Lost Administrator password

[Royd]

The Administrator password on my PC was changed accidently
to an unknown password. It's a pre-loaded Windows 2000
Professional O/S. How can I bypass or force reset the
logon password?

Thanks.

Hi .

You have two options:

1)Take your hard disk and attach to another system having
same OS.Boot the m/c.After loging you just rename the sam
file of drive which you want to reset the password.FOR
RENAME Go to WINNT--->System32---->Config--->Sam file.

Now take out hard disk and reinstall it to your PC.BOOt
THE m/c. IT will ask for admin password.JUST PRESS ENTER.
HERE IT CREATS NEW SAM FILE.

YOU CAN CONTINUE YOUR WORK.

PRECAUTION:ALL OTHER PROFILE OTHER THAN ADMINISTRATOR WILL
GET DELETED.

2)REinstall the OS..........
