What is Eagle Vision?

Eagle Vision is an easy-to-use software solution for teaching and training on networked PCs. Eagle Vision helps instructors manage multiple student PCs in electronic classrooms from their desktop. Using this tool, instructors can remotely control computers with a graphic console; monitor multiple computers simultaneously; share one computer screen with others; restrict students' access to the network connection; and log off, power off or wake up the WOL-enabled computers remotely (WOL: Wake-On-LAN).

Is Eagle Vision another version of VNC?

The Eagle Vision 2 is not an improvement or new version of AT&T Virtual Network Computing (VNC) system, even though it is based on VNC code. In fact, it is client-server application that helps instructors manage multiple computers in electronic classrooms. The important factors which distinguish Eagle Vision from VNC system are as follows:

  • You don't need to launch vncviewer.exe every time you want to connect remote computer. Instead, you can use a console to control multiple computers from your desktop.
  • You can share one computer screen with other computers. It is a perfect solution for computer labs that are not equipped with projector.
  • You can monitor multiple computers simultaneously from your station. You can monitor up to 49 screens at the same time.
  • You can power off / log off / wake up multiple computers. In other words, you can turn on or shut down remote computers before or after class session.
  • You can block the network connection of managed computers (only Release Candidate 2 and above).

For VNC developers, Eagle Vision is not a variation of existing VNC. In fact, it is packaged with the latest version of  "WinVNC.exe" (currently, RealVNC 3.3.x). However, it has a modified version of "vncviewer.exe" (from 3.3.3 R2) to enable "monitoring multiple computers" feature.

/spymode allows users to explicitly set the size of VNC viewer window and the position of VNC connection window. This option also enables /viewonly parameter.

c:\> vncviewer /spymode 2x2:0
c:\> vncviewer /spymode 2x2:1
c:\> vncviewer /spymode 2x2:2
c:\> vncviewer /spymode 2x2:3

You can see 4 tile windows.

When I tried to use eConsole, I am getting a error message "Error occured while retrieving eConsole configuration". What happens?

First, launch eConfiguration application to install eServer and WinVNC services. If you have done this, but still have the same problem, you were probably trying to launch eConsole under Windows XP Limited User account. In Windows XP, the user account does not have a right to modify LOCAL MACHINE registry key. You have two choices:

1) you need to log on as local administrator and give Users group the full access permission on to HKEY_LOCAL_MACHINE\Software\eVision key and its all child objects.


2) you can install a Compatibility AppFix on your Windows XP SP1 or higher. Download Compatibility AppFix.
