Endpoints show duplicate Endpoint ID in the Endpoint Application Control (EAC) 2.0 management console

    • Updated:

    • Product/Version:
    • Endpoint Application Control 2.0
    • Platform:
    • Windows All
Summary

Deploying endpoints from a VM Snapshot as in Citrix Provisioning Services (PVS) will use duplicate AC Agent Endpoint ID, also known as the Universally Unique Identifier (UUID) when registering to the EAC Management Console. When this happens, the AC Server is unable to distinguish agents that are installed on duplicate Windows systems where the UUID remained unchanged.

To change the endpoint’s UUID:

  1. Upgrade AC Agent software to Hot Fix Agent Build 1237. Call Technical Support to request for a copy of this hot fix.

     
    You may choose to upgrade to TMEAC v2.0 Service Pack 1 Patch 1 Build 1550, which already includes Hot Fix Agent Build 1237.
    1. Download and extract the tmeac_20_win_all_hfb1237.zip file to a local folder on the endpoint.
    2. Use the hot fix to install or upgrade the AC Agent software with any of the following methods:
      1. Using MSI Package (recommended when upgrading an existing agent)
        Open Command prompt with administrator privilege and run the following command:

        • 64-bit

          msiexec /i AcAgentSetup_x64.msi REINSTALL="ALL" REINSTALLMODE="vomus" ServerHost=serverIP:port or hostname:port /norestart /qn /l*v C:\temp\AcAgentSetup_x64.log

          64-bit

        • 32-bit:

          msiexec /i AcAgentSetup_x86.msi REINSTALL="ALL" REINSTALLMODE="vomus" ServerHost=serverIP:port or hostname:port /norestart /qn /l*v C:\temp\AcAgentSetup_x86.log

          32-bit

      2. Using Setup Package EXE (recommended only for new AC Agent Installation)
        Open Command prompt with administrator privilege and run the following command:

        • 64-bit:

          AcAgentSetup_x64.exe ServerHost=ServerIP:port or hostname:port

          64-bit

        • 32-bit:

          AcAgentSetup_x86.exe ServerHost=ServerIP:port or hostname:port

          32-bit

  2. Renew endpoint UUID.
    1. Add a REG_DWORD “GenerateMachineUUID” and then reboot, or do an AcAgentService restart to change endpoint UUID value. Open Command prompt with administrator privilege and run the following command:

      REG ADD "HKLM\Software\TrendMicro\Endpoint Application Control Agent\CDT" /v "GenerateMachineUUID" /t REG_DWORD /d 1

      add registry entry

      Alternately, you can use the registry editor (regedit.exe) to add “GenerateMachineUUID”.

      regedit

    2. Use the “uuidgen=yes” switch in MSI Package install/upgrade command. Do this if you do not want the machine to reboot. However, this will trigger an Inventory Scan after the command runs successfully. Open Command prompt with administrator privilege and run the following command:

      msiexec /i AcAgentSetup_x86_64.msi REINSTALL="ALL" REINSTALLMODE="vomus" ServerHost=10.10.223.73:4343 /norestart /qn /l*v C:\AcAgent_x64.log uuidgen=yes

      msiexec
