DCOM & php

Hi. I have a DCOM server working just fine on one machine. On the other machine, I have IIS+PHP4.06 plus I have the server DCOM's typelib on the client. I have tested it through a delphi client program and it works nicely, but I cannot seem to get it working in PHP. I prefer the typelib-file solution to having I client proxy-stub-dll file. I've tried to set the "com.typelib_file" setting in "php.ini" but I doesn't make any difference. It seems like php tries to find the interface in the registry instead of the "com.typelib_file"-path because I get "illegal prog id". Maybe I'm missing something obvious...but there aren't all that many places to look for DCOM+php stuff. Thanks in advance. /Pjer
