is it possible to build a win2008/exch2007 2 node cluster, based on win2003/exch2003, concepts and use SCR to get the data to another data center for DR purposes? basically I'm asking if I can build a traditionl MS cluster with Win08/exch07 and use SCR.

The old cluster is now called SCC. I'm not sure if you can use both but I think you can.Mark Morowczynski|MCT| MCSE 2003:Messaging, Security|MCITP:ES, SA,EA|MCTS:Windows Mobile Admin|Security+|http://almostdailytech.com

Yes you can.Also, fun fact: there is no more scc in exchange 2010. I'm not sure if that will influence your design any... Mike Crowley A+, Network+, Security+, MCT, MCSE, MCTS, MCITP: Enterprise Administrator / Messaging Administrator
