I take it from the title of your thread that you want to reset a win2000 password.
One way to do it is if you have an "erd" floppy. If you don't have one of those you can use one one these nifty tools found here:http://www.winternals.com/products/r.../ntrecover.asp

hehe it takes a bit of tweaking to get it though...if you have any trouble or want some details PM me.
