Techniques are disclosed for virtualizing internet protocol (IP) addresses in terminal server sessions. A client component comprises a layer service provider (LSP) and a name service provider (NSP) that intercept a socket call to associate a port with a socket for a terminal server session. The client component queries a server component for a virtual IP address, and the server component determines whether the terminal server session can use a virtual IP address. Where the session can use a virtual IP address, the server returns a virtual IP address and the client component binds the socket call to the virtual IP address. Where the session cannot use a virtual IP address, the server returns an indication of that, and the client component acts as a proxy for that socket call and any future calls for that socket.

Internet protocol (IP) address virtualization for terminal server sessions

Systems and methods to implement load balancing of connections to a server computer in a server collection are described. The server collection receives connection requests from remote clients over a network. A session broker evaluates one or more load parameters of the server computers in the server collection and, based on those load parameters, determines load associated with each server computer. The session broker redirects the connection requests to the server computer which has a lesser load.

Load balancing in server computer systems

Embodiments described herein are directed to establishing a terminal services (TS) session between a TS server and the client without creating a temporary session. In one embodiment, a computer system receives a user request indicating that a TS session with a first TS server is to be initiated. The request includes an indication that the user is authenticated and authorized to use the first TS server. The computer system searches for any prior TS sessions previously initiated by the user with other TS servers and determines, based on the search, that at least one prior TS session was initiated with a second TS server. The computer system also sends redirection data to the user indicating that the user request is to be redirected to the second TS server to reestablish the prior TS session with the second TS server.

Sessionless redirection in terminal services

Described are techniques for providing an application program interface that leverages the terminal services session broker infrastructure to support third party plug-in applications. In a typical scenario, when a user requests for a connection to access third party plug-in applications, the application program interface may override the session broker logic and interacts with the session broker process to identify sessions or suitable servers to which the user can be connected. The user may access the third party plug-in applications through the identified sessions or suitable servers.
