Attempting to start the ArcIMS 3.0 Manager application produces: Error "Page Not Found".
Manager, output and website virtual directories have not been created on the Web server.
After installing ArcIMS, you must create virtual directories for Manager, output, and website. A virtual directory is a mapped location on the Web server to a physical path.
See the ArcIMS 3.0 Installation Guide for detailed documentation on how to create a virtual directory for each supported Web Server product.
