function Update-DbaServiceAccount { <# .SYNOPSIS Changes service account (or just its password) of the SQL Server service. .DESCRIPTION Reconfigure the service account or update the password of the specified SQL Server service. The service will be restarted in the event of changing the account. .PARAMETER ComputerName The target SQL Server instance or instances. .PARAMETER Credential Windows Credential with permission to log on to the server running the SQL instance .PARAMETER InputObject A collection of services. Basically, any object that has ComputerName and ServiceName properties. Can be piped from Get-DbaService. .PARAMETER ServiceName A name of the service on which the action is performed. E.g. MSSQLSERVER or SqlAgent$INSTANCENAME .PARAMETER ServiceCredential Windows Credential object under which the service will be setup to run. Cannot be used with -Username. For local service accounts use one of the following usernames with empty password: LOCALSERVICE NETWORKSERVICE LOCALSYSTEM .PARAMETER PreviousPassword An old password of the service account. Optional when run under local admin privileges. .PARAMETER NewPassword New password of the service account. The function will ask for a password if not specified. MSAs and local system accounts will ignore the password. .PARAMETER Username Username of the service account. Cannot be used with -ServiceCredential. For local service accounts use one of the following usernames omitting the -Password parameter: LOCALSERVICE NETWORKSERVICE LOCALSYSTEM .PARAMETER WhatIf Shows what would happen if the command were to run. No actions are actually performed. .PARAMETER Confirm Prompts you for confirmation before executing any changing operations within the command. .PARAMETER EnableException By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message. This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting. Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch. .NOTES Tags: Service, SqlServer, Instance, Connect Author: Kirill Kravtsov (@nvarscar) Website: https://dbatools.io Copyright: (c) 2018 by dbatools, licensed under MIT License: MIT https://opensource.org/licenses/MIT Requires Local Admin rights on destination computer(s). .EXAMPLE PS C:\> $NewPassword = ConvertTo-SecureString 'Qwerty1234' -AsPlainText -Force Update-DbaServiceAccount -ComputerName sql1 -ServiceName 'MSSQL$MYINSTANCE' -Password $NewPassword Changes the current service account's password of the service MSSQL$MYINSTANCE to 'Qwerty1234' .EXAMPLE PS C:\> $cred = Get-Credential PS C:\> Get-DbaService sql1 -Type Engine,Agent -Instance MYINSTANCE | Update-DbaServiceAccount -ServiceCredential $cred Requests credentials from the user and configures them as a service account for the SQL Server engine and agent services of the instance sql1\MYINSTANCE .EXAMPLE PS C:\> Update-DbaServiceAccount -ComputerName sql1,sql2 -ServiceName 'MSSQLSERVER','SQLSERVERAGENT' -Username NETWORKSERVICE Configures SQL Server engine and agent services on the machines sql1 and sql2 to run under Network Service system user. .EXAMPLE PS C:\> Get-DbaService sql1 -Type Engine -Instance MSSQLSERVER | Update-DbaServiceAccount -Username 'MyDomain\sqluser1' Configures SQL Server engine service on the machine sql1 to run under MyDomain\sqluser1.
