Hello I have a standalone Server 2019 PDC, nothing else, but I need to change the IP before adding servers and desktops. If I want to change the server IP is there anything else I need to change? Thanks Bruce

Hi,
The DC name can be changed.
For the steps ,you can refer to the following link:

Make sure all related records should be updates correctly.
For applications you should check the code where the old dc name defined and change with new name and ip address

If just changing the address then after change you can do ipconfig /flushdns, ipconfig /registerdns then restart the netlogon service. If you're also changing the subnet then recreate the revers lookup zone.

Sorry about this, can I change the name of the server?

Thanks

You can but its risky, especially with a single domain controller. The preferred and much safer method would be to stand up new one with the desired name, patch fully, join existing domain, promo it, transfer roles over, decommission demote old one.
