Lab 300 Screen transfer doesn’t work

Direct link

Issue:

Monitoring, Model Student and/or Tutor Screen doesn’t work.

Solution:

Possible causes:

1. Screen Transfer License is not valid or is not installed: You can verify this from the Lab 300 teacher program help menu. You can also try to remove the license and then activate it again. Note, that Screen Transfer license institution must be spelled exactly the same as Lab 300 license has.

2. Screen transfer functions are being blocked by a firewall:
Some firewalls prevent the addition of Media Assistant Duo/Solo and the Crossroad program to the firewall exceptions. Especially in Windows 7 firewall, one usually needs to add the programs manually. Also, some firewalls require that the port for screen transfer is opened separately. In this case, one needs to add port 5060 to the firewall exceptions as well.


Tutor can not send or receive audio

Direct link

Issue:

In the two occurred cases Tutor is run as local admin. If domain user or admin, then it worked OK

Issue: No audio between Tutor and Student
The reason was that the audio ports were reserved by another program (in both cases Video conference application)
Solution:

How to detect:

Activate Tutor discussion with a Student
In CMD run netstat -a -o
Look port 5060 and the corresponding PID number for that port
Open task manager
Select View/Select Columns => Select PID (Process Identifier) to be shown
See what Process corresponds to the PID seen in Netstat

Study Student doesn’t start but gives an error “File access denied”

Direct link

Issue:

Study Student doesn’t start but gives an info “File access denied on <path>. Application is shutting down”

The reason is, that Student Study files directs to a location where the account Student has logged in has no access.
The Study files is set in registry location HKEY_CURRENT_USER\Software\Sanako\Study\Student\Settings
Solution:
Give the needed permissions to student to the desired location or change the location to somewhere student has permissions.

Multicast blocking in Study

Direct link

Issue:

In some network environment it is not possible to send screen to students or Tutor to view students screen.

 

Solution:

SCU32 doesn’t work with new MSU PCI cards

Direct link

Issue

The message format has been changed in the new (=2-port, serial number higher than 100805003) MSU PCI cards so, that they don’t work with older SCU32s anymore. The newer card were released in 8.7.2010, so if the SCU is older than that, it requires a hardware upgrade in order to function.  The new MSU cards work only with SCU322 units with software version starting from 2.2. and FPGA version 101209.

Solution

Install the 2 upgrade chips to the SCU by removing the cover and replacing the chips. The chips are available to order. More precise instructions can be found from the following link:

Student web browser closes after launch

Direct link

Issue

Student web browser closes within 1 sec. after Tutor has launched it

Reason:

Internet Explorer acts in a way that, if a webpage on a certain zone (e.g. Internet Zone) with Protected Mode setting: Enabled, opens a link to another zone, e.g. Local Intranet zone with Protected Mode setting: Disabled, the Internet Explorer can only open the link to new browser instance, with the appropriate target Protected Mode setting. This is a security feature, defined by Microsoft.

 

Study/Lab300 can only function with browsers opened with Study/Lab300 internal command, other browser are automatically closed during the Web Browsing function, and this is what happens when the Protected Mode settings mismatch occurs.

Example:
Most common problem is that the homepage of the school is located in the Trusted Sites lists or Local Intranet, which by default has Protected Mode Disabled. When Study/Lab300 opens Internet Explorer with Study/Lab300 internal command, the browser goes automatically in Internet zone, because it’s not automatically launched to homepage due technical reasons. The Internet zone has the Protected Mode enabled by default. Study/Lab300 commands the browser to navigate to the homepage, which is in the Trusted Sites or Local Intranet zone with Protected Mode Disabled. This causes the Internet Explorer to launch a new window, because of Protected Mode mismatch. However the window was not launched with Study/Lab300 internal command, therefore Study/Lab300 identifies it as a user opened browser, which is not allowed when browsing function is in use, so it will be automatically closed.
Solution

Set the protected mode setting on or off for all three zones (Internet, Local Intranet and Trusted Sites). This setting locates in IE Tools/Internet Options/Security tab.


Lab 300 video window is crashing

Direct link

Issue

When teacher sends video stream from Live Streamer to students, the window and Media Assistant software will crash if trying to touch or resize the video window. Also the streamed video is slow and cutted.

Solution

In some cases the Video setting in the student QT Edit/Preferences/QuickTime Preferences/Advanced needs to be set as “Safe mode (GDI only)” instead of DirectX.

In case there is not internet connection available, the following should be set:

In QT Edit/Preferences/Player Preferences
unselect the “Show Content Guide at Startup”
This avoids the player to hang in loading the content guide from internet.

Study Tutor (in XP) crashed when audio CD selected as program source

Direct link

Issue

In XP, when Tutor selects audio CD or Tutor PC as program source, Tutor application crashes immediately when starting activity.

 

Solution

In Study Sound Setting Wizard there is a device called Loopback device. If there is not selected any device in this point, Tutor crashes. Stereomix (or equal name meaning Stereomix) should be selected, but it stays easily unselected, because user doesn’t always know loopback device means stereomix in this case.

In W7 Loopback device selection is disabled so this instruction doesn’t apply with it.


IE9 starts in http://studentbrowser

Direct link

Issue

When Student has been installed to PC prior to IE9, it might cause the Observer.BrowserMonitor not to install correctly, therefore resulting in http://studentbrowser problem

 

Solution

Uninstall Student, clean out registry branches [HKEY_LOCAL_MACHINE\SOFTWARE\SANAKO] and [HKEY_CURRENT_USER\Software\Sanako], restart PC and re-install Student.

 


Study 6.10 USB headset drivers

Direct link

Study 6.10 USB headset drivers are no need to install manually anymore.

Study 6.10 setup contains USB headset drivers (C-Media). If the headsets are connected when installing, it will ask if you allow to install drivers. If USBs are not connected, then it will not ask anything or install any drivers.

When you afterwards connect USB first time to the computer, it will tell you it installs drivers. However, these drivers are Microsoft default drivers. When you start Soundset, it will ask you if you would like to install proper C-Media drivers.

If you look in sound controllers in Device Manager, you can select USB controller properties and check from there if the drivers are Microsoft or C-Media.


Checking Study component versions

Direct link

Issue:

Study may get strange behaviour if Server, Tutor and Student are not exactly the same version (=same build number). For this reason it is good to check the versions prior other fault finding.

Solution:

In Tutor and Student you can find the build number from Help/About.

In Study Server you can find Server build by selecting StudyServer.exe properties and from there Details tab. StudyServer.exe location by default is C:\Program Files\SANAKO\Shared Components\Server.

The version number format is e.g. 6.10 (6.10.030125.00) where the actual build number is in brackets. In the example 6.10 means version, 030125 means the build date 25 Jan 2013 and .00 is the number of build in that day.

7. reboot the MSU


License activation fails in Study version 6.10

Direct link

Issue

In Study version 6.10 license activation gives an error “Activation failed. Cannot read CMID”. This happens in HP ProLiant Server. The reason for the error is, that this computer motherboard ID number is not available and therefore the CMID can’t be calculated correctly.

Resolution

Run the attached patch in the computer, where you have installed Study server/license server. After running the patch you can activate the license token normally. This issue will be fixed in the next Study version.

MSU file system is inaccessible through Windows Explorer – Lab 100 won’t start

Direct link

Issue

Windows doesn’t see the MSU as shared folder, which causes Lab 100 not to start, usually with smSecComm2 related error message.

Solution

One possibility is that the MSU doesn’t have the Encrypted Passwords set to yes in the smb.conf file. In this case, do the following:

1.     Log into MSU with keyboard+display or via PuTTy from teacher PC.
2.     Use root/stairway as login credentials.
3.     Type: cd /etc/samba/  to enter the Samba folder.
4.     Type: nano smb.conf , a text-editor will come up.
5.     Browse down, and locate the “encrypt passwords = no” line. Change the line as “encrypt passwords = yes”.
6.     Press “Ctrl + O” and Enter to save the configuration file. After saving is done, press “Ctrl + X” to quit the Nano editor.
7.     Write ‘service smb restart’ to restart the Samba service.
8.     Run Lab 100.

Other issue to check:
One has to make sure that the ​the network interface which is associated with the MSU has File and Printer Sharing enabled as well as Client for Microsoft Networks. These settings can be inspected from the adapter settings of the network interface.

It seems this manual is not published otherwere in the new Partner Zone, so I’ll add it here.

The earlier version was 1.0. The only difference here is, that the Lab 100 version and component table has been updated to Lab 100 version 9.0.

Changing to old connection method in Study

Direct link

Issue

In some cases, e.g. when you must install Study Server to a server which is in a different subnet than the Tutor and Students, the current way of connection doesn’t work. The reason is, that broadcasts will not go between different subnets and therefore Tutor and Students will not find Study Server.

Resolution

The “old way” of connection will work without needing broadcasts from the Study Server, so it will work in the above situations.

The connection type can be changed as old way as follows:

TUTOR:
1. Open regedit by typing ‘regedit’ to Windows run
2. Browse to HKEY_LOCAL_MACHINE\Software\SANAKO\Shared Components\CMC\
3. Find key ‘ConnectByName’ and change the value to ‘0’ (‘1’ is the new connection method).
If key ‘ConnectByName’ does not exist, create a new DWORD Value by clicking Edit->New->DWORD Value
4. Rename the DWORD Value to ‘ConnectByName’
5. Browse to HKEY_LOCAL_MACHINE\Software\SANAKO\Study\Tutor\Settings and change key ‘Server’ to the name or IP address of the computer where Sanako Communication Services has been installed to
6. Restart Tutor application

STUDENT:
1. Open regedit by typing ‘regedit’ to windows run
2. Browse to HKEY_LOCAL_MACHINE\Software\SANAKO\Shared Components\CMC\
3. Find key ‘ConnectByName’ and change the value to ‘0’ (‘1’ is the new connection method).
If key ‘ConnectByName’ does not exist, create a new DWORD Value by clicking Edit->New->DWORD Value.
4. Rename the DWORD Value to ‘ConnectByName’
5. Browse to HKEY_LOCAL_MACHINE\Software\SANAKO\Study\Student\Settings and change key ‘Server name’ to the name or IP address of the computer where Sanako Communication Services has been installed to
6. Restart Student application by closing Student.exe from Task Manager. Helper service will start Student again automatically.
