As per my knowledge it will change the host name when it communicate with server.
It's been my experience that name changes reflect in ePO upon next communication, especially if internal McAfee Agent GUID remains the same. No need to reinstall anything. If you also uninstall/reinstall the agent, the GUID will be regenerated, I believe, and server settings will come into play to match current systems against "new" clients, configured in ePO at "Detected System Matching" in Server Settings (ePO 5.3).
But in my case it is not changing.
- Post agent communication it is not changing.
- And in some machines post reboot of the machine it is reflecting with new host name but not in all the machines.
"Detected System Matching"
It requires RSD extension to be installed to get this option. What about the ePO if i dont have RSD extension ?
Please note that a name change on a Windows computer will take effect after reboot, so a name change will not reflect in ePO until after the client reboot, then an ASCI will update ePO with the name change.
Make sure you don't have duplicate GUIDs. Check agent GUID on the client (if MA4.x see HKEY_LOCAL_MACHINE\SOFTWARE\Network Associates\ePolicy Orchestrator\Agent) and check against ePO record. If different, you will not see name change in ePO record you're looking at. Duplicate GUIDs can also cause major problems.
