I have a network of 160 XP clinents on 3 2003 boxes which is my bread and butter. I also have 2 Emacs , 1 Imac , 1 G4 and a new G5 all in the design dept. Before taking this job the last time I touched a Mac was 1988 and a lots changed. I've read plenty of how to's about adding them into a domain but what am I going to gain by this, am I actually going to lose functionality or cause issues with the macs? It would be great to allow users of the macs access to their home areas on the 2003 machines but is it worth the hassle? I'll split the points if this turns into a debate, I'm not really after a PC\ Mac is best argument, just the facts. Cheers.
