My setup is as follows: IIS 4/ZP 1.03/PHP 5.1.4

I'm trying to log in, and if I enter the wrong username/pass it tells me that the info is invalid. So, I know that I'm using the correct login information. However, always brings the login screen back up even when using the correct login information (happens on admin.php and setup.php).

I don't know PHP, but I can get around a little. I can determine that the zp_loggedin() function always returns false. When I bypass the security by forcing this function to always return true, everything works fine. Although this may be a red-herring for all I know.

It wouldn't surprise me one bit if it's something I have to change in my PHP config.

Any ideas?

Correction: IIS 5... typo

For me I originally thought my db password was the ZenPhoto password (like in WordPress), but ZP actually has separate login info in their "zp-config.php".

I originally ignored everything under the "fill in your db info" section, but down lower is the user and pass section.
