CA eTrust ITM 8.1:

This section will cover three installation scenarios as in the following:

  1. Systems downloading updates directly from the Internet.
  2. Systems downloading updates from the local distribution server(s).
  3. Systems downloading updates from both - local distribution server(s) and the Internet.

Scenario 1:

On a system where you are running eTrust ITM 8.1, you will see the following screen which will have the source server pointing to

Moving forward, iSheriff will be hosting all signature updates for eTrust ITM 8.1 on a new domain The above Download Source > Server Settings must be changed and pointed to the new domain to ensure that you continue to receive updates.

Once downloaded, please extract the zip archive and run the script file itm_update_8_1_675.bat.The script must be executed on all systems that are running eTrust ITM 8.1 including eITM Servers, eITM Clients, and eITM Re-Distribution Servers using a local system administrator account since it makes changes to the Windows Registry as well as starting and stopping some eITM 8.1 Services.

Once the script has successfully completed, you will see that the update server has been changed to as shown below and thus subsequent eITM 8.1 updates will be downloaded from this location.

Scenario 2:

If your system is configured to get its eITM 8.1 updates from your own eITM 8.1 re-distribution server(s), it will continue to get the eITM 8.1 updates from your eITM 8.1 re-distribution server(s). In this case, there is no need to execute the script on such a system.

For example, in the following screenshot, the system is configured with two distribution servers.

Scenario 3:

If you have a system that points to your local distribution server(s) first, then as a fall-back method where your update server list may look as in the following, the script will only change setting to and leave rest of the configuration in tact.
