Securing SQL Server Tables Linked Via Access
Jun 7, 2000
Hello,
We are currently live with a CRM solution (Siebel) that uses SQL Server 6.5 as the back end. All is fine and dandy, except I have some reservations about security.
Quite simply, it is possible for anyone to open up MS Access and link to any of the SQL Server database tables via the ODBC DSN used by the Siebel front end. This DSN is necessary for Siebel to function.
I am bit worried that someone (out of incompetence or spite) might do just that and cause some serious damage. Its probably technically beyond the large proportion of our users (especially those that could make mistakes!), but I can't get the nagging fear out of my head.
Does anyone know of anyway to combat this problem? I have scoured the web, including this site, and cant seem to get any information on this.
Thanks and Regards
Dike

on that Server if i go to SecurityLinked Servers
There is another Server is already mapped, when i am trying to see the Tables under that one of the
Linked Server i am getting the Error message saying that
"Error 17 SQL Server does not exist or access denied"
if i went to Production Server location and if i try to see the tables i am able to see properly, no problems
why i am not able to see from my Desk top
i am using the sa user while mapping the Production Server on my DESKTOP using (ENTERPRISE MANAGER)
And i check the Client Network Utility in the Alias using Named Pipe only, i changed to TCP/IP still same problem
What might the Problem how can i see the Tables in Linked Server from my DESKTOP
Thanks

is it possible to define in sql server linked tables to odbc data sources as it is possible to do in access?
except Access and vfp, is there another database that allows to create linked tables to odbc data sources?
I need to combine in a database native tables with odbc linked tables, but it would need to use a database more powerful that access or vfp

I am using two almost idential laptops, one with XP and one with Vista, the only differences is that the XP laptop has 1G of RAM and running Office XP and the Vista has 2G RAM and is running Office 2007.
I have a MS Access database that has linked tables to a SQL Server 2000 database. The performance of the Access database on Vista is 5-10 times slower on the Vista machine. Just flipping through records or opening forms can take 5 - 15 seconds on the Vista machine while the XP machine takes 1 sec or less.
What gives? I looked at the CPU performance and the network performance while the Access database was busy flipping through records, the network traffic was < 2% and the CPU would spike to 40% on one of the CPUs (dual core) but would remain under 5% most of the time.
I also previously had Office XP installed on the Vista machine and it had the same performance issue so bought and install Office 2007 on the Vista machine and it did not solve the problem.
It seems that Vista is doing something that is slowing down Access with linked tables. Is this a issue between Vista and using an ODBC connection to SQL Server?
Thanks in advance for any help on this

We migrated a MS Access 2003 mdb into MS Access 2007. The mdb has linked tables to SQL Server via a DSN and utilizes a mdw file. In 2003, the username/password is "passed" to SQL Server, so the UID/PWD that is used for opening the mdb, is used in SQL Server.
Opening the same file in 2007 using the same mdw, gives a secondary login on SQL Server.
Is there a way to have MS Access 2007 pass the UID/PWD to SQL Server on linked tables, the same way that 2003 does?
Thanks!

I have linked a number of tables from a SQL database to a Access front end. I am able to update all but one of the tables (the main table I need!!!). I get the error, cannot update record as it has been changed by another user although there is no other user. I believe it may be to do with the way the recordset is linked to the access database or the referential integrity of the table associations in the SQL database.
I can change the data using query analyser without issue.
Any help would be greatfully apreciated.

Having a little problem with linking to Access tables. I have an Access database that has in it, some linked tables. After setting up the linked server in SQL server, none of the linked tables in Access show up, only the tables that were created or imported show up.
Is there anything you can do to get the linked tables in Access to show up under the tables list in the SQL linked server?

Hey everyone. I've linke an access database and I am able to query the tables like so:
SELECT *
FROM QFinity...tblEmployees
I can do that to all the tables, however, I'd like to create a view to this linked database. Is this possible? I have a more complex query I'd like to run:
SELECT dbo_evaluations.eval_id, dbo_evaluations.quality_date, dbo_eval_questions.status
FROM QFinity...dbo_evaluations INNER JOIN dbo_eval_questions ON dbo_evaluations.eval_id = dbo_eval_questions.eval_id;
I get the error "Msg 208, Level 16, State 1, Line 1
Invalid object name 'dbo_evaluations'."
I'm afraid I've reached the limit of my know how concerning sql server 2005... I think I read that I need to create a view? But I can't figure out how to do that.
Thanks for any help!

Hi,
I've a bit of a problem that I'm stuck on.
I have a system that has the tables on an SQL Server with the front-end on a Microsoft access database. They are connected via odbc and the tables are linked to the access front-end. The odbc connects to the sql server via a user created for the purpose that only has rights to this database. This user has rights set so that they can access/alter any data in the database.
When my users try to alter data on some of the linked tables they get "The Microsoft Jet database engine stopped the process because you and another user are attempting to change the same data at the same time." This does not happen to every table only on some of them.
This happens even when there is only one user accessing the system. If I log into the enterprise manager I can alter those tables/ records without any problem (as some articles I’ve read say if the problem is connected to a corrupt record its not possible to then alter that record and sql server should give me an error message instead).
I have tired.
- Compact and repairing the access front-end.
- Deleting the links in the access front-end then re-linking them.
- Copying the objects from the access to a new blank access db.
- I have tried altering the account the odbc uses to login to the SA account.
- I have asked the server admin to do the 'compact and repair' on the s.q.l server, shrink I believe it is, as some articles suggest this could solve the problem.
- The admin has also tried this on the transaction files (so he has told me).
None of this has worked.
I'm stuck. I don't have any training on SQL server (nor will I be able to have any as I gather the training budget may be needed to fill some finance holes). If anyone has any idea of the answer to my problem or could point me in a direction that I could try investigating I would be very grateful. I have asked the admin if it’s anything to do with transactions, he has told me he does not know how to see those but he will try to find out if we can. Am I shooting in the dark or does this sound like a transaction/process locking problem? Is there something I should be looking for?
Thanks in advance.

Hello,
I am trying to update some SQL-linked tables in my Access database by repoiting the existing linked tables to a new datasource. The problem is, when I go to select the machine data source where the table sits, I get an error message saying the MS Jet Database can't find the object. This is because when Access creates the linked table, it replaces the period in the <schema>.<table_name> with an underscore. So when I go to update the links, it is essentially looking for the new table with the wrong file name.
I have about 80 linked tables to update and I haven't been able to figure a work-around. HELP PLEASE!
Cheers,
Josh

Hye guys,
I am not the perfect database designer nor the programmer. I have designed and developed a simple database application which uses VB as frontedt and SQL as backend. My Program worked fine.. Now I have 2 deploy it in clients computer where DBA is another person by which I am worried abt the data in the table. As X person is a DBA there he can easily change data of my tables in the database.
So I want an easy way by which the X person can't edit the data of the tables of my database only I can change the contents of my tables but i should be able 2 change the data from my program only..
Plz Help..

We have an application written in MS Access. The tables are linked to a SQL 2000 database.
The problem is that sometimes insert a new record in a table freezes and times out after a while without anything has happened.
When installing the application the *mdb file is copied over to the C drive and an ODBC connection is written to the registry.
The application is used by many in the company.
We have problems on tables defined with IDENTITY columns. Can this be our problem and how can we solve it?

I am using the following select statement to get the row count from SQL linked server table.
SELECT Count(*) FROM OPENQUERY (CMSPROD, 'Select * From MHDLIB.MHSERV0P')
MHDLIB is the library name in IBM DB2 database. The above query gives me only the row count of table MHSERV0P. However, I need to get the names, rowcounts, and sizes of all tables that exist in MHDLIB librray. Is it possible at all?

Hi,
I am running SQL Server 7.0 and am trying to set up a linked server to an access database so I can use a SQL7 stored procedure to update the access database.
I create the linked server as:
sp_addlinkedserver @server = N'LinkedServer',
@srvproduct = N' ',
@provider = N'Microsoft.Jet.OLEDB.4.0',
@datasrc = N'MyServerest2.mdb',
@catalog = N''
GO
I then try setting up the security in the security tabs to impersonate a user I have set up in the access database.
I also have NT security on the directory of the access database to limit the users who can access the directory.
My problem is that when I try to run the sql:
"select * from LinkedServer...IMS" (IMS is the tablename) I get the following error:
Server: Msg 7399, Level 16, State 1, Line 1
OLE DB provider 'Microsoft.Jet.OLEDB.4.0' reported an error.
[OLE/DB provider returned message: The Microsoft Jet database engine cannot open the file 'ASPECT04accpactestest2.mdb'. It is already opened exclusively by another user, or you need permission to view its data.]
If I add "Everyone" tpo the security level on the NT directory it works fine, so I obviously have a security problem.
Can anyone tell me what user the sql is running under.
any ideas of the best way to set this up.
many thanks for the help
dave

I am new to SQL server. I have a pbm setting up a linked server to MS Access using ODBC. My MS Access database is in the Netware server. I have mapped the NT server to this Netware server using a binary account. Then I have setup the ODBC connection. I tested the ODBC its ok. But when I try to view to tables in the Linked server it gives me an error "Disk or Network Error". I am breaking my head for the past few days. If you have any solution. Pls reply. Thanks in advance.

After converting to SQL Server 2005 and VS2005 I am having a problem connecting to Linked Servers for Access databases. I have searched and read everything I can find, but the solution is still not evident. I have a lot of data integration and data conversion procedures to run and I am stuck at this point not understanding exactly what the problem is and how to resolve it. I believe it is somehow related to "double hop" and permissions with .NET. Many of the discussions are related to using .ASP but that is not involved in this situation.
The Linked Server is defined using the UNC path. The machines are not in a domain. They are in the same LAN segment. Connections will be made without using a security context is specified. A sample Linked Server definition:
EXEC master.dbo.sp_addlinkedserver @server = N'ACCESS EDUCATION', @srvproduct=N'OLE DB Provider for Jet', @provider=N'Microsoft.Jet.OLEDB.4.0', @datasrc=N'\Tacir2k3InfrastructureDatabasesJuly 2005 DatabasesEducationEduDb2005_TR_Db.mdb'
The error:
OLE DB provider "Microsoft.Jet.OLEDB.4.0" for linked server "ACCESS EDUCATION" returned message "The Microsoft Jet database engine cannot open the file '\Tacir2k3InfrastructureDatabasesJuly 2005 DatabasesEducationEduDb2005_TR_Db.mdb'. It is already opened exclusively by another user, or you need permission to view its data.".
Machine 1 (Developer Workstation): XP SP2 with latest security patches; SS Management Studio, VS2005
Machine 2 (SQL Server server): Windows 2003 Server with SS2005. The Linked Servers are defined on an SS2005 instance on this machine.
Machine 3 (File server): Windows 2003 Server that contains the Access DB files
When I run SS Management Studio on Machine 2 (the database server), I have no problem accessing the Linked Server pointing to an Access DB file on Machine 3 and can compile or run SPs referencing the Linked Server.
When I run SS Management Studio on Machine 1 to execute an SP that references the Linked Servers, I get the above error.
When I use Machine 1 to compile an SP that references the Linked Server, I get the above error.
I tried granting Everyone Full Control to the folder that contains all the Access database subfolders but I get the same error when running from Machine 1.

I am trying to configure a linked server to a local Access database with no security and only one table.
I set it up and tested on a test machine first and all works fine. I then did the same on our production box and receive the error below.
Server: Msg 7303, Level 16, State 2, Line 1
Could not initialize data source object of OLE DB provider 'Microsoft.Jet.OLEDB.4.0'.
[OLE/DB provider returned message: Not a valid account name or password.]
I then set it up on another production box and it worked for a while but now I get a different error.
Server: Msg 7399, Level 16, State 1, Line 1
OLE DB provider 'Microsoft.Jet.OLEDB.4.0' reported an error.
[OLE/DB provider returned message: Cannot open database ''.
It may not be a database that your application recognizes, or the file may be corrupt.]
Is there a server level setting that could be different on these machines that could be causing this?

Hi,
I have an Access database (name "Shipping") linked to SQL Server. The Access database is not secured. My access file is located on the same machine as the instance of SQL Server, in a shared folder that can be accessed by any user. The file permissions are set to full control for Everyone. I linked Access with the following procedure:
EXEC sp_addlinkedserver
@server = 'Shipping',
@provider = 'Microsoft.Jet.OLEDB.4.0',
@srvproduct = 'OLE DB Provider for Jet',
@datasrc = 'C:ShippingShipping BackEnd.mdb'
then modified the linked server login mapping with:
EXEC sp_addlinkedsrvlogin 'Shipping','false',NULL,'Admin',NULL
Now, since I have domain administrator permissions, I can run a stored procedure in SQL Server that does a Select in the Access database without any problem. But when a normal user tries to run the procedure, he gets an error #7399. If I give this user domain administrator rights, he's able to run the procedure. There is something I don't get, with normal user permission, this user can open the Access database through the shared folder...
Thanks

Hi,
I'm working with MSSQL2K+SP3a, Standard Edition. I defined linked server (MSDE).
On the local server, I can do
select * from [testDB].[INFORMATION_SCHEMA].[TABLES] -- local
select * from [testSRV].[testDB_far].[dbo].[sysobjects] -- linked
but not
select * from [testSRV].[testDB_far].[INFORMATION_SCHEMA].[TABLES]
How can I access the INFORMATION_SCHEMA on the linked server ?
Thanks,

I'm trying to create a linked server to an Access database that resides on a separate machine.
On my PC, I can create a link to the Access db, and view, update, add and delete data. If I create the same linked server on our production Server, I can again view, update, add and delete data. All's well so far.
If I now go back to my own PC (used for developing) I cannot access the linked server on the production machine.
The Access database is stored on a separate PC, so the I'm linking to a remote db. As I said this works fine if I'm sat in front of the PC that the linked server is created on - but not if I use a client PC to connect.
I create the linked server using the following command:
exec sp_addlinkedserver
@server = 'AccLinkedServer',
@provider = 'Microsoft.jet.OLEDB.4.0',
@srvproduct = 'OLE DB Provider for Jet',
@datasrc = '\DatabaseServerAccessDatabase.mdb'
If I run the SQL statement:
SELECT * FROM AccLinkedServer...AnyTableYouLike
I get this error:
Server: Msg 7399, Level 16, State 1, Line 1
OLE DB provider 'Microsoft.Jet.OLEDB.4.0' reported an error.
[OLE/DB provider returned message: The Microsoft Jet database engine cannot open the file '\DatabaseServerAccessDatabase.mdb'. It is already opened exclusively by another user, or you need permission to view its data.]
OLE DB error trace [OLE/DB Provider 'Microsoft.Jet.OLEDB.4.0' IDBInitialize::Initialize returned 0x80004005: ].
I've searched in the MS knowledge base, and this forum and followed all of the advice that was available, but it still won't work.
Anyone got any other advice, before I go totally insane with this.
Cheers.

There seems to be a lot of confusion around the groups about linkingto an Access mdb with the SQL Server Jet OLE DB provider and I haventbeen able to find a straight forward solution. Basically, I have anAccess MDB (A2K) on one server and a SQL Server DB (2005 std ed.) onanother - Both on the same network. I'm trying to create a linkedserver object in the SQL server to view data in the mdb. I've set itup and it works - but only from the server machine itself. If you tryto connect the the linked server from any other computer on thenetwork you get the usual access denied / file in use error.The fact that I can use the linked server from the server box itselfbut not from another pc on the network makes me think that it may be apermissions problem. But I am logging in with full Admin rights andstill no joy. Also there is no workgroup security on the mdb, so thatsnot the problem. I've used the surface editor to remove anyrestrictions that may cause problems, OLE DB connect, OPENROWSET etc.but still no joy.I've tried mapping the mdb's location on the server so I could use astandard filepath, rather than a //Server-Name/... path. Again, worksfrom the server, but not from any client PCs, so no joy there either.In frustration, I copied the mdb to the same server and viola - fullaccess to the linked server from anywhere. But this is no good, I needthe mdb file to stay where it is. An mdb full of linked tables wontwork... they don't show up in the linked server.So that's it - out of ideas! Am I just going to have to accept thatlinked server objects are limited just to mdb files on the same servermachine, or is there something I'm missing??? Firewalls, servicelogins, server settings.... something one of you gurus out there knowabout that might be the key to making my headache go away!!!Any input gratefully recieved!!!

I've set up a linked server to an Access database and read from the linked database in a stored procedure. No problems when I execute the stored procedure from management studio and the Access database resides on a local drive.
However, when I move the database to a network share drive and run the proc through a scheduled job using SQL Server Agent I get the following error --
"Executed as user: C-SGROUPactprod. Access to the remote server is denied because the current security context is not trusted. [SQLSTATE 42000] (Error 15274)."
I've spent days trying to resolve this problem and tried many different setting to fix the problem, but no luck yet.
Under the Security setting for the linked server I have "Be made using this security context" selected with a valid id/password. I am able to login to the server where the database resides using the id and password and successfully open the database.
Don't know what to try next. Any suggestions?
I'm using SQL Server 2005 Developers edition.
Thanks.

Hello,
I currently am in charge of creating a Sharepoint 2003/Exchange 2003 ticketing system. We have a client database (MS Access 2003) that has a linked table to our Exchange store, retrieving information we enter in Exchange regarding specific clients. I would like to move this database to SQL Server for performance reasons. Soon there will be many people accessing this database and I don't want the bottle neck to be Access.
The only quirk I can think of is, can one link a table from SQL Server to Exchange. Or for that matter, can SQL Server have linked tables at all? One solution I can think of is to create a System Service that runs on the server, to periodically update the SQL table with the information in the Exchange store. But that could become costly over time with large amounts of network bandwidth being used for unnecessary updates.
Is there maybe another solution I'm not seeing? Should I just stick with the Access database?
Thanks
Josh

I just finished up setting up linked server from one of my database machines to another. After futzing to get permissions just right, it works great for many things:
select top 5 * from altai.prep.dbo.simulation_status
0 Prepping Simulation is being prepped by the owner.
1 Prepped Simulation has been prepped by the owner.
2 Checking Simulation is being checked by the owner.
3 Checked Simulation has been checked.
4 Running Simulation is running.
I can even see tables using sp_tables_ex:
sp_tables_ex 'ALTAI', 'S%', 'dbo', 'prep', NULL, 1
TABLE_CAT TABLE_SCHEM TABLE_NAME TABLE_TYPE REMARKS
-------------------------------------------------------------------------------------------------------------------------------- -------------------------------------------------------------------------------------------------------------------------------- -------------------------------------------------------------------------------------------------------------------------------- -------------------------------------------------------------------------------------------------------------------------------- ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
prep dbo Simulation TABLE NULL
prep dbo Simulation_References TABLE NULL
prep dbo Simulation_SimulationGroup TABLE NULL
prep dbo Simulation_Status TABLE NULL
prep dbo SimulationGroup TABLE NULL
(5 row(s) affected)
The trouble is, I have another table in this database called that begins with "S": Staging_Transition_States. If I try to access this table via the linked server, I get:
select * from altai.prep.dbo.Staging_Transition_States
Msg 7314, Level 16, State 1, Line 1
The OLE DB provider "SQLNCLI" for linked server "altai" does not contain the table ""prep"."dbo"."Staging_Transition_States"". The table either does not exist or the current user does not have permissions on that table.
This table exists, sp_help for this table is below. Why doesn't this table show up in the output of sp_tables_ex? As far as I can tell, permissions for the tables that work and this table are identical.
Thanks!

Hi all,
I have been given a task of securing an SQL server 2005 that is currently open to SQL injection attacks. I have identified 3 main areas that I need to secure, these being:
1.Different SQL server logins - currently all database work from the site is performed using the sa account (don't ask me why they've left it so open to attack, I've not long started here!)
2.Custom error pages - to reduce feedback to a potential attacker on the database structure
3.Query Validation - any dynamically generated queries will be passed through a validator in order to possibly strip out any commands that we identify as those that an attacker would attempt to pass via the url.
Obviously, point number one is the big one. Based on this, my question is, what are the series of steps I would need to go through in order to;
a) setup a user login that has read access to many of the database tables (and execute access to some of them)
b) setup a user login that has read/write/update/execute access to other tables and stored procedures
I have read a lot about schema's, but I haven't had that many dealings with SQL server 2005 (yet), and haven't been able to find a step-by-step guide to setting up a schema/users and assigning permissions to them.
If someone could point me in the right direction of an "idiots guide to", that would be great, or if theres anyone that could list the steps I need to perform, that would be even better.
Also, if anyone has any other suggestions about how i could secure the server, I am all ears.
Thanks in advance,
Paul

What is the best way to keep the data secure in my SQL Server 2005? and what is the best way to secure the communication between the client application and SQL Server 2005?

Could anyone shed some light on the syntax of accessing system function on a linked server?I'm trying to get the recovery models of databases on a linked. However using databasepropertyex locally generates wrong results.e.g. select databasepropertyex(name, 'recovery') RecoveryModel from [server/databasename].master.dbo.SysDatabases I tried select [server/databasename].databasepropertyex(name, 'recovery') RecoveryModel from [server/databasename].master.dbo.SysDatabases which does not work. Thanks.
