When the license expires, the Enterprise dashboard service stops working and if you manually try to start, it will force close itself automatically.
If you go to the enterprisedashboard.log you will find out the error "license is not valid".
In the {{LISA_HOME}} directory, there is a file called devtestlic.xml. In the XML file there is a tag <validuntil> that tells you the date till which your current license file is active.
I tried changing the date manually and tried running the Enterprise Dashboard service again but CA is clever enough to not let that pass through .

Hope this helps.
Thanks.
