This issue occurs when OfficeScan agents with different IP addresses report to the server using the same MAC address. The server fails to identify the agent as a new agent, and prevents them from registering appropriately with the server because that MAC address is already in use.

To resolve the issue:

  1. Make sure you have installed OfficeScan 11.0 Patch 1 or later.
  2. Open the ..\Trend Micro\OfficeScan\PCCSRV\Private\ofcserver.ini file.
  3. Look for [INI_SERVER_SECTION] and add the following line:

    [INI_SERVER_SECTION]
    EnableCheckClientMacAddress=0

    Where:

    0 = Allows OfficeScan agents to report to server using the same MAC address
    1 = (Default) Prevents OfficeScan agents from reporting to server using the same MAC address

  4. Save the file.
  5. Restart the OfficeScan Master Service.
  6. Perform a manual update on one of the affected machines.
    Any machines with the same MAC address should now appear on the web console.
