mail() function not working

I'm using PHP4.0 with IIS and i'm trying to send a mail.
The code is as follows

mail("me@domain.com","subject","message");

then the error comes as follows:

Warning: Failed to Connect in E:_3000_Php4projectxt_Compose.php4 on line 2

Please help.....

Hari,

Since this is an NT environment, you should make sure that your e-mail settings in php.ini are correct. It usually defaults to a sendmail type system.

Thank you for your response to my question. We didnt do anything with the php.ini file in the server.

//Original

SMTP = localhost ;for win32 only
sendmail_from = me@localhost.com ;for win32 only

Please send me the details what i have to do with this.
