Okay i was doing a laboratory to see how this worked so i have this scenario A single forest and single domain test.local with a 2003 server which is the DC So i do this i configure the site and srvices i create the 2 sites site A and site B i create the subnets and assign them to the sites i run forestprep riase funtional level to 2003 on the windows 2003 to win 2003 i run domainprep So i though iwas ready i went to my new 2008 server i install the role of AD i put the DNS server pointing to the win 2003k which is a AD integrated with dns i select existing forest in a existing domain, and everything is going good.. it detect he belongs to site B cause of the site and sevivecs configuration everything is NICE and then i get this warning a delegation for this dns server cannot be created because the authorative parent zone cannot be found. To enable a realable DNS dns name resolution from the outside of the domain you should create a delegation to this dns server manually in the parent zone Is there anything im doing wrong in my laboratory? what does this mean?

I would understand if its my first forest and firts domain as its pointing to himself so he doesnt find any DNS server but i already got one running in the 2003 server thats why i dont get what it means with this message?

Hello, it sounds for me that the Windows server 2008 DC is NOT installed as additional DC in an existing domain, instead you made it a DC in a NEW forest/domain, please clarify this. If it should be an andditional DC in the existing domain you can follow: http://msmvps.com/blogs/mweber/archive/2010/02/10/upgrading-an-active-directory-domain-from-windows-server-2003-to-windows-server-2008-or-windows-server-2008-r2.aspxBest regards Meinolf Weber Disclaimer: This posting is provided "AS IS" with no warranties or guarantees , and confers no rights.

nope the windows 2008 is additional DC in a EXISTING domain Anways i jsut ignored thta and continue with the installation and its replicating with no issue but still i dont understand why i get that warning like i said i would understand if it was the first DC in a new forest and domain as there isnt any DNS server and its pointing to himself that it doesnt have any I invite you to do a fast lab with 2 virtual machines Set the first one as a DC with integrated DNS,configure all the settings on site and serveices and then install the other one as a existing domain with integrated dns and you will get that message

Hello, i assume you configred the server to use itself as DNS on the NIC and until that poinit it isn;t DNS server. make sure to use only the existing DNS server as preferred on the NIC.Best regards Meinolf Weber Disclaimer: This posting is provided "AS IS" with no warranties or guarantees , and confers no rights.

Well no When i was configuring the second server which will be my second DC on the NIC before doing Anything i put as DNS server my primary DC that was already configured as DNS. Well im just starting to learn servers and microsoft hehe since i just been looking at switches routers firewalls on my job so im new at this... and well i dont understand why i get that warning. And when i do something i try to understand what im doing not just do them and well okay its working... and leave it like that.
