There are two ways of updating the client OS. One is using a USB memory (locally) and the other is using a network interface (remotely).

1) Using a USB memory
Step 1.  Make a USB disk memory, bootable (you may use the USB disk format tool by SAMSUNG USB format tool). Copy the client OS image (downloadable from this site) and recovery utilities such as Symantec Ghost or SFIM to this USB memory.

Step 2.  Connect the USB memory to a client (LFD) and boot it using the USB.  You would have to configure the client to boot from USB from the Advance BIOS settings.

Step 3.  Using image recovery utilities, replace the client OS image with that in the USB memory.

With SFIM you could use:
sfim  /r:1  os_image_name.sfi

where sfim is the recovery utility /r:1 is the recovery switch and 1 means you are updating from USB. Finally, os_image_name.sfi , is the new OS that you are going to install.

2) Using a network interface
Step 1. In order to use a PXE (Preboot EXecution Environment ) to make a network boot server, put image recovery utilities and client OS images in a file server and configure a system.

Step 2. Make sure that the boot order has been set to start from the PXE. Then, restart the system in PXE mode.

Step 3. Using the image recovery utilities and client OS images in the file server, update the client OS. In order to use SFIM, use would require placing the SFIM executable in the file server along with the client OS.

This phenomenon occurs when the OS of your client has been damaged. You should recover the OS using a USB memory or a network interface

How to prevent:

If you make the Enhanced Write Filter (EWF) state Enabled, all data that can affect the OS is not stored, so that no data you created and used while working at the computer is applied to the client after you restart the client. If you make the EWF state Enable, a problem like this would not occur again.

Please note that once you enable EWF, any new program installation or change in (C:\), for instance, network or desktop settings, would only be saved if you commit the changes to the OS. One of the ways is to type: ewfmgr c: -commit, in the Command Window, and press Enter.

1. Access the conf folder – a sub folder of a folder which MagicInfo-i has been installed – and open the config.properties file with Notepad.
2. Replace the Server IP with the new one:
###################################################################
# Web Service Remote Management Configuration
###################################################################
# WS-Addressing Header [From]
ws_addressing.header.from =
http://[Changed Server IP]:[Server Port]/MagicInfo/WSRMReverse
# WS-Addressing Header [ReplyTo]
ws_addressing.header.replyTo =
http:// [Changed Server IP]:[Server Port]/MagicInfo/WSRMReverse
......
# Event Subscribe
server.address = http:// [Changed Server IP]:[Server Port]/MagicInfo/WSRMService


#################################################################### DOWNLOAD Server configuration
################################################################### ....
# DOWNLOAD Server IP
download.server.ip = [Changed Server IP]

If you make the EWF state Enable or run your client for a long period of time, the client will be running low on its usable memory and you get a low memory message. If you want store important data in its system, store them and restart the system.

How to prevent:

In order to avoid this phenomenon, you can make your client turn off and restarted from time to time—for a day, week or month.

You can make this arrangement using one of the following methods.

1) You can arrange a schedule for client-turn-off times at the MagicInfo-Pro server computer.

2) You can arrange a schedule for client-turn-off times at the client using a menu on its screen.

This message is displayed when the client has been running for a long period of time, or has a large number of temporary storage files or a large amount of content, so that the client has no sufficient space to store new data. If the C drive has no sufficient space and the EWF has been set to Enable, restart the system. If the D drive has no sufficient space, delete some of the content that the client had received from the server before.

How to prevent:

If the client has too many temporary files from a long period of usage, make the EWF state Enable. To keep the client’s available memory enough, arrange a daily, weekly or monthly schedule for clients to restart its system when it has no content to display.

You can arrange a schedule using one of the following methods.
1) You can arrange a schedule at the MagicInfo-Pro server computer.
2) You can arrange a schedule at the client using a menu on its screen.

If a client’s Schedule Server and Connection Name settings are not the same as those of its server computer, you cannot connect the server to its clients. Check the client’s Schedule Server and Connection Name fields. (Refer to 3.2.2)

Step 1. At the client, on the system tray, select the MagicInfo Pro icon and right-click it to display a menu window.

Step 2. Select Setup in the menu.

Step 3. In the Setup dialog box, click Connection and check the Schedule Server field.

If the server and a client are on the same subnet, select Automatic Connection using server name. If not, select Direct connection using IP address and type the server IP address into the box.

Step 4. Check the Name field in the Set up dialog.

If the Schedule Server has been set to Automatic Connection using server name, type the same names as those the server has in its Server and Client boxes.

If the server computer and its clients are not in the same time zone, the clients do not run a schedule disseminated by their server because they have different time clocks. Set the same time zone for the server computer and its clients.

How to prevent:

In order to synchronize the clocks of the server and its clients, set up a time server (NTP server) and synchronize the clocks using Windows Time Service.

This phenomenon occurs when the resources (executable files or codecs) needed to run specific files have not been installed in the client. For video files, install appropriate Codecs, and for other type of files, install appropriate viewer programs.

Check if the EWF state is Enable. If so, you can apply settings you make to the system only by entering the Commit command.

1st solution:

Step 1. At the client, click the MagicInfo Pro icon on the system tray and right-click it to display a menu.
Step 2. Select EWF in the menu.
Step 3. In the EWF dialog, go to EWF State and check the Current State field.
Step 4. Change the setting, and go to EWF command and select Commit, and then click OK.

2nd solution:

Step 1. Click Start, click Run, type cmd, and then click OK.
Step 2. Type ewfmgr –all, and verify that the C drive has been set to Protected Volume.
Step 3. Type ewfmgr c: -commit, and save the change.

Check the IP address of the client and make a try to connect to the client through the VNC Viewer. Type Alt+F12 to get into the desktop, and there do what you want.
