Question may be a bit based on the earlier question i posted. Have an existing server 2003 and a Server 2008 standard, with both as domain controllers (forest and domain function levels set at server 2003 on both). Adding a server 2012 R2 standard and want to add it as a domain controller. Believe going thru the steps it will configure itself at the 2003 level automatically, and add itself as a domain controller to both.
My question is will adding this unit as a domain controler impact functionality of the network during the work day. Will it have to disconnect users in the domain while it registers or will it add itself with no impact since 2 other servers are already controller the domain. Thanks for any help you can provide.
