Seamless discovery of workstation-installed remote applications from an extranet

Systems and methods for enumerating applications by a remote client computer are described. The applications are deployed in an Intranet. The remote client computer is external to the Intranet. In one aspect, a remote application discovery request is sent to a Web service. The Web service is deployed on a remote applications publication (RAP) Web server in the Intranet. The remote application discovery request is sent to the Web service by the remote client computer via a public network that connects the remote client computer to the Web server. Responsive to sending the remote application discover request, a discovery response from the Web service is received. The discovery response identifies at least one application installed on the Intranet for terminal server (TS) based access by a user of the remote client computer.
