SQL Server Connection Client Tried To Connect To An Unsupported Version?
Jul 21, 2010
We recently launched a new web site.there are roughly ~150 users active during peak hours.During peak hours,we are experiencing an issue every few minutes,the exception text is listed below.
System.Web.HttpUnhandledException:
Exception of type 'System.Web.HttpUnhandledException' was thrown.
---> System.Data.SqlClient.SqlException: The client was unable to establish a connection because of an error during connection initialization process before login.
Possible causes include the following:
the client tried to connect to an unsupported version of SQL Server;
the server was too busy to accept new connections;
or there was a resource limitation (insufficient memory or maximum allowed connections) on the server.(provider: Named Pipes Provider, error: 0 - No process is on the other end of the pipe.)
Our data access layer calls various DataTableAdapters using the following syntax.
EDIT
Yes, da is the name assigned to the DataTableAdapter. There is no connection.Open() because the DataTableAdapter takes care of all that, right?

I have installed Visual Studio 2010 ultimate (trial version) on my PC,it's working fine but i am getting issue with sql server 2005,it's not working now.
I m using SQL Server 2005 Express edition.The error when i am trying to connect sql server with windows authentication is
"This version of Microsoft SQL Server Management Studio Express can only be used to connect to SQL Server 2000 and SQL Server 2005 servers. (Microsoft.SqlServer.Express.ConnectionDlg)".
I am having trouble installing SQL Server on my system ... it appears to install ok but when I try to connect it using Visual Web Developer Express 2008 it will not connect and mentions something about versions. I downloaded the Northwind database to carry on with the tutorials .. this also asked me to download the MS SQL 2000 version which I tried and this also did not work, other versions include 2005 and 2008. When I tried to open the program through the programs file from "Start Menu" only the configuration manager folder is there.
I have also tried to install the trial version from the website but to no avail. Each time I have restored to factory settings on my laptop and it still fails to connect. I notice that when I restore to factory settings there are loads of icons where the uninstall window lists all of the programs and there is still SQL Server 2008, lots of Icons. I think that version 2008 came with the laptop as it is a business sony vaio sr vgn-sr46gd model with vista business.
be it's a wrong place to ask the following question. Sorry for that. Our hosting provider has recently upgraded their database server from Sql Server 2005 to 2008 and I'm getting errors to connect with remote server from my development machine. Error Message "Invalid connection". Tried to find solution on net but couldn't find it.I'm using .Net 1.1. Though we've updated versions 2.0,3.5 & 4.0 but due to some certain circumstances I've no way to update it. It's a web based project. The following connection string works fine for Sql Server 2000 & 2005 but not for 2008.<add key="ConnectionString" value="Data Source=Remote Server's domain name;Initial Catalog=database name;User ID=user name;Password=surround;Persist Security Info=True;Pooling=false;Connect Timeout=45;" />Here Remote Server's domain name indicates to remote db server like: test.mysite4now.comdatabase name for example: test_surrounduser name like test_surroundpassword: surround.Can anyone inform me what's wrong with the above connection string to connect to Sql Server 2008.

I have an ASP.Net website running on IIS7. The Application Pool is set to ASPv4 Classic.
Authentication Mode is set to ASP.Net Authentication & Windows Authentication
My question is, when I want to connect to SQL using a "trusted connection" in the Connection String, what user will actually be passed into SQL?
I thought it would pass my logon details, but it is coming back with an NT AUTHORITYANONYMOUS LOGON error, which seems to point towards it not passing in my logon.

I have Visual Studio 2008 installed on this workstation with SQL 2000, 2005 Express, 2008 Express and I think 2008 R2 (not sure if that is a version itselve or not)
I will call that workstation HOME
I created some tables in SQLEXPRESS through VS2008.
I worked on this project on another workstation that I just installed VS2008 annd SQLEXPRESS 2008 and I know that was R2
Installed Visual Studio 2010 trial edition between the thiem I made the tables on HOME and tonight for the first time since that install
I am now getting the "cannot be opened becuase it is version Version 661. This Server supports version 655..."
What to do now?
I can opened SQLExpress 2008 management studio and it is running.
So is my SQL 2000. The problem seems to be that after the VS2010 install neither VS2008 or VS2010 can connect to the SQLExpress 2008
What do I do now?
I can't remove sql 2000 because it is tied to several 3+ gig databases that will not work in Express.
I just installed sql server 2008 R2 on my computer. I am trying to connect to sql server throught my C# code and everytime I run the C# program,
I get this 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: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) "
The connection string that I used in my web.config file is

I am not sure what am I doing wrong, but I followed this article below step by step and still I am getting the same error
I need to get the latest version of DotNet installed on the machine in which my App is running. How do I get that?
I have an app which I distribute to several people. Now, If one person who runs the app has .NET version 2.0 installed, I must get that info...and if another guy has 3.5 installed, I need that info .I tried with the Environment.version, but that gives the version of the application .
I am having the error stated above. The stack trace is as follows:
[Code]....
Some info's:Server: Windows Server 2008 R2
.NET Framework Version:4.0.30319; ASP.NET Version:4.0.30319.1
Oracle.DataAccess, Version=1.102.3.0bit
.NET Framework Version:4.0.30319; ASP.NET Version:4.0.30319.1
Oracle.DataAccess, Version=1.102.3.0
My Code: OracleConnection cn; String con1 = ConfigurationManager.ConnectionStrings["myConnectionString"].ToString(); cn = new OracleConnection(); [code]....
I have checked all forums and posts regarding this error. They mention that there are 2 versions of Oracle.DataAccess.Client on the server, I only have 1 version. This runs on VS2010, but when I publish the website the error above shows up. I checked my Oracle connection from the installer and connection test passed. I tried uninstalling Oracle and reinstall, but still the same. The query above I tried changing to 'select region_code, reg_rom, ...', still the same error..
I have a website in which code on the production server runs no problem. The same code on my local machine or test server produces the mess seen at the end. The exact same code. Additionally, upon trying to preview any of the table adapters in the dataset I get "DataSet1.thename could not be previewed. The provider is not compatible with the version of Oracle client"
The app is SQL Server. It always has been. It has never used Oracle. Does anyone have any insight on how to fix this? As it is now I can't do anything with my dataset. I can't edit anything in there because of this complaint about Oracle.
We have an ASP.NET web application and it's hosted using IIS 6.0, in the app we have these several javascript and css files located in a folder, and for performance sake (according to YSlow) we set the folder content expiration header to 1 year. Everything worked just fine until recently when we deployed the latest build to the server, in which we had made some changes to those javascript and css files. For some reason after the deployment some of our end users don't see the latest changes when they connected to the app, even after they cleared the cache in IE. We have also restarted the IIS on the server and the problem still remained. When I went into the IE Temporary Internet Files folder on one of these machines I saw the files were still the older version and not the latest one, I had to manually delete the files from the Temporary Internet Files folder then they were able to see the latest changes. I'm baffled by this, how come only some users who couldn't see the changes but some others do (without having to do anything by the way), and how do I make sure that for future releases we won't have to do anything like what did (manually deleting the cached files)? For now I disabled the Content Expiration option in IIS for these files but I would like to know if there is a way that I can enable the content expiration (to help performance) but at the same time making sure when the files are updated, the latest version will be used for the end user (instead of the cached version)?
