The keyserver machine provides network licening services to all ZEMAX clients on the network. The keyserver may itself run ZEMAX, but it does not have to. There is very little computational load placed on the keyserver machine by the keyserving software, but the machine should not be working at close to 100% CPU usage, otherwise it may fail to provide an adequate level of service to the clients. For this reason, if you do run ZEMAX on the keyserver machine, it should not be used for computationally intensive tasks like global optimization, physical optics propagation or non-sequential ray-tracing.

Download the key driver from the Downloads page. Do not plug your ZEMAX hardware key in at this time. Also, if you have protection keys for any other software installed, temporarily remove these keys during the installation (replace them once installation is complete).Run the key driver software on the keyserver machine. You must be logged on with Administrator privileges to do so.

During installation, you will see a screen like so:

Select the Complete option. If you are running XP or Windows Server 2003, you will then see:

You must select YES in order for other machines on the network to be able to see the network key. If you are running any other firewall software, consult its documentation and make ports 7001 and 7002 open to machines on your LAN.

Once installation is complete, plug your ZEMAX network key into a USB port on the keyserver machine. After a few seconds, Windows' USB sub-system will detect the key. The green LED on the key will illuminate. This is an important test: the green LED means not only that the key is getting power, but that the driver software is correctly configured and recognizes the key.

Then start Internet Explorer. Type the following into the address bar:

http://127.0.0.1:7002

The address 127.0.0.1 is the "loopback" address, and means "use this machine". This link will therefore only work when run from the keyserver. You will see:

It is possible that Internet Explorer will have to download Java 1.5 from Sun MicroSystems in order for this display to be seen. 

When you see this screen you know that the keyserver is working correctly and that the client machine can see it. The number under "Hard Limit" should correspond to the number of network licenses you have purchased. Licenses-In-Use is the current number of licenses being used, and is zero when the server sofware is first installed.

If this screen does not appear, and you are using XP or Server 2003, check the firewall settings: 



The Seninel Keys Server and Sentinel Protection Server must be allowed to connect over the network. If you have other firewall or port-blocking software installed, consult its documentation or technical support team. ZDC cannot provide support on firewall-related issues.

You have now completed the installation of the keyserver software on the keyserver machine.
