My company has decided to send me to classes for exchange server. We run exch55 and it's either take those,which are hard to find, or take exch2k classes. They want to install exch2k on an existing nt4 domain. can i just take a win2k server with exch2k and after performing all of the right moves install it on my domain? Or does the fact that i now have a 2k server running active directory services now require that i make it my pdc? help!! what is the best route?
