The instructions for setting up a Windows license server is here:
The default Service Name for LMTOOLS is Flexlm Service 1. It's best to customize that name to something more descriptive. This Service Name entry will show up as a Windows Service as well.
If you have configured and setup your license server properly, you will see an adskflex and two lmgrd processes running in the Windows Task Manager. This is an expected behavior in Windows. Using the Task Manager is a very fast way to confirm that the license server is running.
