TFS Event 3079 occurred. This is raised by the licensing mechanism when the Microsoft Product Code (MPC) license is unknown or invalid or the PID value does not fall within a known range.
This could be caused by corruption in the licensing data.
Check the license to make sure it’s a valid license and isn’t a beta key.
