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.
