"..Unnatural work produces too much stress.."

An error occurred during discovery of the database availability group topology. Error: An error occurred while attempting a cluster operation. Error: Cluster API “AddClusterNode() (MaxPercentage=12) failed with 0×80070005. Error: Access is denied.”

If the witness server you specify isn’t an Exchange 2010 server, you must add the Exchange Trusted Subsystem universal security group to the local Administrators group on the witness server. These security permissions are necessary to ensure that Exchange can create a directory and share on the witness server as needed. If the proper permissions aren’t configured, the following error is returned:
Error: An error occurred during discovery of the database availability group topology. Error: An error occurred while attempting a cluster operation. Error: Cluster API “AddClusterNode() (MaxPercentage=12) failed with 0×80070005. Error: Access is denied.”

If you specify a witness server, you must use either a host name or a fully-qualified domain name (FQDN). Using an IP address or a wildcard name isn’t supported. In addition, the witness server cannot be a member of the DAG.
