Hi,
We have a green field AD forest deployment in which we have AD, DHCP, SQL cluster, PKI, System Center 2016 and Symantec Endpoint Protection. All services are almost deployed. Suddenly we are asked to change the domain name from xxx.yyy to zzz.www (total domain fqdn change). Now is this is something supported? what about the SIDs for the accounts used as services in various products installed? Note that the domain and forest functional level is Windows Server 2012 R2.
