ADPrep Execution Failure
I am trying to promote a virtual machine (10.0.0.242) to a domain controller, but I keep receiving this error:
ADPrep execution failed --> Microsoft.DirectoryServices.Deployment.ADPrepLdapException: No Such Object. Server extended error: 8333. Server extended message: 0000208D: NameErr: DSID-03100245, problem 2001 (NO_OBJECT), data 0, best match of:

My current dc (10.0.0.241) is a physical server running 2016 standard. The virtual machine/server I am trying to promote is running server 2022 standard.
- Both servers can ping each other
- Both servers are on the same subnet
- Both servers have their DNS set to 10.0.0.241
- Schema is set to 88 on my current dc
- No replication errors are shown on my current dc
- I was able to promote a test physical server to a domain controller. I have cleared that server from the domain
Any help to figure out why this happening or how to fix it would be greatly appreciated. I can provide all logs, ipconfigs, replsum, etc.. to whoever wants to help.
