We have a Server 2003 R2 domain controller at 2003 Functional Level - company-name.local
Whilst we hold out for our virtualisation project to kick in, I have been unable to upgrade these servers to 2008. We have an Exchange 2007 server within the top level domain, running or Server 2003 R2.
I have had to purchase a new DC for a new company acquisition to provide them with an AD infrastructure, but I am only able to install it will 2008 R2, it is configured as a subdomain - micro.company-name.local, it is at the 2003 Functional Level.
How can I tie Exchange 2007 into this DC so I can add a mailbox to a user in the subdomain?
I have seen on ome sites that I should domainprep the subdomain DC using the Exchange disc, however, I an unable to locate this on the downloaded ISO I have.
Could anyone advise on how to proceed?
Thanks in advance.
