14.0 Troubleshooting ZENworks Control Center

An HTTP request is not redirected to HTTPS if IIS is running on the Primary Server

Source: ZENworks 11 SP2; ZENworks Control Center.
Explanation: During installation, the setup checks to see if the default HTTP port (80) and HTTPS port (443) are in use. If the ports are in use by another application (such as IIS), you are prompted to use alternative ports. In this case, you must access ZENworks Control Center via the port it is using and not access IIS.
Action: Although http://Primary_Server_IP_address works if ZENworks Control Center is using port 80, http://Primary_Server_IP_address:### (where ### is the port Tomcat is using) always works.
