Error While Connecting SQL Server From VB.NET/ASP.NET
May 16, 2007
I installed SQL Server 2005 with Windows Authentication. While attempting to connect via Visual Basic.NET or ASP.NET using connection string (given below), it displays following error:
Connection String:
Data Source=MYLAPTOPRPK;Initial Catalog=testdb;Integrated Security=True
Error:

Hi,I need some help. I am getting this error after I complete the asp.net register control and click on the continue button. It crashed when it tries to get it calls this Profile property((string)(this.GetPropertyValue("Address1")));When I look at the stack, it is coming from my ProfileWrapper class which adds user address, city, etc.. from a class which inherits fromSystem.Web.Profile.ProfileBase. From the stack, it is calling the System.Web.Profile and crashed when it tries to open a connection atSystem.Data.ProviderBase.DbConnectionPool.GetConnection(DbConnection owningObject). I already migrated all aspnet_user, aspnet_roles, etc.. and don't get any connection errors. It is only when I try to get the profile data. This works on my pc, but throws an error on my lunarpage website.Any help is greatly appreciated.Thanks,AJAn error has occurred while establishing a connection to the server.

I am having a problem adding a new server or going into my previously registered servers. I was using Sql express and now using the full version of SQL 2005. When I try to coonect to a server, In the server type I choose Database EngineServer name I typed in LOCALHOSTSQLEXPRESS, no names show in the dropdown for server, leave use windows authentication selected. then hit the advanced button and change the network library to shared memory, hit test button and get this error: "An error has occurred while establishing a connection to the server. when connecting to sql server 2005, this failure may be caused by the fact that under the default settings sql server does not allow remote connections. (provider: shared memory provider, error: 36 - the shared memory dll used to to connect to 2000 was not found)" any input would be appreciated. thanks.
I have a perplexing problem. I've developed an ASP application for our internal business use. I'm getting ready to launch, but every once in a while the application can't connect to the database. The error I get is: An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) We (IT and I) turned off the remote connections and it still happens. I'm afraid of launching without understanding what causes this and gettign a fix. To get it working again, we restart IIS and it works fine. I used VWD 2005 Express and it's running on SQL Server 2005 Express. Thanks for any help you may have.Scott J.
Ok, I'm new to all this, so please keep that in mind. I've built my first asp.net site and it works fine locally, but isn't working after I upload it. The site was setup to utilize asp.net 3.5 framework automatically, but since the host uses 2.0.50727.42, I adjusted the site to utilize 2.0 framework (hopefully that worked ok). The host is running an SQL 2000 server, so maybe my problem has to do with that, since the error is saying SQL Server 2005 (which is what I have installed locally). If this is the problem, can I adjust the files in Visual Studio somehow to work with a SQL 2000 Server? Here's the error: An error has occurred while establishing a connection to the server.

Hi All,I've written an ASP.NET 2.0 app that is working perfectly on my local machine when using SQL Server Express 2005 as a data source. To connect to Express I'm adding a connectionString in my Web.config file:<add name="libInstruct" connectionString="Server=localhostSqlExpress;Database=theDatabase;Integrated Security=True;"providerName="System.Data.SqlClient"/> I'm trying to migrate this app to our SQL Server box for live production use. I have detached the database from SQL Server Express 2005 and attached it in the production SQL Server box. Our SQL admin has created a SQL server username and password (not Integrated Security). All I have done is change the connectionString in my Web.config file to: <add name="libInstruct" connectionString="Data Source=the server IP address;Initial Catalog=theDatabase;User Id=theUserID;Password=thePassword;"/> Are there steps in the process that I am missing? I'm getting an exception when I try to connect to the db - System.Data.SqlClient.SqlException: Login failed for user 'libInstructWriter'. Reason: The password of the account must be changed.Thanks for any help you can offer! Thom CoxMedford, MA
I`m new to posting to this group so please keep that in mind while I fumble through my explanation of my problem.
I am building an operational data store and have a staging server where I encountered the following sequence of events. I need help in getting back to square one.
- This server has Win NT 4.0, SQL Server 6.5 with service pack 4, and Informatica PowerMart 4.04 on it.
- While using PowerMart to transform some data either SQL Server or Informatica locked up and Informatica gave message it could not communicate with the server.
- I could not connect to server using SQL Enterprise Manager. Thinking that I might have run out of user connections I stopped the Informatica and SQL Server services and then restarted SQL Server in a minimal configuration mode. I used sp_configure/RECONFIGURE to increase the number of user connections and was then able to connect to the server but couldn`t do anything because I got a `not enough memory` error. Again, I used sp_configure/RECONFIGURE to increase memory.
- At this point, trying to connect to SQL Server with Enterprise Manager gave me a `cursor is not open` error. I couldn`t find anything about this error in Books On Line.
- Knowing that I had to re-install SQL Server eventually (wrong sort order) I attempted to remove SQL Server before re-installing. The removal process was interrupted and did not complete normally.
- I deleted the C:Mssql.. directory and then attempted to re-install SQL Server using the BackOffice installer. Installation seems to be fine until the very end where I get an error that it can not connect to SQL Server and it fails.
- I have no option to remove SQL Server and can not get past the failure to connect to server error at the end of the installation process so what options do I have to get SQL Server back?
when i tried connecting to SQL Server Express I got this error, be it connecting via Windows Authentication or SQL Authentication. Pls see below for the error message:

According to this article: http://support.microsoft.com/kb/914277 I am supposed to:
1. Click Start, point to Programs, point to Microsoft SQL Server 2005, point to Configuration Tools, and then click SQL Server Surface Area Configuration. Ok, there is no such program in this folder. The only thing in there is "SQL Server Error and Usage Reporting"... The other thing I am greatly concerned with is this: All is want is for my webpages to be able to access my database for user authentication. I DO NOT want to grant the internet rights to remote connect to my database.

My application is working fine when i use broadband. but when i change my settings to dialup the application won't connect to sql server.
Details about project:
Connection string is IP based. Sql Server 2000. Framework 2.0 Sql Server is on hosting Servers. Application will be running on any system that has internet connection. The records that the application will fetch are not much, max 6 records in every 15 Secs.
Application is working fine on cable internet but when i switch to dialup it won't connect not even once.
dialup speed is good enough.
If you need any other detail please tell me...
Thanks in Advance. Erphan Rajput.

I can remote desktop and connect through SQL Management Express, but when I try this on my local machine I get the error 26
My knowledge is very limited and could do with some expert help
PS EDIT I read somewhere that in TCP/IP properties all IP's should be set to 1433, is this correct at the moment, apart from ALL IP which is set to 1433, IP1-9 are set to Dynamic Port =0, should I be setting all these to 1433
i downloaded and installed SQL SERVER 2005 EXPRESS. i tried to convert an "ACCESS" database to sql and got the next error:

I am trying to connect to a remote sql server 2005. So I have install the Microsoft SQL Server Management Studio Express. When I try to connect I get the error below.
An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) (Microsoft SQL Server, Error: 53). Can some one please help. I have even port no 1533 on my pc. Thanks.
An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this I use Microsoft Windows Vista Home Professional I have already installed to my computer Microsoft SQL Server 2005 and SQL Serves Express. I used to be successful to connect to the SQL Server but now I CAN NOT.
Not: I try to run SQL Server 2005 but I can not, even I logged on to my computer with an administrator rights. On the other hand I can start and stop the SQL Server Express easily.
As a result, how can I solve this problem. Thanks in advance. Bilgin Kılıç Additional Details

I'm new to using VS2005 and this is my first project connecting to our MS SQL 2000. App worked fine on my dev PC, connection to the same MS SQL Server. Published the web site to the web server (same server running MS SQL Server) and getting the below error. Is this a permission setup problem on SQL Server or does it really think it's connecting with a MS SQL 2005 database? An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections.

My environment is Windows Server2003, ASP.NET 2.0, SQL Server 2000 using SQL authentication (names of DB's, sql id's, passwords are identical on both servers) My web application successfully connects to my database the web app and the DB are both on the same server (10.144.25.9).This connection string works: <add name="DefaultDataTierConnectionA" connectionString="Data Source=10.144.25.9,1433; Network Library=DBMSSOCN; Initial Catalog=9D_SQL; User ID=******; Password=******" providerName="System.Data.SqlClient"/> PROBLEM: The problem occurs when the DB is mpved to the remote SQL Server (10.144.25.10). I use almost the identical connection string except for the IP address which is changed to the remote machine. The db name, user, password is same on remote machine as on the local, so everything should work but does'nt. This connection string fails: <add name="DefaultDataTierConnectionA" connectionString="Data Source=10.144.25.10,1433; Network Library=DBMSSOCN; Initial Catalog=9D_SQL; User ID=******; Password=******" providerName="System.Data.SqlClient"/> error (odd error in that I'm connecting to SQL 2000?) - An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: TCP Provider, error: 0 - A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.) 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.

(provider: TCP Provider, error: 0 - A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.) There is no DBA on this project, I'm not sure this is a SQL Server set up problem?
I'm experiencing a problem connecting to a SQL 2000 server through my ASP code. My connection string is as follows: <add name="TheConnectionString" connectionString="driver={Sql Server};provider=MSDASQL;server=10.0.1.42;database=dbname;uid=*********;pwd=*********" providerName="System.Data.Odbc" /> The problem doesn't occur when I run my ASP code from my workstation using VS.NET's builtin webserver. It makes the connections and executes the CRUD commands successfully. However, when I publish my site to the webserver (which resides on 10.0.1.16) it fails out with the following error: System.Data.Odbc.OdbcException: ERROR [08001] [Microsoft][ODBC SQL Server Driver][DBNETLIB]SQL Server does not exist or access denied.ERROR [01000] [Microsoft][ODBC SQL Server Driver][DBNETLIB]ConnectionOpen (Connect()). I've verified that the webserver can talk to the DB server by connecting to the remote DB server through SQL Enterprise Manager running locally on the webserver. If I try to do this with a DSN I get the same results. I get the same error from any other webserver on the internal network. The difference between my workstation and the internal network is that I'm using a VPN to connect to our internal network while the webservers are physically connected to it. Firewalling isn't the issue in this case because the webservers and DB server are on a trusted network. I've seen other ways of connecting to the DB server including using Named Pipes (which I would rather not do because I don't want to setup a named pipe on the production db server). I'm relatively new to ASP.NET 2.0, so the above connection string is an adaptation of some old ASP code. If anybody has any suggestions on a better way to construct this connection string, please let me know. I've been racking my brains trying to get this to work outside of the devel env.
Just manged to install sql server 2005 express after two days. I have a problem now! When i try to connect to it via my browser (local database), i get the following error: An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) I have opened the surface area configuration manager and set the connections to remote and local but it still doesnt work
Newbie strikes again.. I'm attempting to connect to a SQL Server database (using VS 2005). My code generated no errors in the build but when I tried to access the database, I got the following message:"The ConnectionString property has not been initialized."My connection string is stored in my web.config file. My code goes as follows:Dim strSQL As String = "SQL string stored here"Dim objConnection as SqlConnection = New SQLConnection(ConfigurationManager.AppSettings("name of connection string is here"))Dim objCommand as SQLCommand = New SqlCommand(strSQL, objConnection)objConnection.Open()Then I go on to open my reader and such. Where should I be initializing the ConnectionString property?TIA,Lesley
I've been trying to configure remote connections to my sql server express to no avail.
First here are some constants to clear some things up: - OS: Windows XP Pro - SQL Express version: April CTP release - Windows Firewall: disabled (to avoid any problems there) - Network type: two computers connected a router. - Router firewall: Enabled (I may be wrong but the router firewall only blocks external traffic, so I left it on.)
First, I configured my SQL server to allow remote connections in the SQL Surface Area Configuration. (Set it to both TCP/IP and named pipes)
Second, I enabled and configured sql server browser.
Third, I enabled TCP/IP and named pipes in the 'Protocols for SQL Express' option of the SQL Server Configuration Manager.
According to http://blogs.msdn.com/sqlexpress/archive/2005/05/05/415084.aspx I have done everything I need to (including edit the registry to enable the SQL Server Browser service) and the error I continue to get is:
"An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified) (Microsoft SQL Server, Error: -1)"
So I tinkered and had no success in messing with anything that would fix it. Although, ***when I browsed for network servers on different machine, the server instance DID show up in the list***. So I find it odd that it can find the instance when browsing, but fails to 'find' it when making a connection.
So I didn't stop there, I decided to try the non-sql server browser method of remotely connecting: specifying the IP.
I went back to the blog of instructions referenced above and re-did the steps, this time specifying a TCP Port for the server instance and then after specifying the port on the remote computer connection string, and attempting to connect, I get this error:
"An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: TCP Provider, error: 0 - A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.) (Microsoft SQL Server, Error: 10060)"
I've done all I know how, read all the possible blogs I can, and nothing's come up. If anyone can shed some light on me, I'd pay you 1 billion pretend dollars. Any help would be appreciated. Thank you!
