WAC, Edge and SSO

[RyanAD]

I've setup Windows Admin Center 1809.5 on a Windows 2016 server. I can access it perfectly fine via Edge and Chrome when I use just the hostname (https://WindowsAdminCenter) but when I try to use the FDQN (https://WindowsAdminCenter.domain.com) I'm able to sign in fine with Chrome but Edge prompts me for credentials. I've uninstalled and reinstalled Admin center but that didn't. I've also added the FQDN to the trusted sites but that didn't work either. Is there something else that I'm missing?

Hello, old thread. You need to add either the site or domain into Local Intranet Zone. Edge does not send credentials automatically to Trusted sites, but to Local Intranet Zone sites.
