Our topology:
Internal corporate network domain utilizing Integrated Windows Authentication between local workstations and the web and database servers. (domain similiar to: http://reports.ourdomain.com)
Machine #1: Windows 2003 Server w/SQL Server 2005 (SP2 and hotfixes applied) running SSRS.
Machine #2: Windows 2003 Server w/SSRS only. (pointing to the SQL DB on Machine #1)
Machine #3: Windows 2003 Server w/SSRS only. (pointing to the SQL DB on Machine #1)
Device #1: Arrowpoint load balancer for Machines #2 & #3 (w/sticky sessions).
We recently added 2 web servers and configured them to load balance the web requests to a seperate SQL Server machine. (the load balancing is done thru an Arrowpoint device not Microsoft NLB)
The installation of reporting services (on Machine #2 & #3) went smoothly and the configuration was a breeze. But we could not access the "http://reports.ourdomain.com/Reports" directory for reporting services on the 2 web server machines. We received the "401.1 - Unauthorized" http error.
Since we were using a domain name to access the report server we made sure to update the <URL> tag in the config files.
We still received the error, so then we added a couple of entries to the HOSTS file on each web server:
File location -->
C:WINDOWSsystem32driversetcHOSTS
In order for the load balancers to "see" themselves from the domain reference we had to update the HOSTS file
on each web server to have the domain name "reports.ourdomain.com" point to the IP Address of the specific web server.
(we also added the IP of Machine #1 just to be safe):
Then the web servers were able to authenticate the users using IWA and NTLM
and we could access the report servers normally. Even the the scheduled reports
were being load balanced and emailed from the web servers which we didn't
expect to happen. (pretty cool!)
I hope this helps someone else as it tooks us about 4 days to figure this out.
Hi everyone, Anyone know how SQLDependency works in a web farm setup? Which machine will receive the notification - All of them or just the machine that started the dependency?Marc
I am developing a web app that uses a SQL Server backend and will be served by a Web Farm at some point in the future. Can anyone give me some guidance at to what the common architectual considerations are when using SQL Server with a Web Farm? Initially, would it be allright to continue to have a single SQL Server on the network, with several webservers connecting to it instead of just one, or would this be a big performance nightmare? Eventually, since the goal of using the Web Farm would be to reduce individual server load, I would think having multiple SQL server instances would be preferred. Is this even done in the real world? I'm not a dba, so I'm not quite sure of the how multiple instances would be synchronized so that they held the same data and how applications on varying web servers would know to connect to one or another (by varying the connections string, perhaps). Can anyone give me any guidance? Thanks!
I have to install several AG on a cluster for a whole SharePoint production farm, it's a nice to have (1 AG for Search database, 1 AG for Profil database, 1 AG for Content database, 1 for applicatif, etc...) We have 2 Front End load balanced, 1 application server and 3 SQL HADR: 2 nodes on synchrone (sql 2014 enterprise licence) and the 3rd asynchrone (standard licence).
The SharePoint farm is configured with the SQL Alias on the primary node, then if there is a failover on node 1, I must move the sql Alias to the second node manualy, unless I'd configured this Alias to point on the AG listener of the availability group in order to use the automatic failover. But as we have several AG, should I create one listener per each AG?
And which AG listener should I have to configure on the SQL Alias then ?
Dear, I have designed a SiteMap provider for SQL Server. But I am worried about the notification service of SQL Server. My SiteMap requires service broker enabled in SQL Server. When I have web farm (multiple clustered server) does the Sql Server service broker notify all the web servers? Or, it notifies only the server request? Have anubody implement such scenario? Looking forward for your reply. Sincere Regards,Sultan
I have implemented SQL cache dependency to invalidate cache whenever the result of the stored procedure gets changed. The stored procedure is written obeying all the notification rules. Our problem: As long as we are working on Local machine, Development server or Pre production server its working fine means the cache gets invalidated whenever there is any change in the result set. But the same implementation doesn’t work in Production. Cache does not get invalidated. Difference in Production environment and other environment: Production uses cluster SQL server, others use standard SQL server. Production has load balancing means application is deployed on 6 servers which hits same clustered SQL server. In application’s global.asax file i have Start dependency so I see 6 different notifications started in SQL server which is right. But whenever there is a change in result set the cache doesn’t get invalidated in any of the application. My question is Do we have to follow any different kind of implementation of SQL cache dependency for web farm and cluster SQL server scenario? On the same note I would like to add, on the same SQL server I have one more database and a different application is accessing this database. This application is also using SQL cache dependency and its working fine. The only thing this .Net application is NOT deployed on web farm. Its deployed on single application server.
In our current project, we are attempting to use Broker for the middleware for a "queuing" solution that helps in throttling & load-balancing incoming messages. These messages could potentially be either long-running jobs or simply an incoming flood of messages received from our integration web services that are called upon via BizTalk.
For the posting of messages onto the "to do" queue, we are implementing the "fire & forget" pattern that has been discussed here previously and on Remus' blog. This aspect of the design seems to work fine for us. Currently we have this setup where activation is occuring on the target queue, but we don't want to hold open a thread there on the server while waiting for our synchronous calls to various web-services on the processing "farm" to complete.
The next evolution of our design is to try and move activation from off of the primary SQL cluster itself (i.e. activation is currently happening on the clustered SQL boxes) onto the individual processing nodes. For this model, we are looking at using SQL Express on each of the nodes as has been suggested here on the forums for other similar scenarios.
For resiliance to any node failures, we do not want to "route" the messages to the individual nodes hosting their own queues but rather have those nodes do a "read" from the primary queue and do the per-message processing and performing either a committed EndDialog of EndDialogWithError based on the success of processing each task/message.
To invoke the processing on each of the nodes, we need some form of mechanism to send a "wake up" and do the "reads" since no message is being sent to the node itself for any form of activation based on a queue that receives the actual "job". On the same hand, we are considering having a "wake up" queue on the nodes where a simple "wake up" message could be sent to all nodes/queues and then activation on those queues would then invoke the processing "loop" for each node.
My question is how to best establish this "wake up" call to each node. I think I've read about a queue that is internal to Broker itself that receives a message when new items are received in any queue. My initial thought is to put activation on that queue and have a procedure that sends the "wake up" to each of the nodes in our processing farm.
I am looking for any input where others have attempted to solve this type of problem with Broker.
I am trying to create a scale-out deployment of Reporting Services 2005 on a NLB cluster web farm by following the instructions in: http://technet.microsoft.com/en-us/library/ms159114.aspx
However, when I install and configure Reporting Services on the second node, and then go back to the first node to join the second node to the scale-out deployment (as described in step 11 under 'To install and configure the second report server instance"), I get the following exception:
ReportServicesConfigUI.WMIProvider.WMIProviderException: An unexpected error has occurred. Details:
The RPC server is unavailable. (Exception from HRESULT: 0x800706BA) ---

I have spent hours searching for ideas, but so far no success. I have also tried the following:
1. Enabling DTC access 2. Ensuring RPC service is running on both web and db servers 3. Installing WMI Windows Installer Provider 4. Granting admin rights on both db and web servers to the account under which Reporting Services is running
Any help or suggestions would be greatly appreciated. It looks like this should be a straight-forward task.
We are using RS2005 for a year now and never had any problems especially with mail subscriptions.
Since we transferred from single RS machine to web farm everything works ok except mail subscriptions. Subscription sometimes (?!?!?!?!) refuse to export report to a document of any kind. I repeat that this is a random thing which is more often with PDF and less with Web Archive or Excel. We are using shared schedules and on demand execution of AddEvent stored procedure by night batches to send mail to users. Also, original error from RS log says something that this kind of operation is not supported for server working in native mode. We don't have SharePoint so we never used it in any other way then native mode and it worked.
Any idea will be appreciated!
Thanks in advance.
Update 26.06.2007
It seems that problem is not loading dll used to export report to a file but loading email subscription extension (dll that needs to be loaded for execution of email subscription.)
Original error from RS Log:

I am using mixed security on the SQL server and have an NT group 'NT_GROUP'. The login for 'NT_GROUP' has been added to SQL server and has been explicitly granted access to only one database.
Using access database project (ADP), a user in the group is able to gain access to other databases (master, tempdb, msdb, etc.) as well.
It is very important to be able to prevent this access.
Other postings I know have asked about this error message, but none has quite been my particular experience.
Using Visual Studio 2005 I have developed an aspx (.NET 2.0) web page, which has embedded in it, a Report Viewer object. Clicking a button calls the Reporting Services report and populates the Report Viewer object. This web-page works fine when run from Visual Studio.
Once deployed to the Web Server however, the web page produces the 401 error message.
I can also run the report fine, when running it directly from the Reporting Services Report Manager, so I know I have the proper permissions on RS itself - it fails only when I try calling the report from the ASP page.
First off, I know little to nothing about SQL. I run the IIS web server and the programmers run the SQL server. Recently the programmers found a backup running everynight at midnight and its messing up the Differential backups. By that I mean, since the full backup runs, the differential isnt backing anything up since it is set to only backup from the last full backup.
The backup seems to be backing up to a "Virtual Device" and I have no idea what that is. I am unable to see any user associated with the backup and I'm at a total loss as to where the data is going. Can someone please help me resolve this issue. I searched but was unable to find anything as I have no idea what to search for to find where this backup is coming from.
Here is a log from said backup...
Database backed up. Database: dbname, creation date(time): 2008/03/10(03:40:58), pages dumped: 1, first LSN: 288:523:56, last LSN: 288:547:1, number of dump devices: 1, device information: (FILE=1, TYPE=VIRTUAL_DEVICE: {'{B9A0EFAB-8894-4BBC-BC77-82DA1B58E2D4}28'}). This is an informational message only. No user action is required.
Lastly... The programmers do have backups running.. full once a week and differentials inbetween. the problem is, those logs look like this...
Log was backed up. Database: dbname, creation date(time): 2008/04/09(03:32:53), first LSN: 135:305:1, last LSN: 135:305:1, number of dump devices: 1, device information: (FILE=1, TYPE=DISK: {'D:ackup imeanddate.BAK'}). This is an informational message only. No user action is required.
I am getting the mentioned error: The request failed with HTTP status 401: Unauthorized, when i tried to call ReportingService2005 reference in my IIS web project.
Below is my code:
string strReport;
string strRptUrl;
string strFormat;
string strFormatCode;
ReportingService2005 rs = new ReportingService2005();
// Pass Windows Authentication credentials to Web Service
I have deployed the reports to the report server(centralized server). when i try to access the reports directly thru report server i.e http://servername//ReportServer in my local system. it asks for the username/password, when i give the username and password it accepts and shows me the report.
the same report i try to access in .NET Application, i do not know how to pass the credentials and it throws the error :"The request failed with HTTP status 401: Unauthorized ".
I am using VS 2005 and SQL Server 2005 and SQL Reporting Services 2005.
Hi, can anyone help with this pls - it's getting very fustrating! there seems to be some messages and text on this issue (looks like a common problem that MS haven't published anything about yet!) but nothing I could make heads or tails off... so any help here would be very useful!
I'm using VS2005 (release, NOT beta), the new reportviewer web control and an ASP.NET page - really basic, nothing fancy. I've set the reportviewer properties to:
I'm testing the ASP.NET page is on my local machine - and the reportviewer is connecting to a remote test server (W2k3 SP1). When I view the page, then I get
HTTP ERROR 401 Unauthorized
Directory Security on the report server is Windows Authentication - W2K3 with SP1 and Reporting Services 2005 (release, NOT beta)
Directory Security on my local machine is Windows Authentication - XP SP2 and VS2005 (release, NOT beta)
I am using report viewer in my asp.net application When i try to access the reportserver page in my application i get this error The request failed with HTTP status 401: Unauthorized
My webserver and the Sql server are in different computers.. The Report Server is been installed in the Webserver but in the database set up its talking to the sql server computer.. I have tried giving credentials in the webconfig file but i get the above error..
Here I will describe my problem. 1. We are loading large amount of data from database on background thread which is starting on Application_start event in global.aspx.cs file.The data is later cached for subsquent request to improve the performance. 2. Now when we put the application on web farm garden, it is not able to load the application. 3. We are sending the request the servers through Router kind of application. 4 This application is working fine on single server enviornment.
I'm attempting to setup the defaco MS security for membership and roles, using a newly created database under SQL 2005 (not express). I created the database using the aspnet_regsql.exe utility and that worked fine. I created my provider connection string logging in as 'sa' wit the proper password. All that seemed to work okay too. However when I attempt to change any of the settings like setting the authentication type or enabling roles, I get the follwing error message: The following message may help in diagnosing the problem: Attempted to perform an unauthorized operation. at System.Security.AccessControl.Win32.SetSecurityInfo(ResourceType type, String name, SafeHandle handle, SecurityInfos securityInformation, SecurityIdentifier owner, SecurityIdentifier group, GenericAcl sacl, GenericAcl dacl) at System.Security.AccessControl.NativeObjectSecurity.Persist(String name, SafeHandle handle, AccessControlSections includeSections, Object exceptionContext) at System.Security.AccessControl.NativeObjectSecurity.Persist(String name, AccessControlSections includeSections) at System.Security.AccessControl.FileSystemSecurity.Persist(String fullPath) at System.IO.File.SetAccessControl(String path, FileSecurity fileSecurity) at System.Configuration.Internal.WriteFileContext.DuplicateTemplateAttributes(String source, String destination) at System.Configuration.Internal.WriteFileContext.DuplicateFileAttributes(String source, String destination) at System.Configuration.Internal.WriteFileContext.Complete(String filename, Boolean success) at System.Configuration.Internal.InternalConfigHost.StaticWriteCompleted(String streamName, Boolean success, Object writeContext, Boolean assertPermissions) at System.Configuration.Internal.InternalConfigHost.System.Configuration.Internal.IInternalConfigHost.WriteCompleted(String streamName, Boolean success, Object writeContext, Boolean assertPermissions) at System.Configuration.Internal.InternalConfigHost.System.Configuration.Internal.IInternalConfigHost.WriteCompleted(String streamName, Boolean success, Object writeContext) at System.Configuration.Internal.DelegatingConfigHost.WriteCompleted(String streamName, Boolean success, Object writeContext) at System.Configuration.UpdateConfigHost.WriteCompleted(String streamName, Boolean success, Object writeContext) at System.Configuration.MgmtConfigurationRecord.SaveAs(String filename, ConfigurationSaveMode saveMode, Boolean forceUpdateAll) at System.Configuration.Configuration.SaveAsImpl(String filename, ConfigurationSaveMode saveMode, Boolean forceSaveAll) at System.Configuration.Configuration.Save(ConfigurationSaveMode saveMode) at System.Web.Administration.WebAdminPage.SaveConfig(Configuration config) at ASP.security_setupauthentication_aspx.UpdateAndReturnToPreviousPage(Object sender, EventArgs e) at System.Web.UI.WebControls.Button.OnClick(EventArgs e) at System.Web.UI.WebControls.Button.RaisePostBackEvent(String eventArgument) at System.Web.UI.WebControls.Button.System.Web.UI.IPostBackEventHandler.RaisePostBackEvent(String eventArgument) at System.Web.UI.Page.RaisePostBackEvent(IPostBackEventHandler sourceControl, String eventArgument) at System.Web.UI.Page.RaisePostBackEvent(NameValueCollection postData) at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)Anyone have any clue why this is happening?

I'm pretty stuck on a security issue in SSIS. The web service works by itself, but I can't call it from SSIS, it gives me a 401 unauthorized error. The web service also uses impersonation of my domain admin account.
I have tried the following things: Setting integrated windows authentication in IIS Setting the NTFS permissions of those web site directories to EVERYONE Using a credential / proxy in SSIS and running it from SQL Agent Changing the log on services of MSSQLSERVER, SQLAGENT, and SQL Integration Services to my domain admin account
I can't get anything to work. What is wrong with this thing? Microsoft's security model has gotten completley out of of hand imo
Also in the security event log it shows all authentication as successful.
I have programmatically deploy SQL server Reporting Services 2005 reports via msi file. The installation was success, I was able to run the reports on localhostReports at the target machine. But I get error "The request failed with HTTP status 401: Unauthorized." when I try to access it from the ASP.NET app report menu in the target machine.
It is Windows Server 2003 standard edition, it uses Windows Authentication. I have tried setting any combination below and still doesn't work. Anybody has any other ideas?
ReportingService2005 rs = new ReportingService2005();
rs.UseDefaultCredentials = true; rs.PreAuthenticate = true; rs.Credentials = System.Net.CredentialCache.DefaultCredentials; or rs.Credentials = new System.Net.NetworkCredential("Admin", "psw");
I receive the following error when i call report server web service from an asp.net application:
"The request failed with HTTP status 401: Unauthorized."
Here are the IIS logs on the reporting services server. When i open IE and browse to the web service i provide my user credentials and i can access the web service just fine. However when i call the web service via my asp.net application it looks like my credentials are not being passed??
I'm trying to install SQL Server 2008 on a virtual machine with Windows 2008 R2. Setup fails with the error "Attempted to perform an unauthorized operation". Looking at the installation log, I see these details:
We are in the process of setting up a test server for reporting services in which the reporting server is on a seperate IIS server as the SQL Database. I was able to resolve a previous error I was receiving when connecting to reporting services using SQL server management studio and within SQL Surface Area Configuration (HTTP Status 404: Not Found. ((Microsoft.SqlServer.Management.UI.RSClient)) by editing the URLRoot in the rsreportserver.config file. But now whenever we try to connect using SQL Management Tool from other than on the server we receive this new error:
TITLE: Connect to Server ------------------------------

We have built a .NET on SQL Server application with extensive business functionality and security. It uses SQL integrated security to control logon and access to the database objects. There is business logic built into the .NET code, so I don€™t want any chance that users access the tables directly through a tool such as Management Studio - many users need update, delete, insert on tables in order to use the applications functions. With integrated security they can logon through SQL Management Studio and change data in the tables directly.
How are people who are using integrated security for their business applications preventing logons through unauthorized tools or applications?
I have been trying to develop an automatic way of programmatically accessing datasources and performing some predefined(-supported) processing on them.
The question I would like to ask you people has to do with numeric fields. What exactly is precision? Is it the maximum length in digits of a field, or is there more to it? What about a "field's scale", what is it and how does it affect a field's value handling?
Can you have different scales on a bar chart. I want to chart sales and quantity. Oracle lets you label the top of the bar chart as money and the bottom as quantity.
I am dividing my sales by one million and quantity by one thousand to make them similar in size on the same chart. I am using the sum of the sales/1000000 as a point label. Is there any way to limit the number of decimal places displayed. Currently it is displaying something like 1.94889312043; 1.95M would be better.
