The following table provides detailed information about the IP discovery technologies:
IP Discovery Technologies
Table 1-1
IP Discovery
Functionality
Technology
WMI WMI is the infrastructure
(Windows for management data
Management and operations on
Instrumentation) Windows-based
operating systems.
Discovery issues a
remote request to the
WMI service on the
devices identified by the
IP-based discovery task
to obtain information.
Retrieves the OS type
and version, MAC
address, Network
Adapters, and CPU
details of the device.
For more information on
WMI, see the
Web site (http://

Requirements
Because WMI is a
Windows-specific
technology, the
requests generated
from a ZENworks
Server running on
Linux must be routed
to a Windows Proxy
for processing. For
more information,
see Section 2.2,
"Designating a
Discovery and
Deployment Proxy
Server," on page
MSDN
Prerequisites
Microsoft Windows
Management Instrumentation
Service to be installed and
running on the target
Windows device.
Credentials of an
administrator account on the
target device should be
specified as Windows
credentials in the discovery
task. This is required for
connecting to the WMI
Service.
To authenticate by using the
26.
Windows credentials, set the
value of the Network access:
Sharing and security model
for local accounts Local
Security setting to Classic -
local users authenticate as
themselves. For more
information on how to
configure the Local Security
settings, see "Enabling
Classic File Sharing" on
page 83.
Since the Remote WMI
connection establishes a
RPC connection with the
target Windows device, the
TCP ports 139 and 445 must
be allowed by the Windows
Firewall of the target device
for the WMI discovery
technology. For more
information on how to open
these ports, see
File and Printer Sharing
through Windows Firewall" on
page 82.
