I have recently had to completely re-install my DC which acts as DNS, DHCP, AD and File server. Before this re-installation, it also hosted exchange and IIS. Now I have outsourced the email and website to O365.
O365 is configured with the domain: example1.org.uk.
Is it okay to configure my DC FQDN as example1.org.uk or should I name it something different, such as example1.com or example2.org.uk etc?
Thanks in advance!
