On the license manager server, open the License Manager Tools utility (from Start > Programs > ArcGIS > License Manager > License Manager Tools)
In the Service/License File tab, select 'Configuration using Services'. Click on the 'ESRI License Manager' service to select it.
Click the Server Status tab.
Choose to Perform a Status Enquiry - display everything.
Your license file, listing all the products and extensions you are licensed for and their status will be reported in the window.
To view license availability on a Windows client installation:
Go to Start > Programs > ArcGIS > Desktop Administrator.
Go to the License Manager folder to specify a license manager.

This will display all the products and extensions you are licensed for and their status.
