from microsoft knowledgebase:
CAUSE
This behavior occurs because you did not configure the licensing computer correctly; you have the incorrect server listed as the licensing server.
NOTE: In MMC, LLS may appear to be running, however, when you attempt to cycle the service from a command prompt, you receive the following error message:
Error 1060: The specified service does not exist as an installed service.

RESOLUTION
To resolve this behavior: 1. Start Active Directory Sites and Services, expand the Sites folder, click Default, click First, and then click Site-Name.
2. Right-click Licensing Site Settings, and then click Properties.
3. Change the licensing computer to the primary domain controller (PDC) Emulator in the current domain.
NOTE: The PDC Emulator should be the license server.
4. Restart the computer to start the appropriate services, and then install the licenses.
somethings I've found very helpful in situations like this is:
