Hi,

I've created a small website with a simple sqlite database using vwd 2010 .net 4. In dev and test envionments everything works fine, however when i promote to my hosting provider i receive the following error:

A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)

I've been configuring the connection strings (autogenerated from entity framework and attached db) but unable to get it working on the hosting provider, I'm assuming it's related to permissions but not entirely sure how to resolve - here's the web.config as it stands:

<add name

I installed a new installation of SQL 2008R2 server on Windows 2008R2 server. First I can not connect to it with SQL management Studio 2005 so I wanted to install 2008R2 and I can not install it and that first. I used a PC with SQL management Studio 2008R2 but I can not connect to the database and I receive the following error "a network-related or instance-specific error occurred while establishing a connection to sql server, the server was not found or was not accessible. Verfiy the instance name is correct and that SQL server is configured to allow remote connection. error 40 - could not open a connection to SQL server Microsoft SQL server, error 2

A network-related or instance-specific error occurred while establishing a connection to SQL Server.

  

I have looked all over and tried every suggestion to resolve this issue but it persists:

I am trying to connect to an sql server on a windows 7 machine from an asp.net application.  When I am in Visual Studio I can use the connection in sqldatasource controls and everything is fine when I test the queries.  However, when I attempt to run the application I get the error.

I've tried:

1) Turning on named pipes on the database server and restarting the server.

2) Stopping all firewalls on the server.

3) Making sure that the server is configured to allow remote connections.

My connectionstring is:

Data Source=MYSERVERNAME\mssqlserver;Initial Catalog=NEMO;User ID=sa;Password=password

I have tried using portqryv2 to see whats happening on the UDP port that sql server uses as suggested in another post but gets a syntax error from the utility.

I am baffled by this one and would greatly appreciate some help.

Thanks.

"An error occurred while retrieving data from Oracle Instance..."

  

I have succeffuly Imported the ADF and have also successfully created a Business Data Column. But when I try to query data , I get the following error

An error occurred while retrieving data from Oracle Instance. Administrator, see the server log for more information

And this is what I found in the Application Logs
A Metadata Exception was constructed in App Domain '/LM/W3SVC/81256521/ROOT-1-129217212004078822'. The full exception text is: LobSystem could not be found using criteria 'id=476'.


System.Net.WebException: The underlying connection was closed: An unexpected error occurred on a rec

  
Hello Guys,         I am getting following exception while web service (ASMX) is returning the response. <!-- [if gte mso 10]> <mce:style> System.Net.WebException: The underlying connection was closed: An unexpected error occurred on a receive.     <!-- [if gte mso 10]> <mce:style>                                                     InnterException (System.IO.Exception): "Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host."       I think either the Asp.net web server is closing the connection or the response is too long.   Following is my simple code.    1)   namespace JFA.IndiePay.BusinessAccess { public class VerTexProcessor { public DataSet ProcessVerTexForBatch(DataSet dsInputRequest) { DataSet dsResponse = new DataSet(); //Call vertex web service here.

WCF Tracing Error: An operation was attempted on a nonexistent network connection

  
I setup WCF service tracing because 1 client out of about 30 wasn't able to finish the connection to the server. After setting up test case on that client, the WCF trace report gave me these exceptions:     An operation was attempted on a nonexistent network connection and then     The I/O operation has been aborted because of either a thread exit or an application request I found this MSDN question and solution that applies to Windows 2000 Server and Terminal Services and offers a hotfix to fix the issue. I'm using Windows 2003 Server, so the hotfix doesn't apply to me. Does anyone know what is happening to this 1 client while the other 29 connect just fine? The client returns this exception when trying to open the connection to the server:     An error occurred while receiving the HTTP response to http://endpointaddress/. This could be due to the service endpoint binding not using the HTTP protocol. This could also be due to an HTTP request context being aborted by the server (possibly due to the service shutting down). See server logs for more details.

The underlying connection was closed: An unexpected error occurred on a receive

  
Hi All,   i have developed a web application to call WCF service (which is hosted in IIS) from client application using .Net 1.1 it works fine.   but i got an error "The underlying connection was closed: An unexpected error occurred on a receive." when the return object is getting complex.   i analysis the issue with different level of object complexity and i found it get failed for following structure.   eg:   ObjectA - outer object that has some primitive data types and the list of ObjectB ObjectB - this also contain some primitive data and list of ObjectC.   Hope you can understand the hierarchy (complexity) of the return object. This works up to 2nd level of object hierarchy.   Does anyone have idea about the solution for this exception?   Thanks in Advance Shazvi
