It is technically possible, but installing exchange on a domain controller is *strongly* discouraged. It really should not be done. Use a second server or virtualize.

Yes Cliff is correct,
don't mix your AD and exchange, even don't virtualize the server which you installed AD. Even it is ok if you can go with low conf. servers.

This is not a supported method by Microsoft.

Are your AD admin tools letting you down?

Managing Active Directory can get complicated.  Often, the native tools for managing AD are just not up to the task.  The largest Active Directory installations in the world have relied on one tool to manage their day-to-day administration tasks: Hyena. Start your trial today.

It *IS* a supported method but it is NOT a recommended method.

What about AD in a Windows Server 2008 standard and Exchange and DNS Windows Server 2008 R2?

AD and DNS on Server 2008 and Exchange on its own on Server 2008 R2 would be the ideal way to go.

even don't virtualize the server which you installed AD.
Sorry but I don't agree with this comment from Praveen Kumar Bonala. With the improvements in virtualization this isn't such a big problem as it once was a few years ago.

I don't think you can separate AD and DNS on TWO servers
It should be on same server only

For Exchange other experts already provided appropriate answers

You absolutely can.  You don't even need to use Windows DNS.  HOWEVER, in ALMOST all cases, you should.  (DNS requires the ability to perform Dynamic Updates - there are other DNS servers (on *nix platforms) that WOULD be perfectly suitable.

That said, and to be clear, if you don't have an extremely good and specific reason not to, you SHOULD be running DNS and AD on the same server.  NOT Exchange though.  That should be on a different server, even though it is technically supported.

Just to chime in, also agreeing with Lee as you can have DNS separate from a domain controller. however you lose all redundancy when you are not using AD with DNS. Also Backups now become more complex because you need to ensure 2 different backups are successful etc.

So yes i can be done, but definitely not recommend.
