Guest Id In Tempdb Disappeared.
Feb 28, 2001Hi All,
I encountered a bizzard situation. The guest id in tempdb disappeared after I rebooted (shutdown and startup) my server. That caused errors in application whenever a stored proc needs to create a temporary table.
Has anyone seen this happened before? Any idea on why or how it happened?
Thanks in advance.

USE <Database Name>

REVOKE CONNECT FROM GUEST

Jul 20, 2005Nel database "master" ho mappato, per errore, l'utente "guest" su unutente sql "XXX" creato in SQLServer.Questo tipo di impostazione non permette più di aver accesso conl'utente anonimo "guest" (mappato su null) al db (con autorizzazionilimitate al ruolo public).Ho provato sia da EM che con le varie SP a rimuovere l'utente, amapparlo su un'altro utente, ... ma non sono riuscito a ripristinarela situazione di partenza.Mi servirebbe una idea per non dover effettuare il backup di tutti idb, disinstallare SQLServer, reinstallare SQLServer e fare il restoredi tutti i db (soluzione possibile ma che tengo come ultimaspiaggia!!).Grazie

Sep 24, 2015I've read a bunch of articles saying you should always remove the guest user from the user databases and model. It seems to me that if a user only has public access then the user can't do anything on the database. If the guest user only has public access to a user database how is it a security threat? I must be missing something.

Sep 18, 2006Hi all.
I don't know if this is the right forum to post this question, but here it goes.
We have restored into sql 2005 the database backups made in sql 2000. We connect with trusted connection and application roles, and when trying to execute a transaction to another database (with the guest user), we get a permission error.
Does anyone know if, apart from restoring the databases, we should do something else to get the guest user working the same way as with sql 2000 in the restored databases?
Thanks in advance for your help.

TempDB And User Permissions
Mar 3, 2000I have a user account that needs CREATE TABLE permission in tempdb. I know how to do this using the GUI

The problem is that this reverts whenever the DB server is restarted. I need to figure out
how to keep it from reverting, or it needs to be set in some sort of startup script.
Any help would be greatly appreciated.

SQL Server 2000 TempDB User Losing Permissions
Jan 15, 2007I am supporting a system that needs to allow users to have access to TempDB.
I set these users up using the GUI, but whenever the server is restarted, these users permissions are wiped out and the db_owner permission is lost and I have to manually go in and apply the permissons for the database to work again, it happens on most reboots but not all.
Is there anyway to keep these users permissions when the server is rebooted?
Your help is most appriciated.
P.S Could I create a stored procedure that when ever the Server is rebooted the procedure would recreate these permissions?
If I need to do this how would I go about doing this?
TempDb Drops User Account On Server Restart?
Sep 11, 2007Please forgive my ignorance, I am by no means a SQL Expert, but have encountered a strange issue.
I have 6 SQL Servers, Primarily SQL 2005 (one older SQL 2000) all loaded on Windows Server 2003 SP1.
We use the servers for a proprietary database that we created which is the backend to a software package we sell.
The issue I have is: We have added a Security account to the servers, and in one case we have granted rights for this account to the TempDB system database. However, whenever we restart this server SQL drops this user account, thus severing connectivity for the app that is relying on that account.
I have set the account as DB-Owner etc, but nothing sems to keep it on re-start.
Any input would be greatly appreciated.
Guest Access?
Oct 25, 1999If our SQL Server is not part of a domain, can "Guest" users still connect to the SQL server?
What we are experiencing is -- when a drive is mapped to the server connectivity is fine.
But, without the drive mapping, the SQL connections cannot be made.
Thoughts, Ideas,
(hopefully without adding unique logins for each user at the server)

We're running a .Net web application with a SQL Server 2000 backend, and we get the error intermittently. Restarting the SQL Server service seems to fix it, as it causes tempdb to be rebuilt, but this isn't a long term solution. Any direction or hints would be greatly appreciated. Thanks!

Login Failure For Guest
May 11, 2004I would like a guest to view some items on the application.
And I recently intalled SQL Server 2000 on my machine. Will integrate Access when ready.
I can access or simply read data from a db if I specify User ID and Password.
Such as....
Dim nwindConn As SqlConnection = New SqlConnection("Data Source=localhost;User Id=sa;Password=xxxxx;Initial Catalog=Northwind;")
Yes, testing first, then adjusting all my code for the SQL instead of Access.
If I leave the id and pw out, it won't read - login failure.
I have read so much on authentication and some posts here, even the one on login failure, but that didn't help.
Keep in mind, just installed, only users are the default ones by the installation.
What setting in the SQL Server is there, and I have looked, that if it's a guest, no id or pw, allow read only to items such as datagrids which only read from tables?
Thanks all,

Guest Account Issue
Apr 15, 2008Hi,
I have some questions regarding guest acct. I am using some database security scanning software (again) and it says that guest acct should be dropped from these databases, msdb, pubs, Northwind.
Can i safely say that i can drop the guest acct in pubs and Northwind without any issue?
For msdb, will there be any concerns? How can i verify?
If i just revoke the public permission on guest, is it the same as dropping the user?
Lastly, I see that in all databases, the guest acct exists, but some are of permit and some are of via group membership for the database access column. What is the difference?
Thanks guys. appreciate your help. Audit deadline coming up.. i still have about 20 more audit pts to go... :)

Master Db - Minimum Permissions For Guest
Jan 7, 2008
Hi All:
I hope I'm in the correct forum for this question. If I'm not, forgive me and point me in the proper direction.
I have SQL Server 2000 databases that I am trying to secure. To that end I've deleted the guest account from all but the master and tempdb databases.
Within the master db I've denied access of any "flavor" to all objects but spt_values, syscharsets, sp_MSSQLDMO80_version, and sp_MSdbuserpriv (only because I've discovered they are necessary).
Can anyone tell me where I might find the absolute minimum permissions configuration for the guest account in master?
I have no third party vendor software accessing my SQL Server 2000 databases. The thought of
Demographics:
SQL Server 2000 sp4 running on Windows 2003 Server with the current service packs.
Any help is greatly appreciated.

Guest Account Enabled Via Group Membership

I have a situation (on SQL Server 2000 SP3a) where the guest account appears in the list of database users despite the account being removed via sp_dropuser.
The guest account appears in the list of users with Database Access set as 'Via Group Membership'
Once in this state it cannot be removed as sp_drop user will now report:
Server: Msg 15008, Level 16, State 1, Procedure sp_revokedbaccess, Line 36
User 'guest' does not exist in the current database.
My conerns are:
(a) Does this imply any security risks ?
(b) How can I remove all reference to the guest account?
Any ideas or suggestions would be appreciated

Public Role And Guest Security Concern In SQL 2000 SP4
Sep 8, 2006Hi all,
I have setup a new SQL 2000 SP4 and internal auditor query about revoke permission from Public role and remove guest from all databases.
1. Can I revoke all default permissions (select on system tables in all DBs) from "Public" role? I am concern any error after such action.
2. I found that guest account in DB -- master, tempdb and msdb. According to Microsoft documents. The account should not remove and can't from master and tempdb. How about msdb?
Thanks,

Guest Principal Assigned To Datareader Role Does Have Access
Mar 1, 2007Hello (help),
In SQL2000, when the Guest account was assigned into a role, such as db_datareader, then querying across databases worked just fine.
Specifically:
I have a Report Writer application that connects to the SQL Server with a login (ReportRunner) that actually has very limited permissions on a database.
The connection is then set (sp_setapprole) to use an Application role (App_RR) that has the necessary permissions.
The report-writer app calls a Stored Procedure that gathers data from several other databases (on the same SQL instance).
In SQL 2000, accessing these other databases was done through Guest - we assigned Guest to the db_datareader role. All worked fine.
We've just upgraded to SQL2005: reports started failing. It seems that although guest is assigned to the db_datareader role, the permissions for Guest don't allow selecting from tables via the db_datareader role: we've had to GRANT SELECT TO Guest specifically on the tables necessary for the report.
Is anyone aware of a design change withing SQL Server such that the Guest principal's roles are disregarded when assessing permission? Is there a new and better way to structure the permissions?
Thanks in advance for your help.

SQL Security :: Unable To Change Guest Schema Owner
Jul 22, 2015One of our databases has at some point in its dark past had the owner of the guest schema changed to be a named user, rather than the default guest user. Correcting this feels like it would be easy enough by running the following...
  ALTER AUTHORIZATION ON SCHEMA::guest TO guest
but that results in..
  Msg 15150, Level 16, State 2, Line 3
  Cannot alter the schema 'guest'.
I realise the guest schema is a special one, and cannot be dropped, but I'm not trying to do that. End goal is to export the database to a SQL Azure DB, and this guest schema assignment is blocking that process from completing.
The Need To Reboot SQL 2000
Mar 26, 2002Our NT person thinks that rebooting the SQL 2000 (on WIn 2000) server every month is a good idea (this is a client production box). I am strongly against it. For starters any trends I am trying to capture with performance monitor become useless every time we do this. I am willing to listen to every one's opinion, but I hope by now that SQL 2000 is stable enough not to have to do this.
