Sbs 2011 in iis mistakenly deleted the Default Web Seite with virtual folders and applications settings, how to get it back?

Question

IIS

Good time of the day!
One bad person (my boss, to be more precise) in sbs 2011 from IIS deleted the default page (Default Web Site) with all the settings. After that, his console and shel stopped clinging to exchange, disappeared from online owa and read. Mailboxes, etc., are no longer created from the sbs console.
The question is, is there an easy way to restore the default web page with the internal structure of the one that was during installation (default)? Or a step-by-step instruction, it is not a problem to restore the Default web Site itself, the problem is to configure the virtual folders and applications that were inside. :-( perhaps there is a script that does everything.
Please help.
