Hi,
Using the setup wizard and configure the SQL Server Databse Engine to use domain account and cheking the checkbox: "Grant Perform Volume Maintenance Task to SQL Server Database Engine Service"
ConfigurationFile.ini:
....
SQLSVCACCOUNT="<domain>\<user>"
; Set to "True" to enable instant file initialization for SQL Server service. If enabled, Setup will grant Perform Volume Maintenance Task privilege to the Database Engine Service SID. This may lead to information disclosure as it could allow deleted
content to be accessed by an unauthorized principal.
...
The Setup does not grant the privilege to the configured domain account, instead NT SERVICE\MSSQLSERVER is granted the permission.
Regards,
Brynjar
