Device statuses (offline / online) are not displayed correctly on the core server.
Mostly, if all devices are affected in the console, the issue is caused by a false proxy server setting on the core server or has a different network related cause.
Steps to troubleshoot:
The general benefit from following these steps is to be able to investigate each phase of the process, that is done by the LAndesk Console (console.exe *32 process in task manager) when a device is clicked in network view. If the issue is related to a network / proxy / firewall configuration problem, at least some of these steps should fail:
!!!Before testing, please open Task MAnager and check the account, which runs the "console.exe *32" process. Then please open a cmd line and type "whoami".
Please ensure, that the result of the command is the same, that you can see in task manager!!!
Please set "Use DNS" in the Landesk Console to disabled (Configure > Agent status options...) then,
Please open the following page from the core - Client IP should be the IP of the test client
If successful, you should see a small XML page with the DeviceID in it
Try to ping the IP address of the test device
Please issue the command: "telnet [IPaddress of the testclient] 9535"
(If the telnet client is not installed on the core, please install it in features. It doe not influence LAndesk in any way)
The command line window should display random characters if successful.
This step checks, if the TCP port 9535 is opened on the client
Please unset "Use DNS" in the Landesk Console to enabled (Configure > Agent status options...) then
Please open the following page from the core - machine-name should be the hostname of the test client
If successful, you should see a small XML page with the DeviceID in it.
Proceed with Step 2 + Step 3 according to Test1
If any of the above steps fail, the error message you get should point you to the right direction, where to investigate further.
