Windows 2008 read only domain controllers and Exchange

I was reading some interesting threads recently on the use of Windows Server 2008 read-only domain controllers. Basically, Exchange does NOT make use of these even as global catalog servers (I hope that the Exchange team will address this for E2K7). So, every physical site that you have Exchange Server 2007, you should have read/write domain controllers.

Also, Exchange 2000 CANNOT detect what a "read only" domain controller actually is. So it will pick a read-only domain controller and then not be able to write to it. I did not get a confirmation tht E2K3 is this way also, but I'm guessing that it is.

So, read-only domain controllers are a good idea, but an idea that has not quite matured for Exchange.
