Revoke Connect Guest User

Feb 7, 2008

I've used the following:
EXEC sp_MSforeachdb 'USE [?];
REVOKE CONNECT FROM GUEST;'
GO

And this is what I get:
Msg 15182, Level 16, State 1, Line 2
Cannot disable access to the guest user in master or tempdb.
Msg 15182, Level 16, State 1, Line 2
Cannot disable access to the guest user in master or tempdb.
Msg 15151, Level 16, State 1, Line 2
Cannot find the user 'GUEST', because it does not exist or you do not have permission.
Msg 15151, Level 16, State 1, Line 2
Cannot find the user 'GUEST', because it does not exist or you do not have permission.
Msg 15151, Level 16, State 1, Line 2
Cannot find the user 'GUEST', because it does not exist or you do not have permission.

When I do this:
EXEC sp_MSforeachdb 'USE [?];
SELECT ''[?]'' AS DBName,* FROM sysusers;'
GO

The guest sid for all tables shows 0x00, is this the reason I get above errors?

Schema Revoke SELECT Permission

Sep 15, 2006

HI, I have set up a database with 5 users, USER1 has default schema USER1, USER2 has default schema USER2 and so on. My problem is that I want to revoke select permission on schema USER1 to user USER2. I issued the following TSQL in SSMS:

REVOKE SELECT ON SCHEMA::USER1 to USER2

Even though I did that, I can still log on as USER2 and be able to issue SELECT statements on USER1 schema tables. The only way I can do to avoid the SELECT on USER1 schema is to DENY select on USER1 schema. Is it normal?

Thank you for your help,

Ccote

DENY Or REVOKE Rights To PUBLIC And GUEST

May 14, 2008

Hi Guys,
We are using MS SQL 2005. I am ask to remove the PUBLIC rights to the objects listed in the following query in the master DB:

SELECT sysusers.name, sysobjects.name,sysprotects.action FROM sysobjects, sysusers, sysprotects WHERE sysobjects.id = sysprotects.id AND sysprotects.uid = sysusers.uid AND sysprotects.protecttype = 205


I keep having the "Cannot find the object [Objectname], because it does not exists or you do not have permission."

How do I create a query to remove the PUBLIC rights at a single run. (There are total of 1660 items, please dun ask me to write the DENY or REVOKE statement 1660 time )

How do I DENY the rights for objects starting with the prefix "dm_" or items like "TABLE PRIVILEGES"
Thanks guys Any help on this is greatly appreciated.

Trouble With Cursor Designed To Revoke Object Access.

May 30, 2008

Hi everyone. I am having difficulties with a cursor that I am trying to write. The purpose of the cursor is to loop through all tables in a selected Database and revoke "Select" access to that table for the indicated role (RoleToRevoke). I am getting the error on the @name variable within the REVOKE statement. I have placed a comment indicating where I am getting the error. Is there a way to have sql server interpret this @name variable within the REVOKE statement? Thanks for your help.




Code Snippet

USE [Database_Name];

Declare cursorExample Cursor for
Select TABLE_NAME
from information_schema.tables
Where TABLE_TYPE='Base Table'
and TABLE_SCHEMA='dbo'

Declare @name as varchar(255)
Declare @ErrorSave as int
Declare @ErrorCount as int

Open cursorExample

Fetch Next from cursorExample into @name


SET @ErrorSave = 0
SET @ErrorCount = 0




Begin Tran

While @@Fetch_Status=0

Begin

--Getting Error on Line below on @name
REVOKE SELECT ON OBJECT::@name FROM RoletoRevoke;

IF (@@ERROR <> 0)

BEGIN

Print 'Error Revoking Access to Table: ' + CAST(@name AS varchar(75))
SELECT @ErrorCount = @ErrorCount + 1
END
IF (@@ERROR = 0)

BEGIN

Print 'Successful Revoking Select Rights on Table: ' + CAST(@name AS varchar(75))








SELECT @ErrorSave = @ErrorSave + 1
END
Fetch Next from cursorExample into @name


End

IF @ErrorCount = 0

BEGIN

COMMIT TRAN
PRINT 'COMMITTED TRANSACTION'
PRINT 'Total Tables Affected:' + CAST(@ErrorSave AS varchar(75))
END
ELSE

BEGIN

ROLLBACK TRAN
PRINT 'ROLLED BACK TRANSACTION'
END

Close cursorExample
Deallocate cursorExample
GO

Apr 17, 2015
