I really hate when I forget to try the easy/quick fixes.
I just spent 45 minutes troubleshooting Ansible connection issues to servers.
First one - someone removed the user from the local admins group on the server. Why, I have no idea.
Second one - I just had to run 'winrm quickconfig' to resolve the access denied issue.
Literally took 5 seconds to fix each one, but I went down rabbit holes first.
Horses, not zebras...
