I'm currently using 2 2003 servers, but looking at upgrading to EBS 2008 Standard on 3 servers, but I am trying to find clarification on a few points.In the FAQs and other information I read that the EBS domain has to be the root of the forsest and there cannot be any child domains. The Messaging and Management servers are the domain controllers for the domainI have read on various sites that you can add EBS to an existing domain, does this mean there can be additional domain controllers?I have also read that you can create child domains, but not with the EBS servers. You can also keep your child domains if you migrate to EBS.Would it be best to create the domain and the child domain and then install EBS?You cannot create child domains, but what about additional trees in the forest?I cannot find any definite information on this and I have a requirement for multiple domains within our forestThanks in advance
