As for the actual discovery process, nothing has changed:

• Workgroup mode license servers must be in the same local subnet as the terminal servers to be discovered automatically.
• Domain mode license server will be discovered automatically provided the license server is installed on a domain controller.
• Forest mode license servers will always be discovered automatically by terminal servers as an entry for the terminal server is made in the Active Directory site object (just as in Windows Server 2003). Microsoft recommends using Forest mode for most implementations.
• A license server installed on the same server as the terminal server itself will always be discovered, regardless of mode.

so the licensing server can be in work group mode
