The following three processes manage the distribution and availability of
licenses:
■ License manager daemon (lmgrd.exe). Handles the original contact with
the application, and then passes the connection to the vendor daemon.
The lmgrd.exe daemon is used to communicate with the vendor daemon
only; lmgrd.exe does not authenticate or dispense licenses, but rather passes
user requests to the vendor daemon. By using this approach, a single
lmgrd.exe daemon can be used by multiple software vendors to provide
license authentication. The lmgrd.exe daemon starts and restarts the vendor
daemons as needed.
■ Autodesk vendor daemon (adskflex.exe). Tracks the licenses that are checked
out and the workstations that are using them. Each software vendor has
a unique vendor daemon to manage vendor-specific licensing. As its name
implies, the adskflex.exe vendor daemon is specific to Autodesk products.
NOTE If the adskflex.exe vendor daemon terminates for any reason, all users lose
their licenses until lmgrd.exe restarts the vendor daemon or the problem causing
the termination is resolved.
■ License file. A text file that has vendor-specific license information.
License Files
The network license file you receive from Autodesk contains licensing
information required for a network installation. You obtain license file data
when you register your Autodesk product. For information on receiving your
license file, see
Obtain a Network License on page 77.
The license file contains information about network server nodes and vendor
daemons. It also contains an encrypted digital signature that is created when
Autodesk generates the file.
The license file is located in a network location that you specify when you
save the license file from the RegisterOnce Web page, or using the license
information that Autodesk emails to you. The location must be accessible to
every user who runs the product from a network installation.
