I am trying to create child domain under a child domain. when I am trying to promote server as dc it is coming up as a invalid credentials. But when I am choosing tree sub domain option same credentials are working. I am using credentials of root domain. I am able to successfully create tree domain and under that a child domain. But I am having this problem when I trying to create a child domain under a child domain My network design is Andrew.com > Development.andrew.com (Child domain)>hardware.development.andrew.com(sub - sub domain this is where I am having trouble)
other side of Network is ( which I have successfully created ) Andrew.com (root) > management.com (tree domain) under that sales.management.com (child domain) I have successfully created that.
