Unable to set default date format to MM/ DD/ YYYY

Hi All,

I had problem to set my default web server datetime to MM/DD/YYYY.
For example
Respose.write( now() )
it will give me this format dd/ mm/ yyyy.
I know that i can use format to control it.
But i would like to change it at my server setting. I had go regional and languange options to change the datetime format. It stil give me the same result

Pls advise how i can fix it.

Thanks
