If the ".NET Passport Site Directory" is a link, you should be able to go to any ".NET Passport" site and log in to your Passport i.d.. The theory is that .NET Passport lets you log in once and other Passport sites will recognize that you're id has been confirmed good.

Although the Passport site links they offer are likely to be pretty much interchangeable, the possibility - when there's a problem at the site you get info from - that the links may be compromised suggest that you should pick "somebody you know" and confirm that the link sent you where it said it would. If you want to be truly paranoid, you can identify a site, and then do your own manual entry of the site address, to bypass any possible "reroute" of the link.

My hotmail connection doesn't seem to have any problems now, but in the past I've run into demands from hotmail that I log in again, even when my Passport login was already valid. They do seem to have had some trouble with the concept.
