repadmin removelingeringobjects

Hello,

I have a single DC environment (that had previously demoted DCs) I've tried searching for tutorials on how to show lingering objects in AD using repadmin.

Here is the command that I see:

repadmin /removelingeringobjects <Dest_DSA_LIST> <Source DSA GUID> <NC> [/ADVISORY_MODE]

I keep coming up with a help file like thing when trying to run it. 

Since there is only one DC at this point, I am using it like this:

repadmin /removelingeringobjects  dcname   dc_guid (found by repadmin /showrep or NTDS settings) and directory path (dc=domain,dc=tld) /advisory_mode

I keep getting errors. I am not certain if it can be run against itself in a single dc environment. If anyone can provide help. Please let me know

Thanks
