Every computer in the ATLC labs requires your eRaider username and password in order to access the computer. Just type your username and password at the sign-in prompt and you should be able to sign in successfully. If prompted for a domain, use "TTU".
Be sure to enter the correct password with your username. It is possible to lock your domain account by attempting to sign in too many times with an incorrect eRaider password. If your account does become locked, it will unlock automatically after 15 minutes as long as incorrect passwords do not continue to be entered.
Please remember that your eRaider username and password are required for access to computers during the training ShortCourses, also.
