servers. You also define the NLM configuration. When an Autodesk product
starts up on a client computer, it requests a license from NLM, then returns
it when the product is stopped. Computers running the product based on a
network installation do not require individual activation. For more
information, see Choose a License Server Model (page 4).
A major advantage of a network license is that you can install the product on
more systems than the number of licenses you have purchased (for example,
purchase 25 licenses, but install on 40 computers). At any one time, the product
runs on the maximum number of computers for which you have licenses, so
you get true floating licenses.
Stand-Alone License This license type is for multi-seat stand-alone
installations where a single serial number and product key are used to install
products on multiple computers. With this license type you do not use NLM
to manage product licensing. Instead, installation, registration, and activation
occur on each computer. After the first activation using the multi-seat
stand-alone serial number and product key, activation occurs automatically
for all computers using this deployment, as long as they are connected to the
Internet.
Determine the License Server Model
If you choose the Network License option, you need to know which license
server model will be used to distribute the product licenses. This was specified
as one of the following when the license was purchased:
■ Single license server model. The Network License Manager (NLM) is
installed on a single server, so license management and activity is restricted
to this server. A single license file records 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 NLM on each server that is part
of the distributed server pool.
■ Redundant license server model. Three servers are available to
authenticate each license. With this configuration, licenses continue to
be monitored and issued as long as at least two servers are functional. The
license file on all three servers is the same, and you must run NLM on each
server.
Each of these license server models is described in detail in the Licensing Guide.
It is recommended that you also read that guide before you deploy the product.
