Debugger requires access to the database in order to run.

If a user is not an administrator of the remote server machine, security configuration is required for the COM+ Security Helper application. All the users using debugger must be part of Secure Users role of Security Helper on the database server. To do this, add all the users to the Debugger Users group. This setting is required when the database server is installed in a separate or in the same remote machine with developer. Users can be added to COM+ roles using the Component Services MMC snap-in.
