Howdy Ned, hope you're doing well.
I have been testing SMB over Quic on server 2025 for some time now. Haven't had any real issues. My main test has been from my own machine, which is native entra-joined, so AD isn't aware of it of course. My user account is hybrid, however.
This has worked fine, I can connect via unc or drive mapping to \\server.externaldomain.com\share$ without issue. A couple days ago I configured WHFB on my machine - previously was just using password auth to log in. I've now noticed that if I sign into the machine using Hello, the smb over quic share cannot be accessed. If I sign out and back in via password, it works fine again.
When it fails (after using Hello) I get "The system cannot contact a domain controller to service the authentication request. Please try again later."
Any thoughts on what (if there's anything) I can do to alleviate this? I'm guessing it's something to do with password auth working with hybrid password hash auth, but maybe hello doesn't have something compatible to pass onprem? (over my head!)
Thanks!
