The XSeries desktop virtualization product from NComputing is a platform which allows multiple users to share resources in one host computer using different monitors, keyboards and mice. How this works, is that up to six users each with a monitor, keyboard and mouse can connect to one computer unit through X550 PCI card and XD2 thin client access devices.

The multi network port X550 card for example, sits inside the system unit while the multi device port XD2 is mounted at the back of the monitor. The two hardware components enable connectivity between them, the monitor, mouse and keyboard.

A typical NComputing configuration has an X550 PCI card inserted onto a PCI slot of a system unit with Ethernet cables connected to its network ports at the rear of the computer. The RJ45 terminals on the other end of the same cables are then connected to the Ethernet ports of the XD2 thin client devices. Each thin client (now connected to the X550 PCI card) then connects to a monitor, keyboard and mouse via its VGA cable and PS/2 ports.

One X550 PCI card can support up to five thin clients, and in addition to the host computer, the setup supports one additional monitor.

The final addition to NComputing setup is the vSpace virtualization software which brings the virtual desktop environment to life. When everything is set up and the host computer is powered up, the interconnected monitors will display virtual Windows or other OS desktop.

Requirements for NComputing X550 and Virtualization Kit Installation

In order to set up usable NComputing desktop virtualization platform, your host computer should meet a minimum of requirements:

  • A 3.0 GHz or equivalent Dual or Quad processor
  • 6GB RAM for a 64bit system.

The NComputing kit should have the following components for every XD2 thin client:

  • A PS/2 keyboard and mouse
  • A monitor supporting 800x600 resolution and above
  • Up to 10 and 5 meters category 6 or 5e Ethernet cables respectively

You only need to have one free PCI slot in your host computer in order to install the X550 card.

If needed, two X550 cards can be installed in one host computer in order to accommodate up to eleven monitors. In this case, you should have two empty PCI slots in your computer.

Installation of vSpace Desktop Virtualization Software

Before delving deep into vSpave virtualization software installation, make sure display and other drivers are fully installed. Display drivers will enable optimum resolution in the virtual desktops.

If all is fine head over to the NComputing website and download the latest version of vSpace software, or else, use what came bundled with your hardware.

In our example the vSpace software is installed and configured in a Windows 7 computer.

  • Unzip and run the vSpace Server package or the CD Install version.

  • Click Next to continue
  • In the next two windows you will be prompted to agree to licence agreement
  • Click I Agree and Next in both cases
  • Next you will be prompted to select the initial resolution installation
  • Stick with the Default and click Next
  • NComputing will specify installation folder in Program Files
  • Click Next
  • The installation of video drivers will start

  • Click the checkbox preceding Always trust software from NComputing Inc and Install
  • Upon completion of installation you will be prompted to fill in your data as shown below

  • Restart the computer to complete configuration of vSpace software

Create and Configure Virtual Desktop Users

Now that vSpace virtualization software is installed, you should be able to access the NComputing vSpace folder in Program Files, from where you can register your product and effect additional configuration.

  • In order to configure virtual desktop users, head over to Computer Management tool
  • To do this, type lusrmgr.msc in the Search box, or right click My Computer and tap Manage.
  • Click Local Users and Groups in case of the latter
  • Double click the Users folder in the right pane

  • From the Action menu item, click New User, or right click and click New User in the space inside the User folder in the right pane

  • Create up to five or six users depending (Six users should suffice in a classroom environment)
  • Create passwords for the new users and configure whether these can be changed or not

  • Thereafter, head over to the Groups folder where you will access Remote Desktop Users

  • Remote Desktop users are granted special permission to log into their account remotely
  • Which means the users you created earlier need to be granted this permission
  • To do this,click Add in the next dialog box and enter the users you created earlier

  • Of not here here is that the Add feature will only recognize users already in the Local Users and Groups database
  • After you have entered all the six users, you should see something similar to the image below

NComputing Product Registration

Registration of the NComputing product is the last step before it can be used beyond its limitations.

The initial NComputing configuration will give you only 30 days of use, and sessions limited to only 60 minutes. That is, until the product is registered. Upon registration, these limitations will be lifted.

You can run NComputing registration both online and offline. Make sure your computer is connected to the internet for online registration process.

For offline registration to take place though, you need to have emailed your registration data and XSeries card details to NComputing team will send you a registration licence file which you link to while registering your product in the offline mode.

  • Start by clicking the Start button and All Programs arrow to complete online registration
  • Scroll to NComputing vSpace folder
  • Therein look for and click vSpace registration

  • Click Next to initiate the registration process
  • Click Register vSpace server software
  • The data you entered earlier on will be displayed and you will need to edit the info as required
  • Click Next three times and the activation process will initiate and complete

Troubleshooting Windows Logon Error - 'There are too many users logged in'

A number of issues may crop up even after you have installed and configured the NComputing product correctly.

One issue in particular is related to Windows Logon error. The error reports thus: There are too many users logged in.

This error will happen if you run Windows 7 SP1 or have installed multiple updates in the original copy of Windows 7.

To fix this problem, uninstall these two Windows updates:

  • KB 3003743
  • KB 2984972

Uninstall one of the updates and restart the computer before uninstalling the second one.
