Help w/ WP3 Install on IIS (Almost There)

I used the WP Installer which (ultimately) completed without incident on Windows Server 2003.

After that, I went to
http://my.domain/wp3InstallDirectory/wp-admin/install.php which told me I’d installed WP, already. True. Clicking the log-in button (on that same page) sends me to http://my.domain/wp3InstallDirectory/wp-login.php. It did not force the https, as I’d expected, but I can handle that later.

Upon log in, it sent me to http://my.domain/wp3InstallDirectory/wp-admin/index.php, which was a blank page.

A little Googling showed me I’d encountered the “White Screen of Death”. I’d not activated any plug-ins, so I hacked the code within the index.php to remove the “./” from the beginning of the path in the require_once statements.

For Example:
Before ==> /** Load WordPress Bootstrap */ require_once(‘./admin.php’);
After: /** Load WordPress Bootstrap */ require_once(‘admin.php’);
AND
Before ==> require_once(‘./admin-header.php’);
After ==> require_once(‘admin-header.php’);

At least, now, that one page appears properly, although of course, there’s not much functionality, anywhere else.

Any suggestions? Hints? Resources? Prayers?

NOTE:
Before the WPInstaller completed, we had to *manually* upgrade mySQL to v5.2x which appears to have broken the previous instances of WordPress. I backed up the database beforehand, and imported it into the new instance, but to no avail. Maybe it’s related to the “real” problem; maybe not. I dunno.
