When ever any outside program attempts to access my ip in any form a windows authentication windows shows up on my end. For instance when ever I am on internet and a popup tries to write a cookie to my machine I am shown a windows authentication screen. I thought this was caused by recent installation of IIS but I uninstalled it and the problem still remains. I am guessing this is some kind of error with my anonymous user account but I have no idea how to fix it. Thanks
