Hi @EPSrookie
The error you are getting from the repadmin is because you have entered the server and DN in the wrong format, I'm not sure which object you are trying to get the metadata for but this is the command to get the metadata for the domain controllers OU, w2k19 is the name of the DC.
I would suggest that you run dcdiag /v /f on each domain controllers and resolve any errors.
Also have a look at the Lingering Object Liquidator tool which might help you clean up your lingering objects.
