Select Windows Authentication
from Authentication dropdownlist and click Connect
. Now you should be connected to the server.
During installation it must have asked you for authentication type for login such as Windows Authentication
, which is default and SQL Server Authentication
If you have missed this step, nothing to worry , go through the following link
Unable to login to SQL Server + SQL Server Authentication + Error: 18456
Hope that helps !
