I am running Windows server 2019 standard with desktop experience. I have the server setup as a active directory domain controller. I installed OM-SrvAdmin-Dell-Web-WINX64-9.3.0-3465_A00 and it installs without any issues. I cannot get any version of username/password to work. Tried:
user password

Domain\user password

user@domain password.

I even installed the active directory extensions and still cannot login. Are there any log files that I can check to see what the issue is? 

I have read countless articles about how it should work with one of those username/password combinations, but there must be something else going on.

Can I run it on a domain controller? 

I have it running as a hyper-v server. I could spin up another image and make that a domain controller and demote this host server.

Thanks,

Brian
