LanSchool Frequently Asked Questions

Yes! However, trial version students will not be discovered until you’ve copied the student installation file to the appropriate location on the teacher. See the installation guide for further instructions on how to use the “Update LanSchool on Selected Students” feature.

The latest version of LanSchool is 7.6.1.9

The system requirements are available here

Our install guide and user’s guide are a great place to start. You can find the documentation here or within the Customer Portal where you download the product install package. You should also check out the tutorials which explain how to use the various product features.

There are potentially a number of reasons why this can happen. To correct his problem, please ensure that these requirements are followed:

• Verify that there are no personal firewalls blocking the LanSchool port. LanSchool configures the firewalls that are included with the OS to allow the necessary traffic, but there are a large number of third party firewalls which we do not automatically configure.
• Check to see if you have two or more Network Interface Cards (NICS) available, and if so, is the correct NIC being used. The easiest way to verify this is to go into the Preferences menu in the product console, select the Network tab and choose the appropriate NIC for LanSchool to use.
• Verify that the Teacher and Student computers are on the same subnet. If they are on different subnets then Multicast or IP Directed Broadcast must be enabled in the Network tab of the Preferences dialog.
• If you are using a Cisco wireless access point, turn off the port-protection policy setting that blocks peer-to-peer traffic.

By default, Teacher machines are assigned a single channel during installation. The System Administrator must explicitly grant individual Teacher machines the right to view more than one channel by running the EnableChannelSelect tool on the local Teacher machine after it has been installed. Otherwise this option will be grayed out in the Teacher Channel section of the Network tab in the Preferences dialog in the console.

All LanSchool normal traffic is on port 796 (0×031C) (either source or destination). LanSchool “status” traffic is sent to port 1053 (0×41D).

By default, LanSchool assumes that all Students will be on the same IP-subnet as the Teacher. However, it is possible to configure it to function properly even when the Teacher resides on a different subnet (or even a separate segment) from the Student. Please review the Network Configuration section of the LanSchool installation guide for more information on how to do this.

One of LanSchool’s strengths is its efficient screen capture and transfer methods. For instance, if the entire teacher’s screen is changing, LanSchool only uses about 24Kb/sec to transfer that image to the student’s screen. This is less than 1% of a 100 MB network. Because we use a broadcast packet, the bandwidth consumed is the same with 2 computers as with 200 computers. The bandwidth used by many competitive solutions will actually increase with every computer on the network.

For all products except the Report Server (which is a component of Tech Console), LanSchool uses the original installation file to uninstall the product. It behaves like a toggle switch. For example, on Windows, executing the .msi file once installs the product. Executing the same file a second time uninstalls the product. If you ran it again, it would then re-install the product.

This uninstall process requires that the install package be exactly the same file and version as the original file. The install package (.msi, .dmg, etc.) is found in the platform sub-folder (Windows, Mac, etc.) of the product download location. If the product download location is no longer accessible, please contact Technical Support for assistance.

The Report Server uninstall is available from the Windows Control Panel.

LanSchool does support NComputing devices. However that support is dependent on the model number, operating system, and version of the vSpace software supplied by NComputing. Please refer to the table below for the currently supported platform combinations with LanSchool v7.6 software.

LanSchool prevents students from using cached copies of the Student msi file to uninstall. Unfortunately it makes uninstalling LanSchool just a bit harder. To uninstall silently, run ‘msiexec.exe /i Student.msi /qn REINSTALLMODE=vomus’.

No, both of these operating systems shipped after LanSchool v6.5. We recommend upgrading to the latest version of LanSchool.

LanSchool is not a virus and is not infected by a virus. It is a false-positive that is occasionally triggered in some Anti-virus products when a new version of the software is released. Please update to your provider’s latest pattern file and scan the machine again. If the behavior continues, please notify support@lanschool.com and we will send a message to your anti-virus vendor asking them to fix the problem.

Under CONTROLLER on the WLC configuration page change “Ethernet Multicast Mode” from “disabled” to “unicast”.
Also enable the broadcast forwarding option. On some older Cisco access points you must disable the port protection policy that blocks peer-to-peer traffic.
