2. Though cannot change any objects, but can
- 1. view all system objects (logins, DTS etc)
You can disable the msdb guest user (EXEC msdb..sp_dropuser 'guest') to
prevent access to msdb. This will prevent viewing DTS packages. See
http://support.microsoft.com/default.aspx?scid=kb;en-us;282463.
You can 'REVOKE SELECT FROM syslogins' to prevent non privileged users from
enumerating logins via EM.
3. STOP SQL Server Agent
4. RESTART SQL SERVER!!!!
The ability to stop and start services is controlled through Windows
permissions, not SQL Server security. If the account is a member of the
Windows 'Administrators' or 'Power Users' groups, then the user can stop and
start services using any tool or command. EM will not allow non-privileged
users to stop/start services.

Hope this helps.

Hi.
When creating a SQL Server2000 login (NT Authen) with read-only rights to
user tables in a user database, this very same login can:
1. Login into EM
2. Though cannot change any objects, but can
- 1. view all system objects (logins, DTS etc)
3. STOP SQL Server Agent
4. RESTART SQL SERVER!!!!
This all seem to be traced back to the fact every login is a member of the
PUBLIC role, and the PUBLIC role allow u to do all of the above!!!
Can anyone tell me how to:
1. Prevent user (not DBA, DBO's etc) login into EM???
2. Prevent user login into QA???
Cheers!
