The imaging server is a software component of the ZfD server. It enables imaging clients (computers 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 NDS is installed (such as C:\NOVELL\NDS).
In most environments, the imaging server starts automatically when you reboot the server after installing ZfD. With NDS eDirectoryTM 8.5 on Windows, you must start the imaging server manually as follows: from the folder where NDS is installed, double-click NDSCONS.EXE > select the IMGSRV.DLM service > click Start. You might also want to click Startup to configure the service to start automatically each time the server reboots.
Once 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 system tray (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 NDS 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. |
