When you install Novell ZENworks on a server, the Preboot Service service or daemon (novell-pbserv) makes all Primary Servers an Imaging Server. To avoid confusion, the Proxy DHCP service or daemon (novell-proxydhcp) is installed, but not enabled. For PXE devices to be able to communicate with Preboot Services, this service or daemon must be started on at least one server on each network segment. Exactly how many servers and which specific servers should run this service or daemon is dictated by your network topology. As a rule of thumb, for every DHCP server deployed in your network, you should have a corresponding Proxy DHCP server. PXE requires that the firewall is either turned off or configured pass the DHCP traffic.
For information on setting up management of your devices, see Section 2.4, Deploying and Managing Preboot Services and Section 2.5, Configuring Preboot Services Defaults for ZENworks Imaging.
In addition to the specific hardware requirements for a ZENworks Server, the server used to store image files must meet the following requirements:
Fixed IP Address: When you connect to the Imaging Server during an imaging operation, you must do so using the fixed IP address or DNS name of the Imaging Server.
Enough Space to Store Device Images: Unless you use compression (which is enabled by default) for your device images, they are nearly the same size as the data on the device hard disk, which could be many gigabytes.
If you want to store an image locally (on a CD, DVD, or hard disk) rather than on an Imaging Server, see Using a CD or DVD for Disconnected Imaging Operations and Using a Hard Disk for Disconnected Imaging Operations.
