[support] Drupal + IIS + windows

Hi people, I want to set up drupal in a windows + IIS environment and I want the user not to have to log in I want drupal to automatically knwo who they are. I am reading all kinds of stuff but some how I am not installing them correct because they do not work Drupal + IIS + Windows and the user did not have to login because its information was automagically pass to drupal. Did any of you people get this to work? Thanks, Nestor :-)
