maybee it is because there is no apache on win 2003. On osx you have apache, on win 2003 you have iis.
But, what happens to your pull down menue when you install apache ( http://httpd.apache.org/download.cgi ) on your 2k3 machine before installing fm server?
I didnt try it out before, because there is no real need to have apache on a 2k3. You have iis, i think it is the better choice. So be careful what you do.

Thank you for your post.
In the FileMaker Server 10 Getting Started Guide, the system requirements show Apache for Mac OS, and IIS for Windows. You will be unable to use Apache with FileMaker Server on Windows.
