Ok, please pardon me for my obvious n00b question.

I'm pretty much certain that we will be switching our email over too Open-Xchange from our existing M$ Exchange server. Are network is only about 300 users strong. None the less, I would rather not cripple it through my own ignorance of Linux and Open-Xchange.

With that said, during the installation (Appliance Ver) process it forces me to use Domain Controller Master which I understand is required for this particular version. Now, coming from a Windows domain world, little bells and red flags fill my brain. Am I going to effect my Windows Domain in anyway?

Further on in the installation, it wants to know what my domain is. Do I use my Windows domain or does this need to be something completely different.

Thanks for the Help
Eric
