Net Control 2 Standard Edition v11.10 compatibility note.

Among other changes and improvements in Net Control 2 Standard Edition version 11.10, this version uses a modified protocol for direct connections that provides additional security measures for Net Control 2 clients that do not use authentication or connection filtering features.

Unfortunately these changes make impossible using version 11.10 of Net Control 2 Client (Student) module with older teacher modules.

If the teacher module has version below than 11.10 and it attempts to connect the student module of version 11.10 or higher with direct connection model, such connection will be displayed with “waiting for screenshot” logo and no commands may be applied to the student computer.

Solution: update the teacher module to the latest version over existing installation, removal of the previous version is not required.

Net Control 2 version 11.02

This update includes several improvements for Net Control 2 Broadcast Desktop and Remote Desktop engines.

Now it is possible to enable the “lossless compression algorithms” mode, when an image will be compressed and sent to viewers with exactly the same color depth and quality as it was captured on the sender’s party. This makes possible to avoid lossy compression artefacts: color fading and a color “noise” around text and high-contrast elements. On another hand, lossless compression requires a wider network bandwidth and low latency networks, therefore it is disabled by default.

To enable the lossless compression, you need to modify settings on the sender’s party: i.e. on the teacher computer for Broadcast Desktop tool, and on student computers for Remote Desktop tool. To enable the option on a teacher computer, in the teacher console click the main menu command N – Options – Options. On Control/Broadcast page enable “Lossless (bet. quality lower performance” option and click OK. To enable this option on student computers: select student computers in the teacher console, then click the main menu command N – Options – Client Options. On Control/Broadcast page enable “Lossless compression” option and click OK.

Net Control 2 Version 11.02 also includes several improvements for the automatic broadcast protocol mode introduced in version 11.01 in the part of the performance and stability.

Net Control 2 version 11.01

Net Control 2 version 11.01 is available for download on our website

This minor update includes several improvements for Broadcast Desktop and Remote Wake-up features, as also for the remote update procedure in Net Control 2 Professional Edition over Connection Server Management Console.


Broadcast Desktop now uses an improved internal protocol of data transmission, which should recognize supported by the network infrastructure network protocols, and adjust broadcast settings automatically. So for the most situations no additional configuration for Broadcast Desktop tool will be required.

Please note, this new protocol is not compatible with old versions of Broadcast Desktop clients. Therefore, to use Broadcast Desktop features all your computers and devices must be updated to version 11.01.

Wake-up command uses settings of Broadcast Desktop tool for forwarding the signal to other subnetworks. In many cases this makes possible to wake up computers that are located in other subnetworks/VLANs, if broadcast addresses of these subnetworks are entered in Broadcast Desktop settings.

Thumbnails in the connection list of the teacher module now have special boxes/buttons for easy selection of multiple connections on keyboardless devices like tablets.

For PRO Edition: the teacher module updates downloaded from Connection Server are installed automatically without elevated privileges prompt. Earlier, when an update was downloaded to a teacher computer, the teacher console has displayed a prompt to update the software, the teacher could accept or forbid the update procedure. If the update was allowed, the teacher  was required to have administrative privileges or to enter administrator credentials in order to continue the update. Now the administrative privileges or credentials are not required, the update will be done automatically.

Net Control 2 — 11.0 build 5882

This minor update fixes repeating “Access violation at 00621Axx” message that may appear in the teacher console (version 11.0) in several conditions when an inverse connection was unexpectedly terminated.

To fix the issue:

  • close Net Control 2 teacher console;
  • install Net Control 2 11.0 build 5882 package over existing installation.

Removal of a previous version or restart is not required. The teacher module should be updated only.

For any additional information regarding the issue please contact Net Control 2 Support team.

Net Control 2 version 11 build 5858

This minor update adds support of Edge browser for Net Control 2 Internet Control engine in Protocol Layer mode.

Edge (aka Project Spartan) is a new browser from Microsoft, which becomes a part of the operating system in Windows 10 and replaces Internet Explorer.

In order to use Net Control 2 web restrictions in Edge browser (as also in Chrome. Firefox, Safari and Opera)  Net Control 2 Internet Control Engine should be installed in Protocol Layer mode. This mode is used by default for all new installations.

Previous versions of Net Control 2 may use Internet Explorer Plug-in mode, so Internet restrictions work in Internet Explorer only and other browsers are automatically disabled when the restrictions are in effect. If Net Control 2 was updated to version 11 from some previous version and Internet restrictions work in Internet Explorer only and do not work in other browsers, you may need to re-install Net Control 2 Internet Control Engine as follows:

  • select student computers in the teacher console;
  • click the main menu command N – Options – Client Options;
  • on Internet tab of the appeared Client Configuration window, enable “Mode 2: Install as Protocol Layer + IE addon (recommended” option;
  • click OK. Changes will be applied after restart of student computers.


Net Control 2 version 11 is here!

Net Control 2 PRO - Registered

We are proud to release today the next major update for our award-winning classroom management software solution Net Control 2, in Standard, PRO and SmallClass editions.

With this release we are opening a new page in development of this project. Most of the program code was moved to a cross-platform framework, which makes possible building software modules for platforms other than Microsoft Windows. In the near future we are planning to present a special version of the teacher module for Macs, and some time later for iOS and Android.

New version of the teacher module for Windows uses capabilities of DirectX technology to make the presentation features more attractive and effective for teaching and learning.

Several new tools were added in version 11 and many existing tools were revised and improved.

New Quiz Constructor allows creating complex quizzes that include several sets of questions for different groups of users in one quiz. Questions may be differentiated by a complexity level or a variant number. So, the teacher can send one quiz to all students, but each group of students will work with its own set of questions, depending on the assigned to the group variant, or the complexity level.

New version of Quiz Constructor simplifies the way of questions creation: all questions may be edited in one table view, all at once, instead of designing each question individually as it was in previous versions. With the current model you can prepare your quiz 2-3 times faster. In addition, now you can also import questions and answers from an (Excel) CSV or text file, or export them to CSV and HTML file formats.

Net Control 2 version 11 includes a new completely redesigned whiteboard tool. Drawn lines and shapes now are represented as objects, and may be easily moved, scaled, rotated or transformed. Now you can easily insert text, graphic files and objects from other programs, capture screen and use it as the board background. We have optimized whiteboard tool for transparent synchronization with new users: even if some students join a whiteboard session after it has begun, they still will see the same picture as other students that were connected to the teacher initially.

Actions performed in Whiteboard session may be stored in special files, and used for further replay on teacher or student computers.

In version 11 we are happy to introduce also new Grades tool. Now teachers can grade students for complete quizzes, correct and incorrect poll results, or for any other event. Grades with optional comments may be shown on student computers, stored, exported or printed.

With the new Planner tool teachers can create and manage lesson plans as a timed set of events or tasks. In the process of the lesson the planner will display in the teacher console, according to the schedule, comments for the teacher, run macros and commands, open tools, helping the teacher to concentrate attention on the lesson details.

Internet restrictions will work now in all major browsers by default. The list of supported browsers includes Internet Explorer, Google Chrome, Firefox, Safari and Opera. Custom browsers may be added by request.

In version 11 we added a new way of sending files from student computers to teachers. Now Net Control 2 maintains a special exchange folder (by default it is placed in Net Control 2 Common Files\AutoCollect folder on user’s Desktop). Any file copied, saved or changed in this folder will be automatically synchronized with connected teacher computers, and display a notification on them.

Administrators that use Net Control 2 Professional Edition in Windows domain environment with Active Directory services enabled will notice a far better integration of Connection Server authentication services with Active Directory database. Teachers now may be authenticated on Connection Server with their Windows logins or by their membership in a user group. For example, enabling access in Connection Server Management Console to the server for some Windows user group “teachers” or “administrators” will make it possible that all domain user accounts that belong to this user group will be automatically authenticated.

Net Control 2 version 11 includes many other minor improvements, not covered by this document. The more detailed description of major changes is provided in the following article:
