Thank you for the post.
First, Windows Server 2012 is a tested operating system but Windows Server 2012 R2 is not. Here is the list of tested operating systems and the system hardware requirements:
Untested operating system aside, PID 4 is a system process, so something in the Microsoft Windows operating system is running on the ports.
Was IIS installed prior to the installation?
The installation will enable and configure IIS, so do not enable IIS prior to the installation.
Try the following:
1. Remove the IIS role from Server Manager
2. Restart the computer
3. Delete the inetpub folder (located directory on the C:/ drive)
4. Redeploy FileMaker Server 13
Does deployment now succeed?
Please keep me updated with any progress.
