Adding Devices To UCS Domain No Longer Works

Greetings,

I hope you are well. I’ve been having issues adding new computers to UCS. Adding MacOS devices show a “Node name wasn’t found” error and Windows devices show a “The user name or password is incorrect.”. In my attempts to diagnose the issue, I was reading and followed some of the steps in Samba 4 Troubleshooting article in the KB (Samba 4 Troubleshooting) and tried running this command:

samba-tool drs kcc -UAdministrator ucs.bmd.global

This was the result:

dcerpc: bind_nak reason 0 - NT_STATUS_UNSUCCESSFUL
dcerpc: bind_nak reason 0 - NT_STATUS_UNSUCCESSFUL

raise drsException(“DRS connection to %s failed: %s” % (server, e))

Can anyone point me in the right direction to fix this?

Regards,
David.
