I am replacing a 2003 domain controller with a new 2008 R2 domain controller at one of our sites. We already have 2008 domain controllers at other sites. I dcpromo the new domain controller, and seems to have replicated fine from the old 2003DC at the same site, however when I go into the DNS, it only shows a link with the 2003DC. Will this automatically update with a link to a DC at our main site? I see that the old 2003 DC has an automatically generated connection that goes to our main site domain controller. If I DCpromo out the old 2003DC at this site, will the 2008DC automatically generate a connection back to the main site to the other DC?
