Setting Up Multi-Server Administration---SQL Server Account

Question

I am trying to set up Multi Server Administration so that I can easily update multiple instances of the same database across our network with ease. Where I am getting lost is how to set up the SQL SERVER AGENT service on the target machines.

Right now the SQL SERVER AGENT services on the machines are set to log on as NTSERVICE\SQL SERVER AGENT.

My SQL Server Agent process is set to log in as LocalSystem

My overall goal here is to figure out why I can't set any target servers from my machine, as I always run into the following error:

When looking at the log on my machine I see the following error when trying to enlist the target machine:

Login failed. The login is from an untrusted domain and cannot be used with Integrated authentication.

Answer 1

One weakness of MSX is that target servers uses Windows authentication and you can't change that.

I.e., your target Agent need a domain account as a service account and that account need to exist as a Windows login on the master SQL Server (and also be a user in the msdb database there and a member of the TargetServersRole).
