Directed primarily at Steven but anyone with the knowledge is invited to answer.
Are there any problems running SBS 2003 R2 on 64bit hardware? I have been forced into an early purchase but would have prefered to wait for Cougar. The idea is to run with SBS 2003 and then Swing when SBS 2008 is RTM. Alternative is to install Windows 2003 R2 SP2 64bit and Exchange 2007 way before I am ready to play with E2K7.
