HAve an office with a domain controller of 2003. Putting in new server with 2012 Standard. During Active Directory install, it installs DNS automatically. the new server is part of the domain but it refuses to see the 2003 server as the Domain Controller so it can be promoted. We have upgraded the functionality on the 2003 to 2013 since server 2013 will not work with anything less than 2013. Any reason why this new server will not see the domain controller even though it is part of the domain?
