This article describes an issue in which users can't get a client access license (CAL) or log on to a Windows Server 2012 R2-based server. A hotfix is available to fix this issue. Before you install this hotfix, check out the Prerequisites section.
Symptoms
This issue occurs when many users log on to the system in a short time.

To fix this issue, we have released a hotfix for Windows Server 2012 R2.
