Can I Have Link Between Several Servers
Sep 5, 2007
hello all
I have a web application(asp.net) and Database(sql server 2005) .
we have installed them on several servers.
now we want to have a connection between apllication on one server to a database on another server .
for example we have Server(A) and Server(B) the DataBases and Web apllications on two server are the same.
sometimes the Apllication on server(A) must connect to database on server(B).
whats the solution plz?
note that the number of servers can be inceased in the future this mean the number of servers are not fixed.
thanks

want to fetch the records from the server B in DB2. My query is
select * from B.DB2.dbo.table1
when i issued this statement in server A from database DB1 got the following error...
OLE DB provider "SQLNCLI" for linked server "B" 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.
Msg 18456, Level 14, State 1, Line 0

I am trying to implement a linked server that uses integrated authentication on a 64 bit Wndows 2003 SP1 server. I have both Sql Server 2005 and Sql Server installed, and have successfully created database link that is able to use double hop authentiction on the Sql Server 2005 instance. I am unable to do the same usign the Sql Server 2000 instance. Does anyone know if double hop uathentication using Kerberos is supported on Sql Server 2000. The linked server on Sql Server 2005 is created using this syntax
"EXEC sp_addlinkedserver @server=€™LinkedServer€™,
@srvproduct=''",
@provider='SQLNCLI',
@datasrc=€™SQLB€™,--the data source
@provstr="Integrated Security=SSPI; "
"exec sp_addlinkedsrvlogin €˜LinkedServer€™, 'true'"
SPN's and domain accounts have been created as documented and those same accounts are used in both the Sql Server 2005 and Sql Server 2000 instances.
The error message going from a Sql Server 2000 or 2005 client, to the Sql Server 2000 instance that has the linked server using the SQLNCLI provider is
Server: Msg 7399, Level 16, State 1, Line 1
OLE DB provider 'SQLNCLI' reported an error. Authentication failed.
[OLE/DB provider returned message: Communication link failure]
[OLE/DB provider returned message: Named Pipes Provider: No process is on the other end of the pipe.
]
[OLE/DB provider returned message: Login failed for user 'NT AUTHORITYANONYMOUS LOGON'.]
OLE DB error trace [OLE/DB Provider 'SQLNCLI' IDBInitialize::Initialize returned 0x80040e4d: Authentication failed.].
If I use the Sql Server 2000 OLEDB provider when creating the link I get this error
Server: Msg 18456, Level 14, State 1, Line 1
Login failed for user 'NT AUTHORITYANONYMOUS LOGON'.
The same link using the SQLNCLI provider in Sql Server 2005
works and I am able to use double hop authentication.
My question is , does anyone know if double hop authentication is supported using a Sql Server 2000 linked server?

I have created an Access2003 project (existing data) that links to external data. First I connected to a SQL Server 2000 database. Success. Then I tried to set up a Transact SQL data connection to a legacy MDW-secured Access97 database. (A third-party VB6 application goes against it, and we don't have the source code, so we cannot upgrade it.)
The Transact SQL link tests OK but I cannot select any of the tables or queries from the list presented. However, with the same credentials, I can use these same objects in Excel 2003.
When setting up the link in Access2003, I specify JET 4.0 OLE DB Provider, I enter the MDW file on the All tab, a username and a password on the Connection tab where I browse to the MDB file, and specify Shared Deny None on the Advanced tab. When I test the connection, it tests OK ("Test connection succeeded"). Yet on the "Select the Database and Table/Cube which contains the data you want" dialog, "(Default)" appears in the grayed-out dropdown. Then, beneath that dropdown, there is a grid with Name and Description columns. The grid contains query names but the grid is not enabled. The list of queries is this table is grayed out. Neither of the scrollbars works.
BUT... if I use the SAME username and password in Excel2003, and specify the same MDW, there is no problem working with these same database objects in the legacy Access97 database. WHAT IS DIFFERENT ABOUT THE WIZARD IN EXCEL THAT ALLOWS IT TO SUCCEED AND THE WIZARD IN ACCESS THAT CAUSES IT TO FAIL HERE? In Excel, the list of available providers says Microsoft Access Driver, not JET 4.0 OLE DB Provider.
Thanks

When trying to link to an SQL table in Access 2003, the software appears to be malfunctioning.
The sequence of events is File - Get External Data - Link Tables - Files of Type: ODBC Databases().
The Problem: On two of my computers, the select data source window does not pop up, preventing me from linking to any ODBC data source.
Observations: This function has worked normally in the recent past and works on other computers running Access 2003. One difference between the computers working and non-working computers is Norton Antivirus 2006 (recent upgrade).
Has anyone experienced anything like this? What's going on?

I have a report that was designed using SQL Reporting Services that sits on a SQL reporting server. It's nothing too exciting, it is essentially a three page application with legal jumbo on pages 2 and 3 and applicant data in fields on page 1.
We use rectangles to force page breaks to page 2 and to page 3.
When running the report on the report server, it shows and prints fine.
When running the report from the QA website internally, it shows and prints just fine.
When running the report from the production website from a machine internally, it shows and prints just fine.
When running the report from outside of the company network, the report is jacked. It obliterates large chunks of text, crams text together, and creates blank pages.
I need help in determining where I even begin with trouble shooting this!

can anyone tell me if they know of a way to automate the update process from development servers to live server, with little interference from an administrator
I have a development team that are constantly updating their databases along with their ASP code, and want to publish changes an a weekly basis. They have asked me for a way to take their new structures, tables, procedures etc, and copy them to the live servers, but NOT to interfere with existing customer data.
Funny I know – and I hate the idea btw :(
Any references, contacts, 3rd party tool recommendations welcome,
Thanx,
Darren

I am in the middle of a major migraton project, moving from x86 SQL 2000 to IA64 SQL 2005. I have a business need to link to several legacy servers. I have a number of problems I am trying to solve.
1) Linking a Kerberos server to a non-Kerberos server.
2) Linking x64 or IA64 servers to x86 servers.
3) Linking SQL 2005 to SQL 2000.
Two of the errors I am encountering are:
------------------------------
TCP Provider: An existing connection was forcibly closed by the remote host.
Login failed for user '(null)'. Reason: Not associated with a trusted SQL Server connection.
OLE DB provider "SQLNCLI" for linked server "SCDC250DB" returned message "Communication link failure".
(Microsoft SQL Server, Error: 10054)
------------------------------
And
------------------------------
The OLE DB provider "SQLNCLI" for the linked server "SCDC250DB" reported an error. Authentication failed.
Cannot initialize the data source object of OLE DB provider "SQLNCLI" for linked server "SCDC250DB".
OLE DB provider "SQLCLI" for linked server "SCDC250DB" returned message "Invalid authorization specification".
(Microsoft SQL Server, Error: 7399)
If someone has worked through these problems before, I would appreciate it if you could direct me to the relevant documentation to resolve these issues.
Thanks!

Hi all,I'd like to know what the best means available is to enable distributedqueries from a SQL Server 2000, on tables in BOTH SQL Server 2000 and aremote DB2 server (the latter is not yet available for testing).So, I would be wanting to write queries or SP's like:select t1.field1, t1.field5, t1.field6, t2.field55, t2.field22from MySQLServer.mydb.dbowner.tableXXX as t1inner join ThatDB2Server.thatdb.thatowner.tableYYY as t2 on t2.field11= t1.field99where t1.field44 = @foobarI'm aware of at least two ways to go here:1) in SQL Server 2000, create a linked server to the remote DB2server, either using the wizard or sp_addlinkedserver, and using eitheran OLEDB or ODBC connection;2) using MS Host Integration Server (HIS).Since I've only just today learnt about HIS, I don't know very muchabout it.Questions:(a) are options (1) and (2) mutually exclusive, or does one depend onthe other?(b) can I do (1) without having to bother with (2)? If this, wherewould I get hold of the required OLEDB/ODBC Provider?(c) Is there another way(s) to go about this task?HYCH,Rob

I have created a linked server using an userid that have access to 2 different databases. The linked
was created successfully but I am only able to see tables in 1 database but not both.
The tables of the databases that I can access is the default database of that userid. Is there a way to see all the
tables from more than 1 database that the user is authorized to? Thanks.

I am working from within an SQL database trying to get data from an MS Access Database as a linked server. I can "successfully" add the linked server, but when I try to open it from SQL EM I get "Error 7399. . . " from Microsoft Jet. When I try to query it from QA I get "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 tried both Access 2000 databases and '97. Same results for each. Big project pending . . . any help is appreciated!

I just reinstalled SQLExpress and all the dbs that I created are no more linked. The files still exist in the folder where the current version stores dbs (...Microsoft SQL ServerMSSQL.1MSSQLData) but they are not "linked" (don't know the right term).
Is there anybody who could help me how to "relink" these dbs to the actual .SQLExpress instance?
Thank you very much for any help!

I work extensively with Access; I have a new project with very large tables (as many as 15 million records). Is it worth my while to link Access to SQL Express if both are on the same machine?
I've downloaded SQL Express and installed it, but it won't let me link to Access 2003. Is there an update or patch to Access 2003 that will make this work?
If I do make the link successfully, will it be transparent - that is, can I work in Access as I always have, or would I have to learn how to create databases and queries in SQL? (I do know that I can make tables in Access and migrate them to SQL Server).
Where would I find simple step-by-step instructions to do this - my interest is more in the substance of my data analysis than in programming per se.

If I bring up a report in the report server (http://reportserver/Reports/Pages/.... and I set the parameters to see the information I want to see and say to myself, hey, my boss would really like to see this, how would I go about sending him the link to the report with the parameters already set. Ideally when I view the report, the parameters would show in the URL automatically as other reporting products do, however, SSRS does not provide this. I do not even see a function in the report designer to display the link on the report itself so I can cut and paste from it. Anyone know how to do this without having to custom craft a URL or set a one time subscription?
Thanks,

Does Microsoft plan to extend the number of Data Mining algorithms in AS in the future releases? The question is motivated by the task of so called "link analysis" where one should determine how data attributes are related to each other or how and in what extent they influence each other in probabilistic terms. A good solution would be to build a Bayesian Network which gives an insight to how data attributes are related by means of directed acyclic graph. But this approach is not yet implemented in AS2005.
Existing algorithms such as association rules or decision trees might be used but they are far from being ideal for this task (association rules are designed for determining frequent boolean sets in data like Name=Attribute, decision trees work good for classification tasks but perform poor by design for the tasks of revealing attributes direct and inderect influence).
It would be interesting to know what algorithms and approaches Microsoft plans to develop in the future.

Hi, not sure if this is the correct forum to post in?
I am trying to connect to a csv file to import into a table to process thru my vb.net coded application.
I see from BOL that I should not allow ad ho distributed queries and should create a linked server to the data I require.
I am trying to create a linked server to the csv file selected by the user but am coming unstuck as I do not know the correct info to put in the connection settings etc.
Code Snippet
Dim srvAdminServer As Server = Nothing
Dim cnSQLConnection As SqlClient.SqlConnection = New SqlClient.SqlConnection(My.Settings.MMConnectionString)
Dim scnServerConnection As ServerConnection = Nothing
Dim lsrv As LinkedServer
cnSQLConnection.Open()
scnServerConnection = New Microsoft.SqlServer.Management.Common.ServerConnection(cnSQLConnection)
srvAdminServer = New Server(scnServerConnection)
lsrv = New LinkedServer(srvAdminServer, "CSV-IMPORT")
lsrv.ProductName = "MSDASQL"
lsrv.Create()
The code above does not error until I call the create method when I get an unknown product or provider error?
This is all new to and I have searched and searched without success!
Can anyone help me?
Thanks
