error parsing input - invalid syntax

Question

Hi,

I just decommissioned a physical backup domain controller. I spun up a new backup domain controller on Hyper-V and promoted it to a secondary or should I say third domain controller. I went ahead and already added the AD + DNS roles to it and verified it can replicate from primary to new BDC and vice versa.

Below are the following steps I have taken so far:

DC.promo.exe
Removed AD + DNS roles
Removed FQDN for BDC.contoso.sales. Now it’s just named BDC
after doing this, I noticed in AD that under the domain controllers, the old BDC server is still showing up.

after doing some research, it says that I have to run NTDSUTIL to clean up the old remnants of the old BDC server.

However, when doing this, I can only get up to the point of where it says server connections. When I try entering BDC or BDC.contoso.sales I get the following error message.

error parsing input - invalid syntax

I did do a ping to BDC and see that it can resolve the name with its' IP address.

Can anyone tell me what I'm doing wrong ,and how to get the NTDS Utill to run properly?

Hi,

Did you try to Clean up server metadata by using GUI tools:
https://learn.microsoft.com/en-us/previous-versions/windows/it-pro/windows-server-2008-R2-and-2008/cc816907(v=ws.10)?redirectedfrom=MSDN
Can it cleanup the old DC clearly？

Best Regards,
