How to recreate all IIS directories on a new IIS 7 website (Including RPC and RPC with Cert) in Exchange 2007

I recently had an issue where my IIS website was corrupt and not operable.  My solution was to create a new IIS website - let's call it "New Web Site" and call the old "Default Web Site".  In this example, our external and internal URL is mail.company.com.  Our Internal server name is "MailServer".  Our NetBios domain name is "NetBiosDomainName", so change all of these to fit your environment.

Here's how it's done-

New-OWAVirtualDirectory -WebsiteName "New Web Site" -OwaVersion "Exchange2007" -ExternalAuthenticationMethods Fba

Set-OWAVirtualDirectory -InternalUrl "https://mail.company.com/owa/" -ClientAuthCleanupLevel "Low" -LogonFormat "UserName" -DefaultDomain “NetBiosDomainName” -Identity "Owa (Default Web Site)"

New-OWAVirtualDirectory -WebsiteName "New Web Site" -OwaVersion "Exchange2003or2000" -VirtualDirectoryType "Exadmin" -ExternalAuthenticationMethods Fba

New-OWAVirtualDirectory -WebsiteName "New Web Site" -OwaVersion "Exchange2003or2000" -VirtualDirectoryType "Mailboxes" -ExternalAuthenticationMethods Fba

New-OWAVirtualDirectory -WebsiteName "New Web Site" -OwaVersion "Exchange2003or2000" -VirtualDirectoryType "Exchweb" -ExternalAuthenticationMethods Fba

New-OWAVirtualDirectory -WebsiteName "New Web Site" -OwaVersion "Exchange2003or2000" -VirtualDirectoryType "PublicFolders" -ExternalAuthenticationMethods Fba

New-WebServicesVirtualDirectory -WebsiteName "New Web Site" -InternalUrl "https://mail.company.com/EWS/Exchange.asmx" -basicauthentication 1 -windowsauthentication 1

New-ActiveSyncVirtualDirectory -WebsiteName "New Web Site" -InternalUrl "https://mail.company.com/Microsoft-Server-ActiveSync" -ExternalAuthenticationMethods Basic -InternalAuthenticationMethods Basic

New-OabVirtualDirectory -WebsiteName "New Web Site" -InternalUrl "https://mail.company.com/OAB"

Set-OabVirtualDirectory -PollInterval "30" -Identity "oab (New Web Site)"

New-UMVirtualDirectory -WebsiteName "New Web Site" -InternalUrl "https://mail.company.com/UnifiedMessaging/Service.asmx"

New-AutodiscoverVirtualDirectory -WebsiteName "New Web Site" -InternalUrl "https://mail.company.com/Autodiscover/Autodiscover.xml" -BasicAuthentication 1 -WindowsAuthentication 1

Set-ClientAccessServer -Identity “MailServer” -AutoDiscoverServiceInternalUri "https://mail.company.com2007/Autodiscover/Autodiscover.xml"

Set-OfflineAddressBook "Default Offline Address Book" -VirtualDirectories "MailServer\OAB (New Web Site)" -Versions Version2,Version3,Version4

Now.. RPC and RPC with Cert.  You probably could just re-install RPC, but if you'd prefer not to here is how I recreated them-

Make a backup of the ApplicationHost.config in C:\Windows\System32\inetsrv\config.

Edit the file in Notepad and copy the following from the previus site to the new site.  DON'T use this text, use the text from your old site "Default Web Site".  Change the name of that section to your new site and paste it in that section of the file.

<site name="<Default Web Site>" id=...>
...
<application path="/Rpc" applicationPool="SomeAppPool">
       <virtualDirectory path="/" physicalPath="C:\Windows\System32\RpcProxy" />
</application>
<application path="/RpcWithCert" applicationPool="SomeAppPool">
        <virtualDirectory path="/" physicalPath="C:\Windows\System32\RpcProxy" />
</application> 
...
</site>

Next, copy the following from the previous site to the new site.  DON'T use this text, use the text from your old site "Default Web Site".  Change the name of that section to your new site and paste it in that section of the file.

Replace the old site with the new one like this-

<location path="<Default Web Site>/RpcWithCert"> --> <location path="<New Web Site>/RpcWithCert">

<location path="<Default Web Site>/Rpc">  --> <location path="<New Web Site>/Rpc">

<location path="<Default Web Site>/Rpc">

Run the Command Prompt with elevated permissions and perform run IISreset.
