Possible Cause: The addresses changed after discovery was complete, so discovery has not discovered these machines.
Action: If the addresses have changed after the first cycle of discovery is completed, it might take time to discover the changed information again, depending on the size of the network. Use file-based discovery to refresh the information immediately. For more information, see "File-Based Discovery" in "Understanding Network Discovery and Atlas Management" in the Novell ZENworks 6.5 Server Management Administration Guide.
Possible Cause: The addresses have been changed after discovery. The old and new addresses are displayed together.
Action: ZENworks Server Management occasionally displays both the old and new addresses of the machine. Use Database Object Editor to delete the previous address of the machine.
Possible Cause: Outdated information about the machines was received from sources like a Traffic Analysis Agent or a router.
Action: If the machine is not SNMP-configured, it was possibly discovered because of a Traffic Analysis Agent. Try unloading and reloading the agent on the segment where the machine was placed previously. Reloading the agent deletes the old address and enables discovery to retrieve the new address.
Possible Cause: The SNMP information of the machine is displayed incorrectly.
Action: If the machine is SNMP-configured, check the SNMP information of the machine by performing the following tasks:
Launch the MIB Browser from the ZENworks Server Management console.
Specify the IP address of the machine.
Select the MIB-II ipAddrTable in the IP group (iso.org.dod.internet.mgmt.mib-2.ip.ipAddrTable.ipAddrentry.ipAdEntAddr).
Specify the SNMP READ/GET community string.
Click Tree Walk.
If you get any results at this stage, check if the IP address of the server appears in the list. If it does not, correct the IP address of the server and wait for the address to be discovered in the next cycle.
NOTE: You can use the Database Object Editor to edit the information. Select Prevent Deletion by NetExplorer to retain the information in the database .
