Cannot Create An Instance Of OLE DB Provider SQLNCLI For Linked Server SERVERNAME, Error: 7302
Mar 2, 2008
I just installed a SQL Server 2005 Express SP2 instance on a server with an existing SQL Server 2000 SP3 installation. (I need SQL Server 2005's INSERT from an EXEC capability). It's working great now except for one thing: I can't link any other SQL servers! I've already successfully added and queried a linked Oracle server, but attempting to add a linked SQL server gives me the following error, no matter which SQL provider I try to use:
Code Snippet
"The linked server has been created but failed a connection test. Do you want to keep the linked server?"
Additional information:
--> An exception occured while executing a Transact-SQL statement or batch (Microsoft.SqlServer.Express.ConnectionInfo)
--> Cannot create an instance of OLE DB provider "SQLNCLI" for linked server "SERVERNAME". (Microsoft SQL Server, Error: 7302)
The technical details reveal the error source as "sp_testlinkedserver".
I've scoured the net and premier support for advice on this problem, but the little I found wasn't helpful. I've tried reinstalling the SQL Native Client, but it didn't help. I've tried uninstalling SQL Server 2005 Express completely (including management studio and native client), rebooting, and reinstalling everything, with no luck. The server (obviously) does not have a firewall enabled. I've tried stopping the SQL 2000 Server installed on the system, no help. If I create a test .UDL file on the system, pointing to any of the SQL servers I'm trying to link, clicking the "Test Connection" button returns successful. I'm also able to connect to and query the servers directly from the SQL 2005 Express Management Studio. I just can't add them as linked servers.
The server is running Windows 2003 SP1, SQL Server 2000 SP3, and SQL Server 2005 Express SP2 (the default "SQLExpress" named instance). I've tried setting up SQL 2005 Express to run under the network service account and under a domain account used by the other SQL 2000 servers.
From other SQL 2000 servers, I can connect and link to the SQL Server 2005 Express instance successfully. I can also successfully add linked SQL servers in SQL Server 2000 instance installed on the same server. Only adding linked SQL servers in 2005 Express seems to be broken.
Anyone have any other suggestions? I'm totally baffled. Thank you so much for any helpful advice.

Hello, I've a problem with a software developed in C# with the framework 2.0. This is the error I receive : The operation could not be performed because OLE DB provider "SQLNCLI" for linked server "XXX_LINKED_SERVER" was unable to begin a distributed transaction. OLE DB provider "SQLNCLI" for linked server "XXX_LINKED_SERVER" returned message "No transaction is active.". If I try directly to restart the process, it works fine. Is there someone who can help me ? This is the process 1. In C# --> Call of a Query : select from the linked server (db in sql 2005) and insert into a table SQL 2005 2. In the C# --> using (TransactionScope scope = new TransactionScope()) and insert in a table in SQL 2005 which is link server Thank in advance.

System: Win 2003, SQL Server 2005, Using an AD win account that is not a member of the Admin group on the server.
Error message from Management Studio query window:
Msg 7302, Level 16, State 1, Line 1
Cannot create an instance of OLE DB provider "IBMDADB2" for linked server "Sname".
Event messages associated with this error:
App Event ID: 19036
The OLE DB initialization service failed to load. Reinstall Microsoft Data Access Components. If the problem persists, contact product support for the OLEDB provider.
Sys Event ID: 10016
The application-specific permission settings do not grant Local Activation permission for the COM Server application with CLSID {2206CDB0-19C1-11D1-89E0-00C04FD7A829}
to the user domainuser SID (S-1-5-21-126051702-1034962659-2130403006-7826). This security permission can be modified using the Component Services administrative tool.
I€™m getting this error message when trying to run an openquery statement through a linked server to DB2. (SELECT * FROM OPENQUERY(Sname, 'SELECT * FROM tablename€™))
The linked server has a remote login and password that it uses to connect to DB2.
I found this from another post on how to fix this error:
Expand Component Services - Computers - My Computer - DCOM Config Select MSDAINITIALIZE Right Click properties then security
Under Security - Launch Permission: enable Local Launch and Local Activation for your SQL Service account
Under Security - Access permissions: Allow System: Local Access and Remote Access.
After completing these steps I still get the error message but the events are no longer generated. I€™ve also tried different variations of these steps. The only way I can get this to work is to either make the AD user a member of the Admin group on the server or by putting in a user account that has admin rights to the server in the MSDAINITIALIZE properties €“ Identity Tab €“ Run this App as this User.
Can someone please tell me the steps that I€™m missing?

Ok here is a run down of the situation:
I'm running Server 'A' and Server 'B' which are both on SQL 2005 SP2. Server B connects to Server A using the linked server functionality via the SQLNCLI provider. I am issuing an update statement from a web api in a nested transaction that uses a distrubted transaction.
However, I am receiving the following error :
Unable to start a nested transaction for OLE DB provider "SQLNCLI" for linked server "A". A nested transaction was required because the XACT_ABORT option was set to OFF.
OLE DB provider "SQLNCLI" for linked server "A" returned message "Cannot start more transactions on this session.".
I've researched the issue and understand how XACT_ABORT works.
Also, I looked at the Linked Server provider options for SQLNCLI and came accross the Nested Queries option being unchecked. I checked the option and applied it to the Linked Server.
Okay, so after my long post my questions are: Do i need to restart SQL in order for this to take effect? If not, what do i need to do? I 've restarted IIS to no avail .

I find this most perplexing.
I have two servers, DEV and PROD. Now my DEV server works just great, I can connect to the linked server, query, etc... all is well.
So I'm setting up my PROD server and when I go to add the linked server I get:
Cannot initialize the data source object of OLE DB provider "SQLNCLI".... and Unable to complete login process due to delay in opening server connection.
Now I am running SQL Server 2005 and connecting to an SQL 2000 server.
The odd part is that this works just fine on DEV.
When I go to create the linked server I set:
Linked Server: "LinkedServerName"
Server Type: "SQL Server"
and that's it.
I go to Security and enter my DOMAINUSER.ACCOUNT and then enter the login creds for the linked server.
When I click "OK" I get the above mentioned error code.
Any thoughts?

I've been assigned with finding the issue behind this error on one of our production systems:
TCP Provider: The semaphore timeout period has expired. [SQLSTATE 07008] (Error 121) OLE DB provider "SQLNCLI" for linked server "SERVER1" returned message "Communication link failure". [SQLSTATE 01000] (Error 7412). The step failed.
I've Googled the error to death, searched the forums here and at other SQL sites as well and have found nothing that points me at the cause. I've found the individual parts of the error but not the whole. Maybe I've just been looking at it too long and am missing something simple. Anyone have any ideas?
These are two linked SQL2005 64bit enterprise Win2k3 servers. The error comes when an automated daily job is run. Sometimes it happens at once, sometimes after 5 minutes, sometimes after an hour. I can see nothing wrong with the server itself or the network.
Thanks in advance.

I am linking to another SQL Server database to extract data into my own system. Following an increase in size on one of the columns in a table I am extracting, I am getting the following error:
'OLE DB provider 'SQLNCLI' for linked server 'gsc-rpt.svr.bankone.net' returned data that does not match expected data length for column '[gsc-rpt.svr.bankone.net].[Peregrine].[dbo].[scProblem].short_description'. The (maximum) expected data length is 100, while the returned data length is 148'
The column short_description has been increased from 100 to 1024. Writing a simple query, SELECT (max(len(short_description)) FROM dbo.Peregrine_Problem will generate the error, but if I embed the same SQL into an Excel VBA macro and connect to the server, it happily returns the result 1024. Our Access databases also link to the table on the remote server and handle the increased column size properly.
I have done everything I can think of, including deleting the linked server within SQL Server MS, and recreating it, but I can't override the setting of 100.
Any ideas?

I have 2003 server installed on my machine along with MS SQL Server Management Studio and I am able to connect fine to SQL 2000 Instances. On my laptop running Vista Enterprise, I can not connect to these exact same instances via MS SQL Server Management Studio as I am getting the above error. Does anyone else have this problem? I have no idea what to check for anymore. Thanks in advance.

Ok can somebody please explain to me why only 1/2 my project is getting this error. I am working with SQLExpress on a remote windows 2003 box. The sql server has its service running and the browser is also running. The server has been set to allow remote connections and to accept TCP/IP and Named Pipes. Now, the website uses asp.net membership and roles to allow the users to login, which actually works. So I know that there are no errors in that connection string. However, all the data acess code is compliled as a sepeate class library thats referenced in the bin directory. When calling those methods to beind to a control in code, is where i run into this error. The class library connection string in the app.config file is exactly the same as the connection string in the web.config...i have checked permissions as well, im at a loss to the reason why this is not working....its probably something simple, but im not finding it.
On a seperate note - How do i get the remote database to show up in the server explorer on vs2008, i have tried putting in the ip addressinstance name, and a combo of there items, it will not connect. I have a feeling the two issues are connected. Also fyi, on the remote box, I am able to login with the sql studio express, so im not really sure exactly wuts gong on. Both items are really important and i need to be able to use both of them.
Thanks,
Jeremy

I made a simple ASP.NET 2.0 Website that uses memberships, roles, and access to MS SQL Server 2005 database. Everything works fine on my development computer (WinXP Pro). When I deployed this Website on another computer (WinXP Pro) and tried to access the main page from the same computer, I get the error below.
I disabled the Windows Firewall (the only one I use), I ensured that SQL Server Browser is Active and Running, and I changed Remote Connections in SQL Server 2005 Surface Area Configuration to use Local and Remote connections for all the components.
In my Web.Config I used:
<connectionStrings><add name="sqlConnString" connectionString="Data Source=.SQLEXPRESS;AttachDbFilename=|DataDirectory|DBdemo.mdf;Integrated Security=True;User Instance=True" providerName="System.Data.SqlClient"/></connectionStrings>
Any idea why am I getting the following error?

All,
One of our developers decided to load 2K5 client tools on to their laptop. They cannot connect getting the following error:
....Error: 26 Error Locating the Server/instance specified (.NET SQLClient Data Provider)....
1.) Allowing remote connections IS enabled.
2.) SQL Browser Service is ON
3.) Windows Firewall is NOT running
4.) All protocols (except VIA) are enabled
Others at this office, including myself, can connect fine in Management Studio. Only this one developer cannot.
Any thoughts and/or help would be much appreciated. I think that the problem has something to do with the first sentance above but I am not positive.
Thanks in advance,
DBA Ben

This problem happens on this particular machine and doesn't happen on other machines that I have. And I think this problem belongs to this forum. Because the problem is triggered by a special setting in the connection string.
I followed the steps of threads including Xinwei Hong's instruction for fixing this error(26) but has no luck.
The problem occurs when I call SqlConnection.Open().
I am using window xp, sql2000. the named instance is on local machine, my connection string is like
"Data Source=MSL-1417762\SQL2000;Initial Catalog=PopulateForeignKeys_MSL_1417762_2_5984;Integrated Security=True;Pooling=False;Asynchronous Processing=true"
Whenever I change Asynchronous Processing=true into Asynchronous Processing=false, the problem is gone.
This problem also occurs when I use Visual Studio - Server Explorer - Add Connection dialog - Advanced button - Advanced Properties window where you can set Asynchronous Processing property to true.
Can you please help?
Thanks,

Run this script:
bulk insert viewdisp
from 'd:downloadsassessment05_preloadviewdisp.txt'
with (
check_constraints,
datafiletype = 'widechar',
firstrow = 1,
maxerrors = 0
)
go
Get this error:
Could not create an instance of OLE DB provider 'BULKIMPORTSTREAM'.
OLE DB error trace [Non-interface error: CoCreate of DSO for BULKIMPORTSTREAM returned 0x80040154].
SQL Server 2000 - SP3a
Logged in as sa with system admin, bulk insert admin, dbo, ddl admin, local admin, king of the world... you name it.
Is this a OLE DB Driver or MDAC issue?
Anyone else ever had this issue. You would think that Microsoft would have all of their error messages on their own WebSite, but that must be too much trouble for them.

Hi forum
I'm developing a report in SQL Server 2005 Reporting Services based on a query from SQL Server tables joined with Visual FoxPro free tables. I created a Linked Server with Microsoft OLE DB Provider for Visual FoxPro provider, whith VFPOLEDB.1 string provider. Everything runs ok
within a Business Intelligence Development Studio environment, but when I implement my report, at runtime an error occurs it said "Cannot create an instance of OLE DB Provider VFPOLEDB object". I swtched any combination of Linked Server security and Provider security pages without to solve the problem.
Navigating the web today, I read a similar thread posted by stephanielauym
at April 3, 2006 but I`m not clear if she passed the issue or not. In case of yes, I would like to know how she solved it. I'proved among other with "Allow inprocess" but don't.
Please, if Stephany or Cindy (that she answered) or anyone knows how to solve this error, I'll thank very much.

Hello all,
I want to create a table in MS-Access. So I have written the following query.
Code Snippet
select * from Openquery(KKACC, 'select * Into Temp from Table select 1 as col1')
But I am getting the following error.
Code Snippet
OLE DB provider "Microsoft.Jet.OLEDB.4.0" for linked server "KKACC" returned message "Syntax error in FROM clause.".
Msg 7321, Level 16, State 2, Line 1
An error occurred while preparing the query "select * Into Temp from Table select 1 as col1" for execution against OLE DB provider "Microsoft.Jet.OLEDB.4.0" for linked server "KKACC".
How can I resolve this error. Does any one have any work arround for this..?
Thanks

We have a SQL2005 server install running on a Win2003 Server. It has a linked server to iHistorian using the iHOLEDB provider for iHistorian. Randomly and after a few execution to this provider, we start getting errors
Msg 7303, Level 16, State 1, Line 2
Cannot initialize the data source object of OLE DB provider "IhOLEDB.iHistorian" for linked server "fspheafhs1".I created a data source in VS2005 for BI on the SQL server using the iholedb provider. This was successful. However, all queries or OPENQUERY statements to the linked server fail. This seems to continue until SQL Server is restarted. Does anyone know how to reset a provider in SQL Server or tell if the SQL Server is having trouble with the provider? There are no message in the SQL Error Log. Again the provider continues to work outside of SQL Server, but no longer can be accessed from within SQL Server. Thanks in advance.

Hallo
i'm trying to connect a VFP DBC as a linked server on MSSQL2000sp3a, using following parameters:
Product name: VFP
Data source: \networkpath odbc
Provider: VFPOLEDB.1
No security context
I'm trying the same operation both from a W2000sp4 server (+ MDAC 2.8sp1 ?) and a WXPPsp2, against two identical copies of the DBC that resides on two different path (one on the final path and one on a test path).
From WXPPsp2 everything runs ok, from W2000 i'm always getting this error:
Error 7399: OLE/DB Provider 'VFPOLEDB' IUnknown::QueryINterface returned 0x80070005: Access Denied
(already reported in this thread, http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=1832362&SiteID=1 but it didn't helped me)
The error happens independently from the user the query runs under (basicly AD account, both domain admin and normal user).
MSSQL runs under a domain account which have full permissions (for test purpose) on the directories where DBC reside.
I did no further modifications on the WXP machine in order to have the linked server running, simply it ran smoothly from the beginning.
Clearly the difference rely on the different OS... but what else?
i ran component checker to determine the MDAC version but some components version numbers slightly differs from the expected ones (eg. resulting version is 2.0.1064 versus 2.0.1022 expected in MDAC 2.8) so i suppose to have MDAC2.8 sp1 on the server.
thanks in advance

Hello, everyone!
I'm currently having an issue with a linked server. Here's the surrounding information:
A) I have a clustered SQL Server 2005 Instance (A) and a SQL Server 2000 instance (B).
B) There is a linked server on A to B. When I set it up, I did run the fix to ensure A could talk to B (There was an issue with communication between 2005 and 2000 servers). It has been there since I installed A, and has worked fine.. Until last week.
C) This linked server uses static credentials to connect to B.
D) Named Pipes are enabled on both servers to listen to both connections on both A and B in cliconfg. So A has a named pipe listening for B, and B has a named pipe listening for A.
E) A has a view that looks at a table on B - It's a table view, very simple, just pulls in all the data from the table on B.
So, I go to do a select statement from the view, connected as a user other then 'sa'. I then get the error:
Named Pipes Provider: Could not open a connection to SQL Server Linked Server
Error Source: ncli Client (Paraphrasing, didn't copy that down, but it was the ODBC connector)
Well, that's odd. It's been working fine for months now..
I then go and connect as sa on A to query B. It works! Mind you, absolutely NO QUERY from A to B will run again until I run SOME kind of query has been run as sa on A.
Mind you, this is not a credential issue. Every user who connects to the linked server to B uses a stored credential that is DBO to the database on B. The same User Name and Password exists on both A and B.
Also of note, I check the activity monitor. There's a process that is "dormant" every time I run a query against the view. The details of this connection are:
sp_reset_connection;1
My question is, why is it resetting the connection on B when being queried from A? Why is it "all of a sudden" a problem? Are there any changes that coudl ahve been made that would cause this?
Any help with this confusing issue would be appreciated.
Thanks!

Does anyone know how to configure a mirrored pair as a linked server on a 3rd instance?
Say I have a mirrored database on two servers: PRIMARY and SECONDARY.
I want to create a linked server on a 3rd machine that allows me to access the database on the mirrored pair.
This is what I'm using:
EXEC master.dbo.sp_addlinkedserver
@server = N'MIRROR',
@srvproduct=N'',
@provider=N'SQLNCLI',
@provstr=N'Server=PRIMARY;FailoverPartner=SECONDARY;'
select count (*) from mirror.pubs.dbo.authors
and it works fine if the database on PRIMARY is alive. however when the mirror has failed over to SECONDARY and PRIMARY is no longer available, I get the following when I try to query the database via the linked server:
OLE DB provider "SQLNCLI" for linked server "MIRROR" returned message "Login timeout expired".
OLE DB provider "SQLNCLI" for linked server "MIRROR" returned message "An error has occurred while establishing a connection to the server. When
connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections.".
Msg 10061, Level 16, State 1, Line 0
TCP Provider: No connection could be made because the target machine actively refused it.
As far as I can tell, it doesn't try to contact SECONDARY at all. It seems like SQL Server is ignoring the FailoverPartner attribute.
If I switch PRIMARY and SECONDARY in the connection string (ie @provstr=N'Server=SECONDARY;FailoverPartner=PRIMARY;') then it works when SECONDARY is online, but not when the mirror has failed back to PRIMARY.
Any ideas?
Piers.

Hi,
I'm working on an OLE DB provider. This provider is supposed to retrieve data from managed application running in background. The data retrieval is handled by C# component communicating with source application via remoting, the data are then exposed via component's COM interface. OLE DB provider itself instantiates the communication component.
Now, the problem: this worked ok in SQL server 2000, but it doesn't seem to work in SQL server express edition. Concretely, the communication component fails to get created (CoCreateInstance ends with 'class not registered') and SQL server logs this:
2007-08-24 14:48:49.42 spid51 Error: 6511, Severity: 16, State: 20.
2007-08-24 14:48:49.42 spid51 Failed to initialize the Common Language Runtime (CLR) v2.0.50727 with HRESULT 0x80131022. You may fix the problem and try again later.
I've googled a bit and found out someone else getting this message, and he was told something like 'trying to load CLR in some cases is disabled in newer (>2000) versions of SQL server'.
Now, I have very little knowledge of SQL server, CLR integration etc., so I'm not sure whether this applies to my case as well, but I think so - that problematic COM object is C#-based.
I'd be glad for any hints, ideas how to solve this issue, I just need the OLE DB provider to be able to access that managed application.
Thanks,L.

hi guys,
I'm using MS SQL Server 2005 with MDAC 2.8. When I test my project into TCP/IP, the project does not pick the records completely.
My connection string is using Provider=SQLNCLI.1
Do I need to install SQL Native Client to work-stations ?
Do I need to remove the MDAC ?
Than you.

I've successfully created a Linked Server that connects a local DB Engine with another DB Engine through an ip over an extranet. I am able to run simple Select statement queries on the Local DB Engine and get results from the linked server. However when attempting to perform more complex queries that join tables from the linked server with tables from the local DB server, I get the following error message after several minutes of execution:
OLE DB provider "SQLNCLI11" for linked server "<ip of Linked Server>" returned message "Protocol error in TDS stream".
OLE DB provider "SQLNCLI11" for linked server "<ip of Linked Server>" returned message "Communication link failure".
Msg -1, Level 16, State 1, Line 0
Session Provider: Physical connection is not usable [xFFFFFFFF].
OLE DB provider "SQLNCLI11" for linked server "<ip of Linked Server>" returned message "Communication link failure".
Msg -1, Level 16, State 1, Line 0
Session Provider: Physical connection is not usable [xFFFFFFFF].
OLE DB provider "SQLNCLI11" for linked server "<ip of Linked Server>" returned message "Communication link failure".
Msg 10054, Level 16, State 1, Line 0
TCP Provider: An existing connection was forcibly closed by the remote host.
How I can resolve it. I've read on Distributed Transactions but I understand that it only applies to manipulation statements?
Both are SQL servers. Linked Server is SQL2008R2 if not mistaken. Local DB Engine is SQL2014.
