Troubleshooting Product Activation or Component Updates Parent topic

This procedure explains how to troubleshoot activating products (Antivirus/eManager, SPS, Email Reputation, Sender Filtering) or update components. To activate Email Reputation, IMSS needs to connect to Trend Micro. This process requires an HTTP query with a valid DNS setting. Therefore, if a DNS server is not available or has connection problems, activation cannot occur.

Procedure

  • Verify your DNS server settings with the following command:
    nslookup licenseupdate.trendmicro.com
    The command should return the IP address of your IMSS server.
    If a proxy server is required to connect to the Internet, verify your proxy settings to ensure the HTTP request reaches http://licenseupdate.trendmicro.com.
  • Verify your proxy settings from the management console.
    1. Go to Administration → Updates.
      The Schedule tab displays by default.
    2. Click the Source tab.
    3. Configure the proxy settings.
    4. Click Save.
