To resolve the issue:

Make sure that the agent is online and can connect to the Internet.
  1. Log on to the WFBS-SVC web console.
  2. Click Security Agents.
  3. Locate the missing agent/computer using any of the following:

    • Search Bar - Search using the computer name or IP address of the computer. For more information, read this article: Searching clients in WFBS-SVC.
    • Group Tree Pane

      • If the agent is newly installed, look for the agent under Desktop (Default)/Server (Default).
      • If the agent is previously installed in a Group, go to the Group and locate the agent/computer.
    • Computer Pane

      1. Increase the Pagination settings (computers per page).

  2. Open the Registry Editor (regedit.exe).

    Always back up the whole registry before making any modifications. Incorrect changes to the registry can cause serious system problems.
  3. Go to the following registry hive:

    • For 32-bit OS: \HKEY_LOCAL_MACHIINE\SOFTWARE\Trendmicro\PC-cillinNTCorp\CurrentVersion\HostedAgent
    • For 64-bit OS: \HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\TrendMicro\PC-cillinNTCorp\CurrentVersion\HostedAgent
  4. Double-click the AC registry key and check if it uses the correct/latest Activation Code.

    check Activation Code

    It should show the same Activation Code found in the Administration > License Information tab page of the web console.
