Imaging Server (Imgserv.nlm or .dll or .dlm)

The Imaging server is a software component of the Desktop Management server. It enables imaging clients (workstations that are booted from an imaging device) to connect with the network to receive imaging services, including:

The imaging server modules are located on a NetWare server in sys:\system or on a Windows server in the folder where eDirectory is installed (such as c:\novell\nds).

In most environments, the Imaging server starts automatically when you reboot the server after installing Desktop Management. With eDirectory 8.5 on Windows, you must start the Imaging server manually as follows: from the folder where eDirectory is installed, double-click ndscons.exe, select the imgsrv.dlm service, then click Start. You might also want to click Startup to configure the service to start automatically each time the server reboots.

You can use the following parameters with the Imaging Server:

Parameter Description

-i:ip_address

Used in a clustering environment to specify the IP address of the virtual server. This parameter is automatically set during installation in a clustering environment.

You can also use this parameter in a multiple-NIC environment to bind the Imaging Server to a specific IP address.

-s:DN

Used in a clustering environment to specify the DN of the virtual server. If the DN contains spaces, enclose the DN in quotation marks. This parameter is automatically set during installation in a clustering environment.

Use the imaging server for the following:


Viewing Information About Imaging Requests

After the imaging server has started, you can view information about the status and results of the imaging requests that it has received from imaging clients. A statistical summary of these requests is shown on the server console (NetWare) or in a window accessible from the taskbar (Windows). The statistics shown on this screen are explained below. All statistics are reset to zero if you restart the imaging server.

Statistic Specifies

Update Requests

The number of imaging requests of any kind that have been received by the Imaging server since it was started. This includes requests that failed, were denied, or were referred to other Imaging servers (see Client Referrals below). Information about each of these requests, such as the source, type, date/time, and results, is logged on the Imaging server as explained in Imaging Server Log (Zimglog.xml).

Images Sent

The number of images that the Imaging server has sent to imaging clients since the Imaging server was started. This includes only images that were retrieved from this Imaging server. See Client Referrals below for more information.

Images Received

The number of new images that have been received and stored on the Imaging server since it was started. This includes images that were received through client referrals as explained below.

Client Referrals

The number of client requests that have been referred (redirected) by the Imaging server to other imaging servers since this Imaging server was started. Such referrals are made only when the client is running in auto-imaging mode and the Imaging server determines from eDirectory that the image to be created or retrieved is on a different Imaging server.

IMPORTANT:  If a client is running in manual imaging mode and it requests to store or retrieve an image on a different Imaging server, the request is denied and an error is returned to the client. Referrals are currently supported only when the client is running in auto-imaging mode.


Starting a Manual Multicast Session

On the server console (NetWare) or in a window accessible from the system tray (Windows), you can start a manual multicast session, see any sessions in progress, and delete sessions. For more information, see Initiating a Multicast Session from Each Client in Multicasting Images.
