This article introduces SQL SERVER 2005 windows authentication mode to sql server authentication and how to solve the connection display TCP/IP problem, the content is very detailed, interested friends can refer to, hope to be helpful to you.

Windows authentication mode was selected when installing Microsoft SQL Server 2005. When connecting to the server from Microsoft SQL Server Management Studio, the sa user cannot log in with an error:

Microsoft SQL Server Error 18452: Login failed... Not associated with a trusted SQL server connection

Enter Microsoft SQL Server Management Studio, right-click the server name, select "Properties", and select "Security" to make the following changes.

If you fill in the IP address instead of the machine name at the server name, the connection always indicates failure

Solution: open "start-all programs-Microsoft SQL Server 2005-configuration tools-SQL Server configuration Manager", in the pop-up form, find "SQL Server 2005 Network configuration", enable "Named Pipes" and "TCP/IP" under "MSSQLSERVER Protocol", and then restart SQL Server.

If the default administrator user of the vista system cannot restart SQL Server, the SQL Server peripheral application configuration is required to add the administrator user as a privileged user.

So much for the conversion of SQL SERVER 2005 windows authentication mode to sql server authentication and how to solve the problem of connection display TCP/IP. I hope the above content can be helpful to you and learn more. If you think the article is good, you can share it for more people to see.
