    Hi @Eudias Kifem

    Yes , you can use the same service account to configure multiple instance and SQl servers.

    A service account can be used to configure one or multiple SQL server without any issue. In the other hand I recommend you to use GSMA to avoid use a standard user account as service account with password nerver expired.

    Yes, you can do that. The main consideration is security, as the instances can access each other's data folders. One of my clients has it set up this way, but it is a dev shop, and all the instances are test/dev servers, not production.

    Hi @Eudias Kifem ,

    Yes, you can create a domain user account and use it as a logon account for multiple servers.

    By using a single service account, you can simplify the management of service accounts. You can update the password or make any changes in the service account in a centralized location.

    However, there are some possible effects of using a single service account across multiple servers. If the service account is compromised, it can impact all the servers where it is used. Therefore, you need to ensure that the service account is adequately secured with strong passwords and proper access controls.

    Best regards,
