I have a couple of questions before I fully dive into Exchange. I started to setup the trial software on a test server, I didn't get very far. I tried using the deployment guide, but I still ran into problems. One thing before I go too far, is it possible to setup exchange on a machine as a test server then move it into use when I feel comfortable with it. This would pretty much mean changing the dns, wouldn't it? I know this is possible, but not very well documented. The other question is, is there any better step by step guides out there on setting up, other than the deployment guide? I run a small network for a k-12 school district and we only have about 450 computers and will probably only have around 100 accounts on the exchange box. Most of the deployment guide seemed to focus more on large corporate use. Thanks for any help.
