Justin, This is not going to be a depth post... but just a post to say how to get yourself rapidly into a good place with SCCM R2. I have been asked a number of times how to gain access to or even build an SCCM R2 environment. As much fun as it is..... and it is fun! It does take a considerable amount of time!
I was chatting to Marco Cibis (PFE Germany) when we were on a training course together in Prague.... Marco is one of our SCCM guru/jedi knights .....
Anyway he sent me a great link for downloading a pre-configured VHD for SCCM
So that was stage one!!! donwload SCCM RTM for an eval..... saved me 10 hours
Next stage is getting SP1 installed and than R2. Now these bits are up on Connect
If you download them than that's really stage two done!!!
Install SP1 you may need to gather 3 updates which the pre-req tool will guide you too and than install R2!
Once your there.... the fun really starts to happen!! Now at first look you may say "hey whats so different" but than the magic really starts! Notice under the software distribution container the new container for Virtual Applications.
