Jeremy: Seems I can't log into my work account today. Have you had any problems today with logging in?
John: No. My one seems to be working fine.
Jeremy: Strange. My one keeps on saying - no such user.
John: Are you sure you're typing in the right login and password?
Jeremy: Yeah, I checked it's definitely the right user name and password.
John: I can't help you much on that one then. Maybe ring tech support and see what they say.
Jeremy: Oh joy! Here comes 45min of hanging on the phone to speak to some numpty that probably won't solve the problem.
John: Yeah, but what else can you do?
Jeremy: True! I guess I better brace myself and ring the helpdesk. I've think they've grown to hate me with all the problems with that account. 
Jeremy cannot log into his work account. He is dreading the prospect of having to call tech support.
