Need to install new Exchange Server


I have a domain controller with Windows 2012 R2 and another machine with Windows 2012 R2.  I was thinking installing exchange in DC..but not sure if it is a good idea. I prefer to leave the other machine if need it.

What you think?

Hi Hank,

I will never recommend to install Exchange in DC. You will have a lot of my experience it is a bad idea to install Exchange in DC. Before it was possible with SBS server but I see that you have the domain controller in Windows Server 2012 R2.

I have read about it is not good idea...but i want to check another opinion.

Don't. It is *barely* an opinion. It is practically settled science. More concrete than global warming. Just don't.

Running AD and Exchange on the same machine will not only cause technical issues, but it will be SLOW if you have a lot of users. It is better to separate them out for a variety of reasons like better performance from separating usage, faster reboots of the domain controller, etc.

Very interested.
It's really BAD idea installing Exchange on DC but is a very good Idea making Exchange as secondary DC.
I had this before in 10+ clients and this is my primary work configuration for over 4 years.
I've never get any issues with that configuration no matter what people are saying.
