Check to see if you are running a service called enstart.exe. If so, your company is running Encase Enterprise Edition and there is no way you are going to get Encase to stop using 4445 unless your support staff is willing to change it. I would change your jboss serverbindport to something else. If you can't find enstart.exe or this is a personal computer, try TCPView. It is part of the Sysinternals Suite (http://technet.microsoft.com/en-gb/sysinternals/0e18b180-9b7a-4c49-8120-c...) by Microsoft. The Local Address will be your ComputerName:4445. It will tell you what process, the process ID, and if you double click on the process it will tell you where it is located on the Hard Drive.
