Hello,
I am using sql server 7.0, I want to deny permission to certain extended procedures in the master database to all the dbowners of other databases. Please tell me the syntax of the command with example.
koolnyzeMake sure the dbo accounts don't have explicit access to your master database (the dbo in master is not necessarily the same as the dbo in the other databases). Then deny permission to the guest user role in master for whatever procedures you want to disallow.
Since you are making a change in your master database, be sure to back it up!
blindman|||Hi,
I want to deny the permission to dbowners for getting the directory list when they click on the backup destination for taking backups. I have denied execute pemission to guest and public for xp_availablemedia but still the dbowners are able to get the directory list. Can you please suggest how to achieve this?
Koolnyze|||Microsoft's support webset (http://support.microsoft.com/default.aspx?scid=kb;en-us;323249) had this to say:
"Only members of the SQL Server system administrators role (sysadmin) can view the directory structure and select local backup files. "
Try going into the SQL Server Security/Logins folder in Enterprise Manager. Right click on the login, select Properties, and go to the Server Roles tab to make sure that the login is not a member of the system administrators server role.
I didn't try this, so let me know if it works!
blindman|||"Try going into the SQL Server Security/Logins folder in Enterprise Manager. Right click on the login, select Properties, and go to the Server Roles tab to make sure that the login is not a member of the system administrators server role."
I checked it and the login does not have any role selected. The login has been made dbowner of one database only and cannot access any other database. Still the login is able to browse the directory tree. Any other seggestions.
koolnyze|||Jeez, I'm running out of ideas.
What about looking at the server roles themselves (System Administrators and maybe Disk Administrators) to see who IS a member? Perhaps your users have administrative access through their network login account?
Sorry I can't be of more help, but this is getting into an area where I have less expertise. A network administrator might be able to help you out.
blindman|||I have thoroughly checked but everything seems fine. It seems that something else also needs to be done before the permission to deny the view of directory tree will be effected.
Thanks for your help
koolnyze|||Hi,
Only denying permission to xp_availablemedia doesn't work. When I denied permission to xp_fixeddrives also, it started working.

Deny Create Database
User is an NT Administrator and has been made a member of Server Role sys
admin.
I'm not in the master database in query analyzer.
When I do this:
Deny Create Database
To User
I get the following message:
CREATE DATABASE PERMISSION CAN ONLY BE GRANTED IN THE MASTER DATABASE
How do I alter the SQL statement to refer to the master database?
Thanks for any help.Run:
use master
before you run the DENY.

not be the best place to do this. I could do it from a test web page but f
amiliarizing myself with Analyzer environment.
In a web environment, I know I would have to connect to the master database
to issue this command.
However, is there an 'automated' way to switch to that database in the Query
Analyzer so that I can put the code
in the same test file rather than having to run another instance of the Anal
yzer just for that? I would rather comment out a few lines that I am not te
sting at that moment rather than switch back and forth from instance to inst
ance.
Is there a command that I can put in the body of the analyzer sql script to
switch? Sorry. Kind of new at this. All of the lines in this test file do
n't have to be run on Master anyway since they are adding users to specific
databases or they are addin
g server roles which can be added from anywhere, so if I used a separate tes
t file, it would have only these two lines in it anyway.
So is there a command to switch databases that I can place in the Analyzer s
cript? In the meantime, I'll go with your answer, and thanks very much for
your prior reply.|||If you are using Query Analyzer to run a script, then the only way to
guarantee that you are in a particular database is to issue a USE command.
So, if you are running a script from within QA, and you want to be sure you
are in master, then ensure you have the following:
use master
go
-- do something
I'm not sure I understand what the issue is. You don't need separate
instances of QA or anything like that.

Thanks for the use Master go.
I'm sure it will work, and I appreciate it.
Scott|||Works great, but one thing I noticed:
Even though the commands take fine and the syspermission table record cou
nt changes as you would expect (master file), the command will not turn off
create database for a user in the sysadmin role or for a user who is not in
the sysadmin role but who i
s in the db_creator role.
So it doesn't seem to work at all. I know for a db_owner (non-sysadmin) you
have to turn on database creation after the fact, not turn it off, as I am
testing, so it does not apply in that instance.
So I'm trying to find a combination where Deny Create Database actually work
s where it would make sense. It makes sense that you might want to turn it
off for an administrator. Can't get it to work.|||Alternatively, you can send the default database to master.

can create a database. If you want to ensure they can't do it - keep them
out. A sysadmin role member can do anything, so a DENY isn't going to work
here. It's best to look at what they really need and give them only those
permissions or roles. That way, you won't need to use DENY.
