Try tracing your machine with Process Monitor. Look for network traffic. You can set a filter for "Operation contains tcp" to see what programs are issuing network calls. Procmon will capture a lot of data. You might also be able to set up a filter for "path contains stora.home" or "path contains whatever-the-ip-address-is".
