Installing Exchange 2010 quickly using PowerShell

In Exchange 2007, I typically used ServerManagercmd.exe to quickly deploy required Exchange 2007 parts. In Exchange 2010, when I ran ServerManagercmd, I get the warning that:

Servermanagercmd.exe is deprecated, and is not guaranteed to be supported in future releases of Windows. We recommend that you use the Windows PowerShell cmdlets that are available for Server Manager.

This is replaced by Powershell commands:
Get-WindowsFeature
Add-WindowsFeature
Remove-WindowsFeature

When you run those - you will get an error. Need to run this first:
Import-Module ServerManager

So let's see how fast we can make this go! I am installing for ALL roles. If you need to split out roles, you should read the MS documentation at:
http://technet.microsoft.com/en-us/library/bb691354(EXCHG.140).aspx

You can of course use the Servermanagedcmd -i that they give you, but knowing it's deprecated and I will be doing this 40 times next year, I wanted to know the new way. So here it is!

Install 2008 R2 off a CD/ISO
Set computer time, networking, machine name and domain
Install the AD tools using Powershell
Add-WindowsFeature RSAT-ADDS
Re-Boot
Upon reboot, launch PowerShell as Administrator and copy paste the below (again, this is for MBX, HT, CAS on a single server, check the link above for more detailed pre-requisite planning)
Add-WindowsFeature Web-Metabase, Web-Lgcy-Mgmt-Console, Web-Server, Web-ISAPI-Ext, Web-Metabase, Web-Lgcy-Mgmt-Console, Web-Basic-Auth, Web-ASP, Web-Digest-Auth, Web-Windows-Auth, Web-Dyn-Compression, Web-Net-Ext, RPC-over-HTTP-proxy, AS-NET-Framework, NET-HTTP-Activation

Set the TCP .net sharing service to automatic startup
Set-service NetTcpPortSharing -startuptype automatic

Optional - download and install the x64 version of the Microsoft Office Filter Pack (this allows office attachments content to be searched and indexed.

And from the Exchange 2010 install directory: .\setup.com /mode:install /roles:mb,ht,ca

Now, if you take this and extend it to using PowerShell's remote capabilities, you can prep a BUNCH of 2010 servers quickly!
