Why do I get an error similar to "Connecting to http://<machine_name> failed - Connection failed (12007)"?
For example, if your SilkCentral installation uses an IIS web server and is installed on the same machine as Silk Performer then replace http://localhost with just localhost and set the port to 80. If you are using the Caucho Resin web server again use localhost but specify port 19120. Note that these are default ports which may have been changed by your system administrator so you should check with them if the ports have been changed. If you continue to get the same error contact Support.
