Today while installing a new Exchange Server to create a DAG (Database Availability Group) I ran into the following error below:
First thing that I checked was that the domain\Exchange Servers was part of the following Manage Auditing and Security Log.
Computer Configuration -> Windows Settings -> Security Settings -> Local Policies -> User Rights Assignment -> Manage auditing and security log
Indeed it was, so all I did was block inheritance on the OU and then tried running the setup again and it worked without a problem. Once done I removed the block and set everything back to what it was. Alternatively you can move the machine to an OU where inheritance is blocked on the policies.
Hope it helps.
