I recently had occasion to revisit the Advanced Internet Options. I had a good look at the settings in there to see if there was anything I really ought to change, and I found one called "passive FTP", which according to Microsoft's pop-up help, can be set to hide the computer's IP address from the remote server. Some sites, it says require passive to be turned on, while others require it to be turned off. Most however can handle both, and passive is most secure.

Needless to say, the box is unchecked. I didn't do it, so I assume it's a Microsoft default.

Is this Microsoft being lax with my privacy again, and should I check it, or am I better leaving it unchecked because of compatibility issues?

Any views?
