I have an issue, I am in a computer Lab and I created a sequence of names in the domain. Once I created and assign a user on all computers. After some days I as administrator couldn't install or login to that computer showing wrong password. But the user can log in.
I don't know what is the issue I thought I was because of duplicate names in the AD and I change the name some time it works sometimes not. And now more computer having the same issue.
