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... :)

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.

Jul 30, 2007Hi
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

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.
Whether To Use Local System Account Or Domain Account For Service Account
Jan 5, 2006During install of SQL Server 2005, we can of course use a domain account or the built-in system account for running the services. I lean toward domain for obvious reaons but would like to know a +/- to each option and why I'd choose one over the other and what consequences or limitations one may encounter if I choose one over the other.

Dec 4, 2006I have been running a script in SQL Server 2000 as sa also as a Active Directory user who has administrator rights (I tested both approaches SQL Server then Windows Authentication) in Query Analyser which grants execute rights to the stored procedures within the database instance and Query Analyser does not give any errors when I run the script. I have made sure that each transaction has a go after it. I then return to Enterprise Manager, check the rights (I apply them to roles so that when we create another SQL Server user we just grant him/her rights to the role) and discover that the role has not been granted the rights.

Xp_cmdshell Does Not Execute For Non-sysadmin Account Even With Proxy Account
Mar 2, 2004Hi all, i hope you can help me.
Basically a dts package has been setup that pulls in data from another companies server, this data requires to be on-demand i.e individual users can pull in updates of the data when they require it.
I am using xp_cmdshell and dtsrun to pull in the data. This obviouly works fine for me as i am a member of sysadmin.
Books online quotes " SQL Server Agent proxy accounts allow SQL Server users who do not belong to the sysadmin fixed server role to execute xp_cmdshell"
So i went to the SQL Server Agent Properties 'Job System' tab and unchecked 'Non-sysadmin job step proxy account' and entered a proxy account.
The proxy account has been setup as a Windows user with local administrator privilages and even a member of the sysadmin server role - just in case.
Now when i log onto the db with my test account - a non-sysadmin - and attempt to run the stored proc to import the data i recieved the message 'EXECUTE permission denied on object 'xp_cmdshell', database 'master', owner 'dbo' '
hmm... so basically i have either misunderstood BoL or there is something not quite right in my setup.
I have search the net for a few days now and yet i can find no solution.
Can anyone help?
Domain Account Vs Local Account For SQLServerAgent
Jul 20, 2005Hi there,BOL notes that in order for replication agents to run properly, theSQLServerAgent must run as a domain account which has privledges to loginto the other machines involved in replication (under "SecurityConsiderations" and elsewhere). This makes sense; however, I waswondering if there were any repercussions to using duplicate localaccounts to establish replication where a domain was not available.Anotherwords, create a local windows account "johndoe" on both machines(with the same password), grant that account access to SQL Server onboth machines, and then have SQL Server Agent run as "johndoe" on bothmachines. I do not feel this is an ideal solution but I havecircumstances under which I may not have a domain available; mypreliminary tests seem to work.Also, are there any similar considerations regarding the MSSQLSERVERservice, or can I always leave that as local system?Dave

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.

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,
Zath

Domain Account Without A SQL Login Account
Apr 25, 2007I have a situation that I have discovered in our QA database that I need to resolve. When I looked at the Activity Monitor for our server, I discovered that a process is running under a domain user account for one of our .Net applications. The problem is that that domain user account has not been created as a SQL login account on the server. I am trying to figure out how someone can log in to the database server with a domain user account that has not been added to SQL Server as a login account.
Does anyone have any insight on this? I don't like the idea of someone being able to create domain account that can access the database without me granting them specific access.

SQL 2012 :: Security Risk Of Guest User
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.

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?

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.
URGENT: Problems With Guest User In SQL 2005 Restoring Databases From Sql 2000
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.
