Hello all, This isn't a Parallels question as such, but enough people here might be able to help me that I decided to give it a go.... I have a client whom I've advised to buy a Mac Pro because for $4500, he can get an almost server-class machine for far less than if he bought a Dell PowerEdge or HP Proliant with equivalent specs (and IMO Apple hardware is just better anyway). What I'd like to do is get him Parallels, and have several Win2K3 Server VM's (file/print/application, ADS, IIS) all isolated for security purposes. Now my question is this: what version of Win2K3 do I need to support several virtualised instances? Enterprise Edition? Standard? Any help would be greatly appreciated.
