>According to the IT customer guy (who is not a DBA; they don't have a DBA) the SQL is installed on the same box where I am connecting. He also cannot see the name of the server when going to SSMS. But when I go to the Programs -> SQL -> Configurations Manager I see that SQL Server is running. So I presume that I am connected to the right box. There are two things not running on in the Configuration Manager:
>SQL Server Browser and SQL Server Agent.

If you open SSMS on this computer, are you able to connect using (local) as Server name?
