How to Configure SSH Server in Windows 2008 server for use in putty?

Hi,

   I am using Windows 7 as hostOS and windows 2008 server (trial) as guestOS. I want to use putty to gain access to GuestOS's SSH.

I want to know the following procedures:

1. Is there any Built-in SSH Server exist in windows 2008 server?
2. If so tell me How to configure SSH Server in Windows 2008 Server and also User accounts for it?
3. How to Use putty in order to connect to Windows 2008 Server's SSH Server.

Note: I have already configured Bitvise SSH Server and successfully using it through putty. but Bitvise SSH Server has limitations in it's usage which is a problem to me.
