I am working currently on an IIS server that uses Windows Authentication.

There is a weird problem for me when there are some PCs that when trying to browse to the server - they get a prompt to enter credentials instead of IIS getting that from their windows session (on other PCs - the same user can browse to the site normally - and IIS authenticates them with Windows Authentication - without the need of username and password).

I looked at the event logs - and found that and event #4625 is raised, with a failure reason $$2304.

Any ideas on what can it be? Really struggling with that, cant quite figure out why it happens..

Thanks!

    Not much information here. Platform(s) and browser versions. Are the browsers configured to trust the url. A packet capture can be used to determine if the host is sending an auth header. – Greg Askew Aug 18 '21 at 11:34
  • All PCs are running the same version of windows 10 and chrome if that helps. What info from a packet capture can I get? – davidalk Aug 19 '21 at 06:14
