When you setup a web application with SharePoint Server 2007 at port 8082 you will significantly slow down your server.
Other symptoms of doing something wrong: Either the “DC Launcher” service will not start or the web application on port 8082 is down. Unfortunatelly you can start both manually and all seems to be okay.
Reason
The Document Conversion Launcher service is already listing to port 8082. You may not have two listeners to the same port.
Workaround
I guess that the best practice will be to relocate the web application to another port. Simply create a new web application at the desired port (other than port 8082), detach the content database of the old web application and attach it at the new one.
