2.Log onto MS SQL Server management studio using Windows Authentication.
3.Right click on the SQL server name (eg:VPS123123) >> Properties.
4.Select the Security tab from left >> Server Authentication >> Select "SQL Server and Windows Authentication Mode" , Click OK.
4. Expand Security pane >> Logins >> Right click on sa user >> Properties.
5. Select the status >> Settings >> Login >> Select "Enable" >> Click Ok.
6.Restart the SQL server services and try to login as the user "sa" .
Thank you,
