Overview
Terminal Services License Server Viewer (LSView) is a GUI tool that displays information about all available Terminal Services license servers in the current domain and current site of the computer. It is useful for monitoring and logging the status of license servers.
LSView displays the following information:
The names of all license servers in the current domain and site. This includes new license servers added to the domain and all license servers from the current Active Directory Site within the domain.
The types of all license servers in the domain. There are two types of license servers, Enterprise License Servers and Domain License Servers. The Workgroup License Server type for workgroups is Domain. It is important to know the type of license server when troubleshooting.
The date and time each license server is available. By default, LSView updates server availability every five minutes.
This update addresses the following issue:
Added support to log discovery operations from Windows 2000 and Windows Server 2003 License Servers
