About the Trialversion

The trialversion is a full version of the software that can be used for 30 days. After that it would not start anymore. By getting a licencekey you can reactivate the trialversion to a full functional version of the program without loosing any configuration settings.


What's the software for?

Using NETCOM Desktop Manager is an effektive way providing programs and files within a computer-classroom (Testmanagement!).It gives konsequente controlle over Internet-access with selektiver premission and blocking of single websites, as well as universale controlle of the student-Desktops and xtensive Windows-restrictions. The software enables you to show only those programs on the student-desktop, that are explictitly needed for you lesson.

The very simple and intuitive handling enables the instructor to setup an individualy designed Windows-enviroment all over the classroom.

With these features NETCOM Desktop Manager is an excelent Add-on-Produkt for all video-dedactical-networks.


What can the software do better than other solutions?

The installation of the Netcom Desktop Manager (NDM) is done only at intructors-PC. Student-computers do not need any kind of setup. The Installation is only a filecopy-process - no registry entrys are needed.
Shutting down the student client of the NDM will reset all restrictions und settings. No deinstallation of the programme is affordable.
Because of that the Netcom Desktop Manager is suitable in conjunction with all other softwareproducts and hdd-sheriff-cards.

The use of the NDM does not require any specific knowlege about Windows- or network administration. No administrative action is required: No workstation-administration and at all no administration of user-accounts has to be done by using the Netcom Desktop Manager.
Nevertheless the classroom-map shows all workstations with the workstation-name and the logged on username.
If files and worksheets are handed out and recollected, the NDM knows from witch student the data were collected.

Using computer-classrooms, the teachers normally depend on settings and configurations that were made by their collegues in their role as systemadministrators. The Netcom Desktop Manager enables them for every instructor to configure and setup his individual course environment.
Some instructors may use a more restrictive windows enviroment, while others might prefere a more liberal or open system enviroment. To change from one course-configuration to another, it takes just one mouseclick.

All settings take place immediately "on the fly" - no reboot or relogin of student-PCs is necessary.

Schools and universities often permit the use of their PC-pools outside the lessons and unsupervised standalone PCs are used for surfing the internet. The NDM "StandaloneClient" enables the desktop-control of unsupervised use of these computers. That means that restrictions configured by the Netcom Desktop Manager control the PCs even if no instrucor-module is up.

By the way: Customers from the industry use the NDM StandaloneClient to secure and to configure PC workstations in the productionarea.

Performance-Optimization for student-clients

From MyComuter contextmenu (right mouse button) select "Properties", register "Advanced" und "Perfomance", register "Advanced". Activate the option "Backgroundprocesses".
the performance of the system will not realy be influenced, because of Desktop Manager Client does many little settings one after each other that take very with very little CPU-time. Therefor NETCOM Desktop Manager does not need hugh CPU-time but many times very little CPU-time-slices otherwise the wait-time between the CPU-time-slices will drop performance, while CPU-usage shows less then 2%.


WithInternet-Explorer FTP:// will not be blocked

Deaktivate the option "Enable folderview for FTP-Sides" from Menu ->"Tools"->"Advanced".

Alternativ FTP can be blocked by adding "FTP" to the list of blocked programs of the program-blocker.
