I'm assuming that this is the work of some sort of Trojan or some other virus that was downloaded onto my family’s computer. When starting up Windows XP it takes an extremely long time to get to the login screen. When you click on a user to sign in as, it is asking for a password. Passwords were never assigned to any user in the past. When you click ok without typing anything into the box the screen changes and a notice pops up saying Logon Message The system cannot log you on now because the domain DUNIT is not available. If you hit the ok button you go back to the login screen are and stuck back where you started. I think I can wipe out whatever is causing this using the methods detailed in this thread http://www.techspot.com/vb/topic58138.html which I used before on a different computer but I need to be able to get into windows, at least in safe mode, before I can do anything. I've tried using a boot disk but it just gets me to a command prompt without the local drive loaded so I can't go anywhere. I've also tried booting into safe mode with no luck. Any help is greatly appreciated. Thanks!
