Default Server Roles All Necessary?

Hi there,

my installation of ws12e comes with the following server roles installed by default

1. AD CS
2. AD DS
3. DNS
4. File and sotrage services
5. IIS
6. NAP
7. Remote desktop services

To decide with roles are crucial for the use of my server, here's what I want to do with it:

• backup of client pcs
• network shares
• provide group policy for client pcs and users
• remote web access
• log onto the server via a client's remote desktop application
• (at some point, but not now: WSUS - controlling windows update for my client pcs)

I am not really sure of what the individual roles really do so I wanted to ask for your input; what can I safely delete/disable - given my requirements above? The reason I want to do this is speeding up the boot process. Since I own a N40L, suspend-to-RAM is not available. Because of this I installed the server OS on a 60GB SSD and make the server go to suspend-to-disk whenever possible. Sill, it takes a lot of time to operational after a wake event...

Thanks for your input!
