Network License Manager

This licensing approach requires some software to be installed on a computer that is available using TCP/IP to any other computer which will run the actual Structural Engineering Library programs. The remote "client" Computers will request and obtain authorization to run from the "Network License Manager".  In the simplest situation both the Network License Manager and running program could be on the same computer, but more commonly the Network License Manager will be on a central server and various clients attached to the company network will be running the software.

The current design requires that all computers (servers and clients) that wish to use the system must be running the TCP/IP protocol and that it must be configured correctly. On Windows platforms you can determine if TCP/IP is available by selecting the "Network" option in the control panel and choosing the "Protocol" tab. You should see "TCP/IP" Listed. If you the highlight the "TCP/IP" protocol and then click the [Properties] button you can configure the protocol on your computer. As a minimum you must have a unique "IP" address for each machine on your network.

The ENERCALC Network License Manager used what is called "subnet broadcasting" to talk between the clients and the License manager. This is a simple and fast way for programs to locate and "talk" to one another across a local network.
