Everything went fine until I decommissioned the old server. It went to workgroup and I changed its name and IP. I tried to change the IP on the new server to the previous one and it started to act slow then crashed. I noticed that the Ethernet connection says private instead of domain also. I figured that I would change the IP back, so I did. Now Netlogon will not start and AD is not working. (It can't find the Domain) I have alot of questions now..............Any help?
Try to restart Network Location Awareness Service on your 2019 and then run dcdiag /fix. After that reboot the server.
I tried that and I am still at the same spot. I just found out that while I was getting on site, someone tried to change the name of the server, so it probably doesn't have anything to do with the IP change. DNS shows green but when I try to run dcdiag /fix the first testing server is the former name. I have several backups I may just go through the guide again. I wasn't really trying to memorize the guide though. :) Please excuse my typing, I have been up too many hours.
Can you contact 'someone' and ask how they renamed it?
