It works great when you log in as a user like you normally would on a Windows pc. But on a server you want it to run as a service, starting automatically in the background and/or being managed by the failover cluster without requiring a user to log in.

The solution back then was to use netplwiz autologon. Obviously a hack and bad for security, but fine for a homelab. After googling it now, it looks like some other “solutions” are documented in the GitHub issue about this.
