Who has CONTROL SERVER in SQL 2005?

have you tried sys.database_permissions
but presumably you'd also need to know if the id had dbo/sysadmin ... rights as  well..

sorry misread that as just CONTROL

sys.database_permissions appears to just be database level permissions.  I also checked sys.server_permissions, but I didn't see "CONTROL SERVER".

But I see from the following microsoft page that the "CONTROL SERVER" permission would be shown in the sys.server_permissions table:
 http://msdn2.microsoft.com/en-us/library/ms186260.aspx

Here's how I got my answer:

select b.name, a.permission_name from sys.server_permissions a, sys.server_principals b
where a.grantee_principal_id = b.principal_id
and permission_name = 'CONTROL SERVER'
