution process.
Supports macros- ZENworks includes macro support for many of the well-known Windows directory locations, including "Startup Folder," "Desktop Folder," "Start Menu Folder," etc. Macros now support many of the well-known login script macros such as file_server, login_name, p_station, etc.
Includes SnAppShot- The application launcher utility that creates easy-to-use templates for building application objects, snAppShot has a new interface with Custom and Express options,as well as many more options to improve its speed and accuracy.
NoseRing Productions on A Roll: A Typical ZENworks Scenario
NoseRing Productions is a real Nineties kind of company, growing faster than anyone in his or her right mind would have dreamed. Employees were stressed out. Up to their eyeballs not only in work, but in technology-related hassles. Until ZENworks came along. Now things are a lot more serene.
Here's just one example why: A NoseRing employee was working on a presentation that was supposed to be delivered in 10 minutes-a presentation that could make or break the company. When he tried to save it, he discovered that the PC was out of disk space and wouldn't allow it. So, aside from panicking, what could he do? Well, since the presentation had to go on no matter what, the user simply started deleting files from a directory named "Navigator," including the navigator.exe. Once that was done, he finished the presentation, saved the company and moved on to the next project.
That next project required researching some facts via the Internet. The user launched Netscape Navigator, and ZENworks sensed that the application wasn't in working order and automatically redistributed the files that would allow the product to run. The user never had to be interrogated about what he did or how the system was changed. It simply worked. Without ZENworks, the user would have probably waited until someone could either visit his desktop or redistribute the application. If not for ZENworks, valuable business time would have been lost. The user would have ended up pondering existence instead of getting his job done.
The following table lists recommended requirements for ZENworks:
Windows 3.1, 95 or NT
