How does RD Licensing base their Licensing fees? 

By device is the way to go.

What is the fee for each IIS Website or are they unlimited? 

What is the fee for each RD Connection Broker High Availability SQL Connection String or are they unlimited?

Hi,

Regarding Microsoft Licensing fee related query, I strongly suggest you contact Microsoft Licensing support to get more professional and legal support:

Locate the Microsoft Clearinghouse Telephone Number for Your Country or Region
