on some PC's we have problem that the login with windows authentication does not work. For example, the login to my PC does not work anymore. If I log on to another PC with my user data it works. In all browsers (Chrome, Edge, Firefox and Internet Explorer, the login is tried as administrator and not as windows user. My user on another PC works with "Integrated windows authentication". If I switch to "Ask for Windows username and password" I can login with my user on my pc without problems. We have been using the "Integrated windows authentication" feature successfully for a year. Group memberships have not been changed. Does anyone have an idea what I can look for?
