SentinelLM System Administrator’s Guide 17
Location of the Applications and License Servers
The protected application is installed separately on each client computer. The
license server can be installed and run on multiple computers. In this type of
installation, the application running on a client may choose any available license
server with a valid license code for that client.
It’s possible to install the protected application and the license server on the
same computer. In this case, the license server may authorize program use on
that computer or on any other client computers for which there is a valid license
code. The protected application can be authorized by the license server on the
same computer or by a license server on any other computer. This makes it pos-
sible to locate the server on any computer, even a computer that is used to run
one of the protected applications.
Compatibility
A license server running on a computer with one operating system can commu-
nicate with a client running on another operating system. It’s also possible to
have a client communicate with a license server running on one operating system
today and a license server running on a different operating system tomorrow.
This is all transparent to the user of a protected application. As long as the pro-
tected application and license server can communicate, all license requests will
be correctly handled. There is also no difference between the license codes gen-
erated for license servers running on different operating systems.
In some cases, the application has been designed to work with either stand-alone
or network license codes. In this case you can choose which method of operation
you prefer by providing the appropriate license code.
License Server Structure
The SentinelLM license server is a System Service on Windows NT and Win-
dows 2000. On Windows 95/98, the license server is a background program
(although it optionally can be run in the foreground in a visible window). Under
UNIX, the license server is a background process.
