I don't duplicate the web content about NTPASSWD but it's what I use to solve the password issue. Link to that -> http://home.eunet.no/pnordahl/ntpasswd/
Tusesday the computer worked fine. Wednesday morning after turning on the computer, TrendMicro anti virus showed a virus was detected. AVG free antivirus was blanched out/inoperable. All system proccesses were disabled. I had to set the system proccesses to automatic and start them. Outlook looked/looks blanched except for horizontal lines. I tried repairing the OS using the Win XP CD. It asked for the admin password. It would not take the local nor the domain admin passwords, blanck passwd nor user passwd worked. Any suggestions on how to repair the OS or what happened.
