# License Manager Installation

A License Manager program need not run on a file server system or any specific hardware server. Any computer that meets the requirements is acceptable. Realistically, a system running on Pentium Processor 3 (or higher), 550 MHz and having 128 MB RAM is a good choice for measuring stress data.

The License Manager can be installed and run on multiple computers (see ). It can be installed on any computer, even a computer that is used to run one of the licensed applications. The application running on a client may choose any available License Manager with a valid license code for that client.

Installation Instructions

- You may install the Sentinel RMS License Manager using its installer (provided by your vendor or can be downloaded from the SafeNet web site at http://www.safenet-inc.com).
- We do not recommend having different versions of the License Manager co-existing on a system. If you already have an older version of the Sentinel RMS License Manager installed on your system, uninstall it before installing the new one.
- To uninstall the License Manager, look into the Control Panel > Add or Remove Programs option for the entry Sentinel RMS License Manager <version> under the list of programs.
- If you have upgraded the earlier version server with the newer one without uninstalling the former and now want to uninstall the same, then it is recommended to remove both the versions of License Managers (newer version first).
- By default, the License Manager is installed at the following path on Windows: <OSDrive>:\Program Files\Common Files\SafeNet Sentinel. However, you may change it when prompted for it during the installation process.

Manually Adding Sentinel RMS License Manager Entry in Windows Firewall

If the Sentinel RMS License Manager is not added under the Windows Firewall exceptions, the communication between the clients requesting licenses and the RMS License Manager cannot take place.

The Sentinel RMS License Manager (License Manager) installer adds this entry, by default. If you change this default addition during the installation, you need to manually allow the Sentinel RMS License Manager (License Manager). Here are the steps:

1. From the Start menu, point to Settings and click Control Panel.
2. Double-click Windows Firewall.
3. Click the Exceptions tab.
4. Click the Add Program button.
5. Browse for the License Manager executable (lservnt.exe). It is installed at: <OSDrive>:\Program Files\Common Files\SafeNet Sentinel.
6. Click OK. You will find the lservnt.exe listed under the Programs and Services list. Make sure that the checkbox alongside is kept selected.

License Manager Setting Up - Notes

Here are few recommendation that you can make use while setting up the RMS License Manager:

- The computers on which License Managers run should use static IP addresses rather than dynamically allocated IP addresses (DHCP). In fact, redundant License Manager computers must use static IP addresses.
- Client computers should directly contact the License Manager that services the licenses used by that client. The LSHOST and LSFORCEHOST environment variables or the lshost file can be used to do this.
- Client computers should contain a hosts file that maps IP addresses to the host names of the computers on which License Managers reside; this speeds up contacting those License Managers. For certain supported versions of Windows, this file is probably located in \System32\a\Etc. The file itself contains instructions on entry format.

The License Manager can communicate over a single IP address only on a multi-home PC. You do not have choice to specify any particular IP address for use by the License Manager. If the IP address to which License Manager is bound becomes unavailable for any reason, then the License Manager needs to be restarted to allow using any other IP address on the system.

- We recommend restarting the License Manager in the case of time zone change.

Checking Presence of the License Manager

On Windows, you can check the presence using the following steps:

1. From the Start menu, point to Settings and click Control Panel.
2. Double-click Administrative Tools.
3. Double-click Computer Management.
4. Under Services and Applications, select Services. A list of the services installed on the system is shown on the right-side pane.
5. Look for the Sentinel RMS License Manager entry.
