Forgot the Administrtor password

go to this site and download this boot utility that will allow to to change your admin password.

this has worked on both NT and Win 2000 systems even if syskey is enabled.
hope this helps you.

Several Q's first.

Is this the local workstation or local server administrator account?

Is this a domain controller?

Are there several accounts set up as administrators?

Is this a production or a test environment?

Do you have a current recovery disk?

If you can get me some more info, I can give you a few alternatives.
