With both Mac and Windows computers, a unique GUID is created by the McAfee Agent that identifies and distinguishes each computer within the ePO database. This can cause an issue when the computer is imaged because multiple computers with the same agent GUID will cause identification issues with ePO. To resolve this, the unique GUID must be removed prior to the computer being imaged. When the GUID is removed, the following process occurs:

To allow the McAfee Agent to correctly function in this environment:

  1. Build a system with all required software including the McAfee Agent
  2. Just prior to imaging the system these registry entries should be deleted:
    • [HKEY_LOCAL_MACHINE\SOFTWARE\Network Associates\ePolicy Orchestrator\Agent\Agent GUID]
    • [HKEY_LOCAL_MACHINE\SOFTWARE\Network Associates\ePolicy Orchestrator\Agent\MAC ADDRESS]
    • Right-click MAC ADDRESS and select Delete.
  3. Run Sysprep, Ghost etc.
  4. The image should be taken
  5. An imaged computer is built and its names is changed
  6. The imaged computer is introduced on to the network.
  7. The agent starts up and checks the registry.If it does not find a registry entry for AgentGUID, then it will generate an agent GUID and register the computer as a new node in the ePO server database.

To resolve this issue on a Mac, follow the procedure below.

Solution

To remove the GUID, modify the registry.ini file as follows:

NOTE: The steps below must be performed with the user logged in as root.

  1. In the Finder, click Go, Computer.
  2. If your VirusScan installation uses the NWA (Non-Windows Agent), browse to Library, NETAepoagt, scratch.
  3. If your VirusScan or McAfee Security for MAC installation uses McAfee Agent 4.x, browse to Library, McAfee, cma, scratch.
  4. Double-click registry.ini to open the file in TextEdit.
  5. Locate and delete the following line: AgentGUID=sz{XXXXX-XXX-XXXX-XXXX-XXXXXX} (where XXXXX is the unique GUID for that computer).
  6. Click File, Save. NOTE:If you are not logged in with root permissions, you will not be able to save the file.
  7. Close TextEdit.

Now you can create and deploy the image of this computer. On the first restart of the computer after the image is deployed, the GUID will be re-created by the agent. This also applies to any computers to which the image has been applied.
