I have a PHP program that works fine if I am running Apache, but breaks using IIS. The piece that breaks is an exec function call. I am calling exec with a command that pipes 3 programs together and redirects the stdout to a file. When it is run from Apache, it works. When it is run from IIS, it gets an error. Does anyone have any idea what I should be looking at to find the problem? Thank you, Golden D. Blount
