Whenever you move your main server to a new computer, you must use Server Admin to reconnect all the expansion servers on your system to the new computer.

Before you begin

After completing an expansion server installation, the expansion server automatically connects to the main server. You must only go through the steps of connecting your expansion server to your main server if:
  • You entered the wrong connection parameters to the main server during the expansion server installation.
  • You moved the main server to a different computer.
  • You changed the password on the main server while the expansion server was down.
  • You enabled Directory authentication on your expansion server, but your Directory certificate is not signed by a trusted certificate authority.


  1. Open the Server Admin web page by doing one of the following:
    • In the address bar of your web browser, type http://computer:port/Genetec, where computer is the DNS name or the IP address of your server, and port is the web server port specified during the Security Center Server installation.

      You can omit the web server port if you are using the default value (80).

    • If connecting to Server Admin from the local host, double-click Genetecâ„¢Server Admin () in the Genetec Security Center folder in the Windows Start menu.
  2. Enter the server password that you set during the server installation, and click Log on.

    The Server Admin Overview page appears.
  3. If you are not connected to the main server, click Main server connection at the top of the Server Admin window.
  4. Enter the Server address (main server's DNS name or IP address) and Password, and then click Save.
  5. When prompted to restart the service, click Yes.
    While the Genetecâ„¢ Server service restarts, you are temporarily logged off from Server Admin.
  6. After logging back on to Server Admin, if you get the message that the identity of the Directory cannot be verified, click Main server connection.
  7. In the dialog box that appears, verify that the certificate of your main server is as expected, and click Accept certificate.
    IMPORTANT: After being accepted, the certificate is stored in a local whitelist, and you should not be prompted to accept it again. If you are, then you should immediately notify your IT department.
    Best Practice: To avoid the burden of having to accept the certificate of your main server every time someone tries to connect to it from a new machine, only use certificates signed by a certification authority that is trusted by your company's IT.
  8. Click Save.
  9. When prompted to restart the service, click Yes.
    While the Genetecâ„¢ Server service restarts, you are temporarily logged off from Server Admin.


The expansion server is now connected to the main server. The two servers will remain connected, even when you change the certificate, on either one or both of the servers, as long as the two servers are connected while the change is being made.
