after three weeks holiday, a user failed to logon to the domain.
the user account is not disabled nor locked. The error message poped up
saying making sure username, password or domain name is correct (can't
remember exact message). Reset password did not help. And this only happened
for this user no matter which PC is using. But, after several times failure,
the account became locked.
Can anyone explain what could be wrong?
thanks in advance
