I was facing issues in IIS which is I won’t get the Default website in IIS .This issues i faced while installing SCCM2012 .Here there is tips to solve the issues for creating the Default Web site.

All you need to do is recreate the site, name Default Web Site and point to c:\inetpub\wwwroot.   This at least will recreate the site.  Is this what you are looking to do?”
