Yes, SDM requires passive FTP. If SDM is encountering the following error (or something simliar) in the SDM log file:
16:40:59 Error: - System.Net.WebException: The remote server returned an error: 227 Entering Passive Mode (15,192,45,22,168,83)
This type of error is generally due to an issue with a firewall (Windows Firewall, another software-based firewall, a router, and/or a modem).
Here is a small checklist of things that need to be verified:
* Please check that your proxy settings are correct. This is especially important if you have a notebook and/or access the internet from several different networks.
* Please check that HP SoftPaq Download Manager has been added to your personal firewall white list as well as to your corporate firewall's white list. A white list is the list of applications allowed to access the internet by the firewall. It is not always apparent when a firewall (hardware or software) denies internet access to an application, so please consult with your network administrator.
* Please check all applicable firewalls (Windows Firewall, any other software-based firewall, router, modem) for settings that may interfere with passive mode FTP.
After reviewing all of the above, please try running the application again.
