Server to Server WCF failing as anonymous

Posted By:      Posted Date: September 03, 2010    Points: 0   Category :WCF
 
I have a winforms client that calls a wcf service that is hosted in IIS via https, this service then calls an internal WCF self-hosted service over net.tcp, this self-hosted service talks to the SQL Server. All was good in development while the external IIS service was on the same box as the internal self-hosted service. Once the external service was moved to a different server for testing the production environment things have bombed. The external IIS hosted service will not communicate successfully with the internal self-hosted service. The closest I can get is the error on the internal service that says "The service does not allow you to log on anonymously". I have tried configuring the identity for the app pool in IIS and setting the SPN for this domain account to no avail. Here are my configs:   Client: <system.serviceModel> <bindings> <wsHttpBinding> <binding name="WSSyncProvider" closeTimeout="00:10:00" openTimeout="00:10:00" receiveTimeout="00:10:00" sendTimeout="00:10:00" maxBufferPoolSize="2147483647" maxReceivedMessageSize="2147483647"> <readerQuotas maxDepth="2147483647" maxStringContentLength="2147483647" maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxNameTableCharCount="16384"/> <security m

SQL Server 2008 - Job Activity Monitor Failing

  
I recently began migrating to Windows 2008. One of the first servers is a server which we install our tools on. This is a new server which currently is only running the SQL Server management tools. On this server I installed the SQL Server 2008 R2 management tools, prior to this install there were no other SQL Server tools installed on this server. The majority of the functionality works and I can connect and manage multiple databases servers from SQL Server version 2000 through 2008. But when I try to bring up the Job Activity monitor I get an error ==> Can not show requested dialog. From Windows XP Windows Server 2003 SP2 this functionality works. I get this error if I connect to a SQL Server 2005 or 2008 database instance. I have tried re-installing the client tools but I still get this error..... any ideas?

SQL Server Network Interfaces Error 26 - while failing over SQL Server 2008 R2

  
Before I explain the issue I am facing, I would like to say that I did read the post at  http://blogs.msdn.com/b/sql_protocols/archive/2007/05/13/sql-network-interfaces-error-26-error-locating-server-instance-specified.aspx but in my case the problem is transient (lasts for approximately two minutes after a failover) so items 1-3 in the list of troubleshooting steps do not seem to make sense. As to 4 and 5, the named instances use non-default ports (2433 and 3433 respectively), so I do not know how to tailor the PortQry command for that. I tried  portqry.exe -n ServerA,2433-p UDP -e 1434 and  portqry.exe -n ServerA,2433 -p UDP -e 2434 and it failed both times with a "Failed to resolve name to IP address" while the server was up and serving database requests The same thing happened when I tried it with the failover server as well. ***The issue I am facing*** I am using Enterprise Library 4.1 to connect to a SQL Server 2008 R2 database with a mirror. My connection string itself is as below (with dummy values for all fields): "Data Source=ServerA;Failover Partner=ServerB;Initial Catalog=DBName;User ID=uid;Password=pwd;Connect Timeout=5" Sample .NET code is as below (with modifications to instantiate all variables locally to provide context): SqlDatabase db = new SqlDatabase(ConnectionString); SqlConnection cn = (SqlConnection)db

how do I enable anonymous search in search server express 2010

  
I am crawling a local file share that has read permissions for NT AUTHORITY\NETWORK SERVICE account. I have enabled anonymous access and now I am able to get to my search box without authentication. But when I actually search for something I get no results back. I am able to get results when using the administrator account. I have even created local account and that is also unable to see the results.

Failing Connection String Environmental Variable, XML Variable, System Variable (SQL Server) Setup

  

We attempted to implement the Chapter 2 Framework from the Knight, Vermeen, Moss, Hackney book on SSIS 2008: Problem Design Solution. We see a couple of problem areas (at least) in our interpretation of the guidelines from the book.

1. We are attempting to have one connection string per server: dev/prod

2. We have set up environmental variables per server: dev/prod

3. We have set up XML Package Variables per server: dev/prod

4. We have set up System Variables per server in SQL Server: dev/prod

Problem 1:

We've had to manually key in the common connection string to all packages on a server environment in the component properties area (control flow; not data flow--ok there)

Shouldn't the connection property find the connection that we've instantiated and provide us with a pull down to select it?

The components are un-editable after we select the common connection string, but they still run properly in our SQL Server Agent Job.

Problem 2:

The dev server variable overlays the prod server variable information duringprod component editing

We are'nt sure if these problems are related.

Here is our package variable:

\Package.Variables[User::connMedcDwProd].Properties[Value]

 

Here is our DTSconfig file; we have a few variations of this that we've tried.


Server out of memory error in a LIST (anonymous site) that has eventhandlers

  

Scenario: We have a sharepoint site on wss 3.0 set to anonymous access. It has couple of lists and the pages render fine to any user. The moment I associated eventhandler to a list, started getting 'server out of memory'. Removing eventhandlers works fine but without eventhandlers I can't write business logic.

Searched so far and found that people have suggested to use guest account or some other account. Still looking into this so far.

Does anyone has better resolutions? Has Microsoft released any solution / hofix so far? 

thanks.


SQL Server Mobile 2005 Merge replication failing over SSL, but can browse through pocket IE.

  

Hi All, this system is scheduled to go live in near to a day... but i have hit an issue when switching on SSL.  Any help would be greatly appreciated.

 

Device Env:

Windows Mobile 5.0 + Messaging and Security Feature Pack

SQL Server Mobile 2005.

 

Merge replication works fine without SSL.  After running the Configure Web Sync wizzard to setup SSL merge replication no longer works.  Note i checked using pocket IE by browsing to https://mycompany.com/pub/sqlcesa30.dll?diag and all worked fine.  There was no prompt saying the cert was bad etc.

 

The certificate is a:

Equifax secure global ebusiness CA-1 cert.

Signature algorithm md5RSA

public key RSA(1024 bits)

thumbprint algorithm sha1

 

Stacktrace given is:

-  ex {"A request to send data to the computer running IIS has failed. For more information, see HRESULT."} System.Data.SqlServerCe.SqlCeException

Linked server fails -Login failed for user 'NT AUTHORITY\ANONYMOUS LOGON'. with SQL2008R2

  

Hi, Kerberos seems to be malfunctioning with SQL2008R2.

 

I have a new dev SQL2008R2 server called BDSDEV2 and an upgraded(in-place) SQL2008R2 server BDSTEST2.

From BDSDEV2 , I can successfully issue a linked server query to BDSTEST2

select * from bdstest2.eis_prod.dbo.wcs_agent

 

But from my client in SSMS, connected to BDSDEV2  , the double hop is failing to BDSTEST2 for same query 

Login failed for user 'NT AUTHORITY\ANONYMOUS LOGON'.

 

I have another BDSDEV1 server, which is SQL2008 and there double hop IS WORKING

From my client in SSMS, connected to BDSDEV1  ,I can successfully issue the query to BDSTEST2 .

 

The service accounts  for MSSQLSERVER are both local admins on their servers and sa's

I have confirmed SPN is OK 

This is from BDSDEV2 - sql2008r2 server.

Sql Server 2008 import and export wizard is failing

  

Sql Server 2008 import and export wizard is failing with the message: \

 

The ‘DbProviderFactories’ section can only appear once per config file. (System.Configuration)

This wizard will close because it encountered the following error: (Microsoft SQL Server)

 

This happens when I hit the “Next” button on the initial import/export wizard startup screen.

 

The detailed error message is below.  Any ideas on the location of the configuration file that the change needs to be made to?   

call JavaScript - jQuery code from ASP.NET Server-Side

  
jQuery got so close to me lately that I can see myself adding the scripts to my project almost unconsciously. The thing is, jQuery is very useful for me, in almost all situations and it has been a do or die enhancement for all my project since I first put my hands on it.

Of course while using it, you encounter few situations which need a bit of research to solve, mostly when you are trying to combine it with some other technologies like: UpdatePanels and ASP.NET Ajax. For instance there are many situations when I would like to run some jQuery magic based on some decision that I make on the server side.

Making Ajax Callbacks to the Server Using jQuery with ASP.NET

  
In the first part of this article series I introduced jQuery's functionality and how it provides a rich client side programming model. This time around I'll expand on these concepts and show you how you can use jQuery in combination with ASP.NET using it as an AJAX backend to retrieve data. I'll also discuss how you can create ASP.NET controls and otherwise interact with jQuery content from ASP.NET pages in WebForms.


jQuery is just a JavaScript library so it will work seamlessly with ASP.NET both from page code as well as through backend driven code using the Page.ClientScript object or ScriptManager. You can use jQuery on its own as a client side and Ajax library that communicates with ASP.NET or you can use jQuery in combination with ASP.NET AJAX. The two actually complement each other quite well as jQuery provides functionality that the ASP.NET AJAX library does not and vice versa. For the most part the interaction between the two libraries is trouble free except for a few very rare edge cases.

MS SQL Server: Disconnect Users From Database - Kill User Session

  
If you ever wanted to restore your database from a SQL backup file (.bak), but there are still users connected to your database, the backup operation will fail causing the error: Exclusive access could not be obtained because the database is in use.

MS SQL Server: Search All Tables, Columns & Rows For Data or Keyword Query

  
If you need to search your entire database for specific data, this query will come in handy.

So when a client needs a custom report or some sort of custom development using Great Plains, most of the time I will have to track down the data in the system by running this query and find the table(s) it is in.
