Hello. I'm hoping someone here with a bit more experience than I have can assist. I upgraded to Lion this morning and everything seemed fine. When I attempted to login to my account (which is an Active Directory account) after the computer restarted, the Lion login screen had a little red dot that said "Network accounts are unavailable". Once I entered my username and password, and then attempted to login, I get a popup telling me that I need to reset my password: " Reset Password You must enter a new password before you can log in to this account. " After entering a new password and clicking the "Reset Password" button, the window shake sand nothing happens. I've tried many times to no avail. I was able to login to the machine with a local account. I then went into the System Preferences > Users & Groups > Login Options screen. There I saw that the Network Account Server had a GREEN dot next to it, indicating that everything was OK. However, after logging out and restarting my machine a few times, I still saw the red dot on the login screen and was unable to login. I've tried connecting via Wi-Fi and via Ethernet to no avail. I am connected to the domain with no issues. Can anyone offer me any assistance in terms of next steps? I'm at a loss here and don't know how to proceed. Cheers!
