@mcliviu have you ever looked at the baseline security policies for Windows?




It specifies the following should be set for Windows clients and member servers

Network access: Restrict clients allowed to make remote calls to SAM



Domain Controllers are listed as blank. Which I think is required to allow a DC to work correctly.


I thought by default the remote SAM was open to Anon access? Or is that when the domain has gone through upgrades from early versions? So if it's not open, I would have thought you already had a GPO in place that was locking it down? If you're locking it down via GPO you should be able to add the AATP account to that GPO.
