2008 R2 active directory - wrong user name or password on some users

Hi,
I have 2008 R2 active directory environment with one physical DC and VMware virtual backup domain.

I got wrong user name  or password on some users including the administrator  when trying to log on to the DC\servers\workstation.

After reinstall the 2 DC's the system worked for a few days and I got the same problem: users got wrong username and password while trying to log on.

Check workstations and DC´s time. Differences more than 10 minutes would make users can´t logon.

If multilanguage environment, keyboard layout could confuse password entries.

Does this problem persists when you reset the password to some simple one like: passworD1234
?

If problem occurs and you reset the password to some simple one like: passworD1234 - will the problem still persist?

Do you have a multilingual environment?
