single server - Windows Server 2012 R2 and Exchange 2013 Standard

Exchange mail flow is working but couldn't access OWA
checked IIS and the Default Website is stopped, tried to restart but no luck
clicked to View Virtual Directories and don't see any?
Exchange Back End is running and the virtual directories are there
Was going to recreate the Default Website virtual directories using power shell but it fails to connect
winrm qucikconfig shows it's already setup and running

How to correctly recreate the virtual directories for the Default Website without access to ps?

Thanks

update:
Since I can't connect to Exchange Shell Management, I added the snapin to Windows powershell.
I then ran the following commands, substituting my server name for ServerName:
Remove-OwaVirtualDirectory ServerName\owa (Default Web Site)
Remove-OwaVirtualDirectory ServerName\owa (exchange back end)

This seemed to work, asking me for confirmation, so I then attempted to run the following commands, substituting my server/domain:
New-OwaVirtualDirectory  -InternalUrl https://ServerName/owa -ExternalUrl https://mail. domain.com/owa
New-OwaVirtualDirectory  -InternalUrl https://ServerName/owa -ExternalUrl https://mail.domain.com/owa -WebSiteName Exchange Back End

But this failed for each, returning a message that the website doesn't exist?
Of course they don't, so this makes no sense?

Hi,

I wrote an article in my blog about re-creating owa virtual directories here: http://exchangeonline.in/re-create-owa-virtual-directory-exchange-2013/

See, if it helps
