Hello,
I have recently installed SQL Server 2017 Enterprise Developer Edition for evaluation and am particularly interested in all aspects of security. So for the install, I have checked to install SSIS Scale Out Master and SSIS Scale Out Worker. I accepted the default virtual service accounts for these two services as well as for others (ie sql server, sql server agent). I configured SQL Server login audit events to write the Windows Event -> Application Log. I keep seeing entries like in Windows Event Viewer:
Login failed for user 'NT Service\SSISScaleOutMaster140'. Reason: Could not find a login matching the name provided. [CLIENT: <local machine>]
I then checked the Local Users & Groups on the SQL Server machine and I didn't see this account - 'NT Service\SSISScaleOutMaster140' or any other service accounts (like sql server service, agent and etc..) which I had accepted as defaults during the installation.
Questions are:
Q1 - Where do I find these virtual accounts - NT Service\*
Q2 - What's the reason for the login failure related to 'NT Service\SSISScaleOutMaster140' and how do I fix this?
Thank you
