hello, we have a domain containing one DC (other DC failed) which is running server 2000, the domain functional level is 2000
the 2000 server is the last to be replaced in our domain, everythign else is using Server 2012/ 2012R2
i have two brand new 2012 servers that i want to take over the running of the domain, i have just tried to promo one of the new servers an hit an error
"Verification of replica failed. the forest functional level is Windows 2000. To install Windows Server 2012 R2 domain or domain controller, the forest functional level must be Windows Server 2003 or higher"
now, will the existing DC (W2k) upgrade the domain functional level to 2003 - if so how can i do it without effect domain services
