I'm trying to log in to SQL Server 2008, but the installation and the log_in user were done by my friend. Now I'm to trying to open the management studio but I get the error message "login failed" although SQL Server service is running. How can I check if the user is member of Server Admin role?
Assuming you have the ability to log into the OS either remotely or locally and you have been granted elevated privileges, you have a couple of options...
- Execute T-SQL queries using SQLCMD under the SYSTEM account. You should be able to build out the T-SQL to add your account to the sysadmin fixed server role.
- Add your account to the SQL Server Database Engine service group. More information available here
