yes i wont be just throing everything on and flipping the switch and hopeing, we will be testing over the next month before switching the dns over. I was wondering of anyone doing the upgrade form server 2003 to 2008 and hitting a particular r issue that they can pass to me to avoid, like "dont set this to one with that " or things of that nature. Nothing is more frustrating than to get 20-30 hours of configuring and something you do crashes the OS.
