where can i get 2003Server R2 64 bits?

Hey guys, i'm now preparing for the exchange 2007 exam and it apparently requires 2003 server r2 64bits. I can easily find 2008 server, and the manual says it is ok but still i wanted to go by the book.
Do i really need to ? Or should i use the 2008 server eval?

Have you looked on the VMWare Virtual Appliance page?
I would just use the 2008 eval. I cannot imagine that there will be a huge bonus for you to find a 2003 x64 eval.

yeh i know, but the problem is that the manual also says that all the study will be based on exchange 2007 64 bits .... these requirements are killing me ! aas there seems to be no easy way of preparing the labs, has anyone took this exam? Do i need to care about which version of the OS i will be using?
Doesn't make a difference whether you use 32 or 64 Bit for your studies. The main difference in using a different architecture are hardware limits such as RAM.
The reason the book "demands" 64 Bit is that the 32 Bit version is not supported by Microsoft for production environments.
The software, i.e. Exchange, is the exact same, there aren't any features in 64 Bit you'd miss in 32 Bit ...
It's sad (and actually a bit dumb) taht we can't use exchange server 2010 to complete mcsa, even because, 70-236 will retire next year ...
