Overview of Tsver
The Terminal Services Version Limiter (Tsver) tool is available in the Microsoft Windows 2000 Server Resource Kit. Tsver is an administrative tool that you can use to turn on or turn off Terminal Services client version checking, and to edit or to enforce client version policy numbers. This tool provides a way for you to control which clients can connect to the server based on the client version.

With Tsver, you can perform the following tasks:
 * Turn on or turn off Terminal Services client version checking.
 * Specify which client versions are allowed to connect to the server and which client versions are disallowed to connect to the server.
 * Create a custom message to send to users who try to connect to the server with a client version that is disallowed.
 * Record all failed logon attempts in the Security log of Event Viewer.
