When you use Network License mode, it might be necessary to delete licenses previously added. This is done with a program named Wlmadmin.


  • 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-Tools package can be downloaded from the Download page


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

  • Start WlmAdmin.exe 
  • 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


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

  • 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.
