Event ID 20097 — RRAS Connection Licenses

Updated: December 16, 2008

Applies To: Windows Server 2008 R2


A client access license (CAL) is required for each client device or user that accesses a Windows Server operating system. Per-server connections to a server are allocated on a first-come, first-served basis, and are limited to the number of CALs allocated to the server. A server that is over its licensed connection limit will not accept remote connections.
