Programming & Linux Pros, PLEASE help me. I forgot my Win 2000Pro pwd & a byp program shut me down.?

You should never install these programs, they are meant to be run from cd. You have now trashed your 2000 install. Try a repair install by booting from the 2000 cd, at the first prompt select install, at the second select the R repair option. This may not work as it often can not repair master boot record changes, which may have been made by your install.
