Microsoft → [XP Pro] Login fails after SP2

After I have updated to SP2 I was unable to login with my account. I swear I remember my password very well ! but when I hit enter after typing my password it prompt "invalid parameter....., please contact your administator for techinical......."

Then I went to the extreme by trying to reset the password using ntpassword but fail. Tried to copy the sam file and crack with LC5 but no luck too.

Anyone please, suggestions needed. My douments cannot be back up, its very important to me.

Thanks in advance.

Login fails where, to the internet site, computer/network etc? Work or home computer?

What is the exact error message. Can you access computer in SafeMode

Are you logging on as "administrator"? If not, at the login screen press ctrl-alt-del twice, which will bring you to the Windows 2000 classic logon screen - assuming you haven't made a password for "administrator", type that in and press enter.
