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.

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".

Security Account Delegation

Oct 22, 2006

Hi world,

I have a question, but first I need to give you some background:

My network works with Active Directory on Windows 2000, and I have web servers running on windows 2003 and SQL Servers 2000 running on Windows 2003.

I wanted to enable account delegation and I found a bunch of information.

Everything seemed "easy", but I tried to test it first on my test servers anyways and this is what happened:

We created the SPN for the SQL Server
Account is trusted for delegation check box was selected for the service account of SQL Server.
Account is sensitive and cannot be delegated check box was not selected for the user requesting delegation.
But when we checked the box Computer is trusted for delegation (and only this box !!) in the server running an instance of SQL Server 2000, the role of this server changed magically (just like this guys, it was magic) from "server" to "Domain Controller".

We were intrigued about this change, but we "trusted" the white paper that we had in front of us.

http://support.microsoft.com/kb/319723

After some hours, the production web servers (of the whole network) and many workstations stopped working:

The IIS on this web servers will show an empty list of websites
The network and dial-up connections were missing on the web servers and also on the workstations.
The web servers and the workstations affected were "isolated" from the network, the command ping was not finding any of this computers.

Anyway, it was a nightmare, it took a while to fix the mess, we reverted the changes in Active Directory, and this makes me thing that the magical "promotion" of the SQL server to Domain Controller had to do with all this.

the questions is:

Do you have an idea about what could have caused all this? I mean, I still need to enable this account delegation thing. But I would like to know first if someone has done it before in a similar environment or if someone has run into one of the problems described before.

Thanks world.

Constrained Delegation For SSRS

Sep 4, 2007

I am having a problem implementing constrained delegation for SSRS. I have followed the (very good) instructions located here:
http://sqlblogcasts.com/blogs/stevechowles/archive/2007/06/08/reporting-services-2005-for-the-dba-iis-security.aspx

I have chosen the option of running the application pool for SSRS under a domain user account. This is the same account that I use to run the SSRS service.

I have the authentication providers for the site set to "Negotiate,NTLM".

I also made sure that the application pool user account has rights on the ReportManager and ReportServer directories.

If browse to the URL while logged on to the SSRS server then I am able to access the site
My problem is when I try to access the site from anywhere but locally on the SSRS server:

I get a logon prompt if I try to access the SSRS URL from a different workstation. After three tries to login I get: "You are not authorized to view this page". Even with an account that is local admin on the SSRS Server.
If I set the authentication providers for the site to "NTLM" then I am able to access the site from a different workstation but of couse constrained delegation does not work.
Have i overlooked something? What could be causing the login prompt?

Kerberos Delegation Don't Work With SSIS ?

Aug 10, 2007

Hello,

I have configured Kerberos delegation for several web services. One of the web service calls SSIS packages, but the packages don't run with the expected impersonate user : the package starts with the imporsonate user, but continue with ASPNET user (which is not allowed to execute SSIS and connect to DB).

If the web service is called directly (no delegation), SSIS packages run with the correct user. It looks like than there is an autenthicate issue, but kerberos is configured and web services can run from one to another with the impersonate user. The issue occured only when I call SSIS packages.

Here is a extract of the SSIS log file :

Code Snippet <dtslog>

Accessing Network Shares Using Impersonation And Configuring Delegation

Oct 29, 2007

I'm having trouble trying to access a network share that comes via a UNIX server running SAMBA. In the first case, I'm running on my local workstation (A), connected to a remote server (B), and attempting to access directory information for a path like:

\a0amsimmsworkseaborg argets11as2981

This path is fully accessible by me from the workstation (A) and the server (B). The files and directories below "work" in the above path are also wide open on the UNIX side (meaning r-xr-xrwx permissions). However, if I attempt to do something like this:

Code Block
WindowsIdentity newID = SqlContext.WindowsIdentity;
WindowsImpersonationContext impersonatedUser = newID.Impersonate();
bool sim_dir_exists = false;

try
{
impusername = Environment.UserName;

Directory.GetFiles(mdcfullpath);
}
catch (Exception e)
{
impersonatedUser.Undo();
SqlContext.Pipe.Send("Exception getting data: " + e.ToString());
SqlContext.Pipe.Send("CWD is: " + Directory.GetCurrentDirectory());
SqlContext.Pipe.Send("User is: " + impusername);
}
finally
{
impersonatedUser.Undo();
}

The "GetFiles" fails with the following exception:

Exception getting data: System.UnauthorizedAccessException: Access to the path '\a0amsimmsworkseaborg argets11as2981' is denied.

at System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath)

at System.IO.Directory.InternalGetFileDirectoryNames(String path, String userPathOriginal, String searchPattern, Boolean includeFiles, Boolean includeDirs, SearchOption searchOption)

at System.IO.Directory.GetFiles(String path, String searchPattern, SearchOption searchOption)

at System.IO.Directory.GetFiles(String path)

at StoredProcedures.mdcinfo(Int32 sim_id, String mdc_base)

CWD is: C:WINDOWSsystem32

User is: amsimms

Initial is: dbserver

Interestingly, if I run the procedure directly on the server (B), I do not get the exception. So this seems to be more of a delegation problem. The server B's sql server instance is running as a domain account (dbserver), which has been enabled for delegation and an spn has been set up. Is there something beyond this either with the impersonate or delegation configuration that I need to do in order for this to work?

Thanks,

--Andrew

SQL Agent Delegation Errors After Upgrading To Build 3186 On MS Cluster

Sep 12, 2007

Hi,

I've just installed SQL 2005 SP2 Rollup 3 Package (Build 3186) on a 2 node X64 W2K3 Cluster.
Everything went fine, although after the install, the SQLAgent Services of my instances started to complain about delegation not enabled for the domain account used for the SQLAgent Service.

SPN's were already registered, so I've enabled unconstrained delegation & no errors anymore..

Apparently we're obliged to enable delegation as soon as this hotfix is installed

(maybe due to fix 938086 included in it ?)

To make this setup more secure, we would like to enable constrained delegation.
This does not seem to work, as soon as we choose constrained delegation by adding the SPN of the clustername to the domain user account we're running with & restart the sql agent, it fails with the same error as when no delegation was configured:

! [298] SQLServer Error: 22022, CryptUnprotectData() returned error -2146892987, 'The requested operation cannot be completed. The computer must be trusted for delegation and the current user account must be configured to allow delegation.' [SQLSTATE 42000]
! [442] ConnConnectAndSetCryptoForXpstar failed (0).

Summary:
With Unconstrained delegation enabled for computer account & user account, everything goes fine.
As soon as constrained delegation is chosen, by adding the SPN's to the domain user account of SQL Agent, SQL agent fails to start.

We use a domain account for the SQL Agent.
This account has an 2 SPN registered on it

MSSQLSvc/<FQDN SQL instance network name>:1433
MSSQLSvc/<FQDN SQL instance network name>

Connections to SQL go fine, authorization scheme is Kerberos even when SQL Agent fails to start due to this delegation failure.

Domain account has "act as part of operating system" & "impersonate a client after authorzation"

Anyone an idea ?

User Credentials Delegation From IIS On WinXP To SQL Server On Win2003SRV Fails

Jan 12, 2007

Problem:

I am trying to create an asp.net website with integrated windows authentication
to access SQL databases. IIS resides on WinXP and SQL Server
on Win2000 SRV. Both are in the same NT Domain. IIS and SQL Server cannot
reside on the same machine and a stand alone web server is
ideal as the website needs to access multiple SQL Servers. IIS is set to
Integrated Windows Authentication. The machine running IIS & the SQL Server
are set to be "trusted for delegation" in active directory. The domain user
accounts that will be accessing the databases are not marked as "Account
is sensitive and cannot be delegated".

The connection string that the web app uses to connect to SQL database is:

"Data Source=PWSSQLT;Integrated Security=SSPI;Initial Catalog=Pace_Master;Persist Security Info=true"

with which the user credentials should be flown to the SQL database.
But instead the delegation fails and results in the following ANONYMOUS authentication failure error:

Login failed for user 'NT AUTHORITYANONYMOUS LOGON'.

Description: An unhandled exception occurred during the execution of the current web request.
Please review the stack trace for more information about the error and where it originated in the code.

Access2003 Cannot Link (but Excel2003 Can Link) To Tables In Access97 Database

Feb 20, 2008

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
TR

Cannot Link To SQL Tables Using ODBC Link Table In Access 2003

Feb 3, 2006

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?

Sql Report Works Fine On Internal Servers - Hosed On External Servers - Need Some Help

Nov 21, 2007

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.

Linking SQL 2005 Servers To SQL 2000 Servers Problems

Sep 27, 2007

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!

Link To DB2

Jan 21, 2006

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

Is there anybody who could help me how to "relink" these dbs to the actual .SQLExpress instance?

Link To Access

Jul 31, 2007

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.
