How to delete a license from a License Server?

Foreword

When you use Network License mode, it might be necessary to delete licenses previously added. 

This is done with a program named License Manage Administration, also known as Wlmadmin.

Prerequisites

• You have installed the License Server
• You have prepared WlmAdmin program on a computer that has network access to the License Server
  License Server itself is the simplest choice.
  WlmAdmin is part of Sentinel RMS Tools package.

SentinelRMS x.y.z-WlmAdminpackage can be downloaded from the Download page

Procedure

From the license server, or from any computer in same network: 

• Start WlmAdmin.
• Find the server (if necessary, add it to the defined server list) 
• Find the license feature name.
• Find the license.
  You can check the current state, the start and end date if there is more than one license for the same license feature name.
• Right click on the license, then click on: Delete license from server and it’s file.

Check if the license has been correctly deleted

Alternative

The license file default name is lservrc and the default location is: 

• Sentinel RMS 10.6: %CommonProgramFiles(x86)%\Thales\Sentinel RMS License Manager\WinNT
• Sentinel RMS 10.1: %CommonProgramFiles(x86)%\Thales\Sentinel RMS License
• Sentinel RMS 9.6:  %CommonProgramFiles(x86)%\SafeNet Sentinel\Sentinel RMS License Manager\WinNT

So, you can also, after stopping the relevant service, edit the file.
