You can use the
VisBuildPro Project action's
Remote tab to launch a Visual Build Pro build on a remote server. See the
Server.bld sample for a demonstration.
Another option is to setup a web front-end to the build server and allow users to launch builds from that. This is demonstrated by the WebLauncher ASP.NET sample:
