I've been setting up a development server with the exact same configuration as a live server.  Instead of using php 4.3.x I decided to try 5b3.  I use the same php.ini file.

I have IIS set to host two web sites in the following two directories:
c:\inetpub\wwwroot\www.draconic.com
c:\inetpub\wwwroot\www.draconic.net

In php.ini, I have doc_root set to "c:\inetpub\wwwroot" so that files in either of these directories can be loaded.  Yet when I load any php page from either site I get the error "No input file specified".  I am using IIS 5 under win2k using the ISAPI version of php 5b3.

I found that by changing doc_root from "c:\inetpub\wwwroot" to "c:\inetpub\wwwroot\www.draconic.com", I can get the php pages to work reliably for the first web site.  However, this means I get the "No input file specified" error when I try to load pages from "c:\inetpub\wwwroot\www.draconic.net".

With doc_root set to "c:\inetpub\wwwroot" I get the "No input file specified" most of the time, but I found it would occasionally load the php page correctly (maybe that was a caching thing?), or even give me a memory access violation when I tried to use the "include(...)" statement!  I can't figure out what was different when it worked or when it access violationed, but something seems to be seriously broken with doc_root in php 5b3.
