Hello jarves123, I have seen some issues when customers configure there NS servers.  It is best to follow the configuration best practices that we have for configuring smartconnect.  The links are to customer facing documents so as long as you are logged into your EMC account you should be able to access the links.  Here is an additional link as well. [URL]
I have a question. Can we add the ns servers in the NameServers tab along with the Windows DNS servers? [IMAGE]   Or do we really need to create a child zone for delegation?
