Apache DirectoryIndex problem

Running Apache 2.0.48 with WindowsXP

The problem is, that DirectoryIndex in httpd.conf is always ignored, and
works only in .htaccess

I tryed this string:
DirectoryIndex index.html index.htm index.html.var default.html default.htm
both inside the <directory>, and outside.
When i use this in the .htaccess it works.
