Your login failed. Please contact your system administrator

When logging into SmartConnect, receiving an error that says, “Your login failed. Please contact your system administrator”.
This means your Windows login does not have permissions to login to SmartConnect. Run the following query in SQL management studio
select * from SmartConnect.[dbo].[User] where IsAdmin=1
This will give you a list of all the administrators in SmartConnect. You need to have someone who is listed there login to your machine and launch SmartConnect. Then go to the Setup tab and click on the security button. Have them add your Windows login in the SmartConnect security window and you will be able to login to SmartConnect using your account.
