Yesterday, I came home, and my iMac was off--weird. I turned it on, the login page came up. I clicked on my account name, put in the password. The screen turned white and showed the login screen again. I tried logging on on "other," but same thing happens, probably because the computer account user name and password is the same as my server user name and password. I can log into the guest account, though. I had my internet service changed yesterday, and the phone company guy messed with my router, and ended up clearing the router's name and password, and I have no clue if that is the problem, which is why I cannot log on to my server account. Any clue?!
