This problem only occurs when you set up two servers, and one is running version 8.5 of CMS400.NET, and the other runs Microsoft Search Server.
In this case, the Ektron CMS file helper service is installed to the CMS400.NET server, and the protocol handler file helper service is installed to the Microsoft Search Server machine. If you later install CMS400.NET on the search server, the Ektron cms file helper service is added to that machine. Because both services use the same port, the protocol handler file helper service is stopped. This prevents the crawling of assets on the CMS400.NET server.
On the server that hosts both Microsoft Search and CMS400.NET, stop the ektron cms file helper service and start the ektron protocol handler file helper service.
