thanks for the reply, but i already tryit out... but i couldn't find the logon.scr .

I have just rememberd that i already tried to recover the admin password once like this, if so, then i forgot to change the logon(what ever i called back then) to logon.scr, this could be a reason why i can't find the file :s

I will try to change the cmd to logon.scr anyway, but it will work again.
Thanks
