Log in to management studio

Posted on 2011-02-19
Last Modified: 2012-05-11
If I log into windows as 'administrator' and then start sql server management studio using windows authentication (the username is administrator with the password blanked) then I can connect ok, update databases etc.

I've created a new login user and added it to the administrator group, but when I start sql server management studio using windows authentication (username is the new login user with the password blanked) I get a login error
"Login failed for user instance\xyzuser (Error : 18456)

Any suggestions?

Do I need to add the new user to certain groups to allow login?

Choosing Windows Authentication from setup, will create an sa account  that can be uesed from SQL Server. Initially  it is not enabled.
Later you can change to Mixed Mode Authentication. There you must first enable the account created above. Any Windows or SQL  account can be configured as system administrator.

Also check and add your domain credentials as a SQL Server login.

and in case of Vista Windows 7:  you should select Run as Administrator when running Management Studio.

In case of more admin users needing to connect you can:

1)  create a group with the logins
2) then create login for the group in SQL Server

check if the group administrators is added to the sql server logins.

if not then add it and that should fix the problem.
