Why one should Use SQL Server Configuration Manager to Change SQL Server Service Account or to Change Password?
Database Administrator should always use SQL Server Configuration Manager Tool to change SQL Server Service Account or to change the password for any of the SQL Server Services.
The biggest advantage is; it performs additional configurations such as setting permissions in the Windows Registry so that the new account can read the SQL Server settings immediately once it is changed using SQL Server Configuration Manager or SQL Server Management Objects (SMO) or using Window Management Instrumentation (WMI). The other advantage is it will come into effect immediately without the need to restart the SQL Server Service thereby helping you avoiding the downtime. Hence, you should always avoid the practice of changing the SQL Server Services account or changing password using SERVICES.MSC.
Managing SQL Server and Client Network Protocols
Database Administrator can use SQL Server Configuration Manager to configure server and client network protocols and also to change the connectivity options.
Supported SQL Server Network and Client Protocols
Microsoft SQL Server 2005 and higher versions support below mentioned network and client protocols.
1. Shared Memory
2. Named Pipes
Important Note: The VIA protocol is deprecated in Microsoft SQL Server 2008 and it will be removed in the future versions of Microsoft SQL Server, hence avoid using it in future development.
