doc-root in php.ini

Apologies if this is a duplicate.... Hi, I've set up and tested php 4.5 on IIS4 on an NT machine. This machine supports several hosted domain web sites and each has it's own IP. My problem is that I specified the Document Root in php.ini, having it pointed at the root of the first web on which I wanted php installed. That worked fine until I went to enable it on the second hosted web site, which then showed the Document Root of the first. Clearing the document_root entry in php.ini (leaving it empty) and re-starting all IIS webs had no effect. The second web still reports the document_root of the first. Can someone please help me to get each hosted web to show it's own root directory ? Thanks, Kevin. --
