The data connection mode can be modified under Internet Explorer as explained below. If you are using a web browser other than Internet Explorer, you may look out for the option to enable Passive/Active mode in the browser's help section.
1) Open Internet Explorer. Under Tools menu, click Internet Options.
2) Go to the Advanced tab. Under the Browsing section, select the check box adjacent to Enable folder view for FTP sites.
3) By default, the Passive mode is enabled. Under the Browsing section, un-check Use Passive FTP to enable Active mode. Click Apply and then OK to save the changes.
