This is both true and not true.
In small environments it is common to see Exchange installed upon domain
controllers (especially SBS and EBS and other small-number-of-server
companies). While this is not a recommended configuration, it is supported.
In the case where Exchange is installed on a DC, that DC MUST be a GC;
further, Exchange will ONLY use the AD services of that particular server -
that is, there is no performance offloading or AD failover available.

There is a link in that article to a similar article for Exchange 2003.

Well, be aware that there are rules around what FSMO roles should coexist
with a GC - specifically the Infrastructure Master should not coexist with
the GC role on a DC, unless all DCs in your environment are GCs OR you are
in a single domain forest. See
http://www.windowsdevcenter.com/pub/a/windows/2004/06/15/fsmo.html for a
nice write-up on this.
And there is (or should be) no special action required to "alert" the
Exchange servers that a new GC exists.

-------------------------------------------------------Hi Patrick,
I also agreed with Andrew, you have to just promote one DC as GC and
exchange server will automatically discover the new GC.
