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

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

           

         • 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

           

      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

           

         • 32-bit:

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

           

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

      

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

      

   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
