If you chose the Network License option, you need to decide which license server model to use to distribute the product licenses.

For the network installation, use one of the following license server models:

• Single license server model. The Network License Manager is installed on a single server, so license management and activity is restricted to this server. A single license file represents the total number of licenses available on the server.
• Distributed license server model. Licenses are distributed across more than one server. A unique license file is required for each server. To create a distributed license server, you must run the Network License Manager on each server that is part of the distributed server pool.
• Redundant license server model. You use three servers to authenticate a single license file. One server acts as the master, while the other two provide backup if the master server fails. With this configuration, licenses continue to be monitored and issued as long as at least two servers are still functional. The license file on all three servers is the same. You must install the Network License Manager on each server.

Each of these license server models is described in detail in the Autodesk Licensing guide. It is strongly recommended that you also read that guide before you deploy the program. You can find Autodesk Licensing guide by clicking the Read the Documentation selection, the Documentation link at the lower-left corner of the deployment wizard, or in the Help system.
