There are exist one computer with installed TFS. I open the admin console, but didn't see any license information. So how to identify which type of license it have?
回答1:
Select the root node on the left panel
If you have a trial, you see a License Expires item, with the option to change the Product key (see Locate or Change the Product Key). This is for the Server license.
Client licenses or CAL are not so simple, they are personal and not all users requires one. See Access Levels and 2015 licensing white paper for details. It is up to the administrator to make sure that users have the proper access for their requirements and license.
