My company is setting up a subcompany. They want it to have its own domain and email address. It is going to need access to some resources on my network. I know I can set it up as a sub-node in my AD, but how does that work with exchange? Would I just create mx recods that pushed the email to my domain and then have it push from there? I am a microsoft network 2003 r2, exchange 2003. If anyone could point me to some articles that would help I would greatly appreciate it. I am currently combing my admin handbook for 2003 ad.
