We have a 2003 Domain Controller and want to know if you can have a 2008 Domain Controller in the same domain?

Yes - but you will need to run ADPREP (ADPREP32) to update the 2003 schema, see http://www.petri.co.il/prepare-for-server-2008-r2-domain-controller.htm

I am running a mixed environment while working towards a full 2008 environment.  before being able to add a 2008 DC you need to do a schema update.  At which point you can still continue to add 2003 and 2008 domain controllers until you change the domain to be a 2008 functional level.

Hi,

Yes this is no problem. Before you are going to promote the windows 2008 R2 server you have to prepare your active directory.

Here http://sharepointgeorge.com/2009/introducing-windows-2008-r2-domain-controller/ is a good guide how to do this.

Note, after introducing, make sure you do not upgrade your forest / domain functional level to a higher level then window 2003, otherwise you will have problems with your 2003 domain controller.
Note if you run adprep on a 2008r2 server they supply both a 32bit and 64bit version on the r2 64bit cd/image.  This tripped me up for a while as this changed from 2008 which you had to use the adprep from the proper cd.
