Can No Longer Connect To SQL Server Express Error:40
Jan 14, 2007
Hi,
I have been working for a few weeks on a local SQL server (express) on my computer all worked ok, until 2 days ago I got the following error message:
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: 40 - Could not open a connection to SQL Server) (.Net SqlClient Data Provider)
Where can I find the setting for remote connections? Also any idea why this happened?
Everything was working fine. I have been able to connect using windows authentication. Then, I went into the ODBC manager to add a data source and it failed to connect so I went back into the Server management studio to modify users. After doing this I now get an error when I try to conenct the management studio to the SQL server.
I wasn't modifying the login for my windows account that I normally use, I was modifying a different one, however I now get the message "An error has occured while establishing a connection to the SQL server. This kind of problem can ocure because the default behavior of the server does not support all connection methods" blah blah.
Does anyone know how I can attach to the server? Or, do I need to somehow remove the server and create a new one? How would I do that?
Additional Information: An error has occured while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that unthe default settings SQL Server does not allow remote connections.
I used to have both SQL Server 2005 Express and SQL Server Management Studio Express up running just fine until I installed (removed SQL 2005 Express) SQL Server 2005 for Developers and re-installed SQL Server Management Studio Express - now, SQL Server 2005 for Developers works, but I can not start SQL Server Management Studio Express? No error messages, simply nothing happens when I execute ssmsee.exe. Should I be using a different version of Studio?
I have been for years using the following code locally in native ASP (except different UID and PWD and file path for the msado15.dll) with SQL Server 2000 on XP to do my development and then I upload to the web site later (uses different objConn etc when live). I've now tried to use the same for SQL Server Express and Vista and always get the "does not exist or access denied" error ( 2147467259).
I only want to use SQL Server locally from the machine I'm developing on as I upload the tested "ASP" code to the server which runs it. The SQL Server Browser is running and I have checked the Firewall exclusions for sqlservr.exe. Also I installed it with out Windows Logon (same as I had for SQL Server 2000).
Any ideas, I tried using the Data Source=localhost instead of explicitly defing the path except that had no affect either, I also changed the rshstest_data.mbf to rshstest.mbf as well also to no affect as there appears a difference with this in 2000 and Express?
Any suggestions would be appreciated, thanks..

I have installed sql server 2005 Express with SQLADV.exe. But when I open Management Studio Express it has error:
Can not connect to 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.

Hi. i got an error when i connect to sqlserver 2005 db with use of Sqlserver ManagementStudio.
A connection was successfully established with the server, but then an error occurred during the login process. (provider: TCP Provider, error: 0 - The specified network name is no longer available.) (.Net SqlClient Data Provider)(Microsoft Sql Error - 64)...
We just upgraded to SQL Server 2005 from SQL Server 2000. The DB was backed up using Enterprise Manager and restored with SQL Server Management Studio Express CTP. Everything went as expected (no errors, warnings, or any other indicator of problems).
The DB resides in a DB Server (Server1) and the application we are running is a Client/Server system where the AppServer resides on Server2.
During the application's operation all read, create, and delete transactions work fine but no update works. When viewing details in Trace Log I see this message after attempting any update:
Could not find server 'Server1' in sysservers. Execute sp_addlinkedserver to add the server to sysservers. (7202)
I'm having a problem connecting with a Java application but I CAN connect using my .Net application - the user name and password are the same for both (using the same database on SQL Server Express 2005).
The error I get is: "com.microsoft.sqlserver.jdbc.SQLServerException: Cannot open database "CORNERS" requested by the login. The login failed." An interesing note - I get the same message if the database is not running.
SQL Server Express 2005 is installed in mixed mode.
Here is my connection string in the .Net appplication: <add key="connectString" value="Server=(local);UID=sa;PWD=myPasswd;Database=CORNERS" />.
I've seen the following error posted when people try to connect to their server via their applications but didn't see anyone having problems when trying to connect with SQL Server Management Studio Express. Am I missing something here? This is the 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)(Microsoft SQL Server, Error: 2)>>The server is not remote so I don't see why I need to enable remote connection. I am also using the default connection settings.
On my home machine without permanent network connections enabled, I cannot get the Management Studio connect to the database server. Always get this error:
Cannot connect ot MPLIAMSQLEXPRESS
Additional Information:

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.

I have used the SQL Surface Area Configuration Tool to reset the defaults to allow remote connections, stopped and restarted the server, but still get the same message.
Hi we have a table with about 400000 records in it. It starting to take longer and longer to add a new record. I was thinking of creating another identical table and archiving off most of the records every month (we are now adding about about 4000 records a day) . Is this the best thing to do? I don't know a lot about sql server so any help or suggestions would be great
Hey all! I am new in this form and also new with the SQL serve. I have installed that free express edition of SQL server 2005 and when i am trying to connect to server from my C#.net application i am not able to do it and when i am trying to degug it gives me the error that is the user is not SQL thrusted user. I am able to connect directly thru SQL server using this userid and password but not thru VWD 2005 Express application.
I have read online that so many people are having that problem. so is it the problem of swl server Express edition or do i have to make some setting to connect to the application.
Please please please please someone guide me . I am stuck here in the beginning only. I would really appreciate it.

I have Remote Connections enabled (I think). Any advise is greatly appreciated.
I'm trying to connect a DB in SQL express with a program in VB.NET Express. I'm using the Data Source Configuration Wizzard. When I select the file (.mdf), the following message appears:
Unable to open the physical file "path to my file". Operating system error 5: "5(error not found)".
An attempt to attach an auto-named database for file 'myFile' failed. A database with the same name exists, or secified file cannot be opened, or it is located in UNC share.
I'm using the Windows authentication for this, but if I try with the sa user, I get the following message:
Failed to generate a user instance of SQL Server. Only an integrated connection can generate a user instance. The connection will be closed.

I am receiving errors from a job that no longer exists. The databases created for this no longer exist also.
DATE/TIME: 4/6/2007 3:32:00 PM
DESCRIPTION: The log shipping secondary database LOG1.log_ship_test has restore threshold of 45 minutes and is out of sync. No restore was performed for 6004 minutes. Restored latency is 0 minutes. Check agent log and logshipping monitor information.
COMMENT: (None)

I have gone into agent jobs and deleted those associated with it. I have also gone into the msdb database and deleted any lines associated with it in the log_shipping tables. But the errors keep coming. What do I need to do to clean this up?
I'm running Vista Ultimate. SQL 2005 is set as my Default instance, and SQL2000 is set as (local)SQL2000.
Today, actually half way through today, I restarted my computer after installing Photoshop Updates.
Upon getting my computer back up and running, I cannot access SQL2000 from any website on my computer, nor can I access it from SQL2005 Management Stdio. I CAN access it from Enterprise Manager (SQL2000 tool).
Whenever I run an web app that connects to it 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: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)
Now I usually get these when ASP.NET can't point to the right spot, but in this case I'm pointing exactly where I need to go. Any thoughts?
--Edit
I should also add my password got changed a few days ago on our Domain. This was the first time restarting after the PW change.

Hi everyone I have some problems with SQL server. I just installed the SQL Server 2005 express edition on my computer. And after installation, i cannot connect to it.

Both authentifications doesn't work when I tried to log in The following is the error I get :"Cannot connect to localhost. An error has occurred while establishing a connection to the server. When connecting to SQL server 2005, this failure may be caused byt he fact that under the default settings SQL server does not allow remote connections."Can somebody please help me ?

I ran the upsize wizard on one of my databases to SQL Server 2005 Express. I can connect to it just fine. I have 3 test users and they cannot. They get the following:

just installed a new machine with windows 2003 server and SQL SERVER EXPRESS; I am able to connect to the SQL Server using my windows credentials however I am unable to log on to it using 'sa' (and no password) user; i get the following error message.

I'm trying to connect to a SQL Server 2005 express on my local Windows XP Professional machine. I've searched the the MS fora and Google but all the answers I find relate to trying to connect to a remote DB, not local.
I run the aspnet_regsql.exe program in the interactive wizard mode, and in the Select the Server and Database step when I click on the Database drop-down list an error box pops up:
Connection failed
Failed to query a list of database names from the SQL server.
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)
Exactly the same error message appears when I:
* Change the 'Server' name from my computer's name to localhost, 127.0.0.1, or SQLEXPRESS. in the aspnet_regsql wizard.
* Stop my firewall (ZoneAlarm, native Windows firewall is disabled, and I switched off my cable modem at the time).
* Use the SQL Server surface area utility to enable remote connections with both named pipes and TCP/IP), and also to enable CLR integration in the Features section.
* Stop the SQL Server service. I did this to see if a different error occurred, but it's as if aspnet_regsql.exe can't even see the SQL Server.
* Have an additional instance of SQL Server running under my own username (see below).
I have an ASP.NET project (created by someone else on another computer) which attempts to open a SQL Server database. It runs fine until the call to System.Data.SqlClient.SqlConnection::Open() which raises an exception with exactly the same error string as above (including what's in parentheses). The connection string is "Data Source=localhost;Initial Catalog=blah;Integrated Security=SSPI;" where blah is specific to the company I'm doing this for.
I've created a test ASP.NET project to which I added a SQL Database. My only option was to create a .mdf file in the APP_DATA folder. The connection string is "Data Source=.SQLEXPRESS;AttachDbFilename=|DataDirectory|Database.mdf;Integrated Security=True;User Instance=True" and it works fine and displays the data I've put into the database, but in the Task Manager another instance of sqlservr.exe appears (running under my username; the existing sqlservr.exe runs under the NETWORK SERVICE username). Should this happen??
If I stop the SQL Server service (or both of them), an error message in my web browser appears (no exception is raised because there's no code in the project, just a data-bound control). The error is the same as above, except the parenthetical part is "(provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)".
Edit: oh yeah, I've also tried to set up an ODBC data source connected to SQL Server throught the Control Panel/Admin, but the ODBC applet can't seem to see SQL Server either. I only get three options for data sources: dBASE files (.dbf), Excel files (.xls), and MS Access Database (.mdb). If I click on 'Add' and select "SQL Server" and go on from there, it comes back and says the server doesn't exist or refuses access. If I stop the service, the ODBC applet says the sql server wasn't found.
I'm using a Windows XP Home laptop to connect to a network of one of my customers. The administrator of the customer has given me a username and password for a VPN connection. I've got the VPN connection working and I can ping the SQL Express server.
This server is using Windows Authentication. For the users of my VB application we have added a group to the Active Directory and added this group as a user to the SQL Express Server. This works and the users can access the database from within the application. The SQL Express Server allows remote connections and the browser service is also running.
I would like to use the SQL management Studio Express on my laptop to access the remote SQL Express server and manage the database files. To do this I first connect to the remote LAN using VPN and add the address of the SQL EXpress server in the field 'Server name' of the 'Connect to server' screen. The authentication field is set to Windows Authentication. However the username is greyed out and states the login for the SQL Express server on my laptop: laptopusername. How can I correct this?
I don't know whether the username of the VPN connection is in the Active Directory. Should this be the case and should this user also be added to the login/user of the SQL Express server? And how do I get the Management Studio to connect to the remote server? Could XP Home be the bottleneck as it cannot logon to a domain?
Is there a limitation in sql server 2005 express that it does not accept connections via the network? I am trying to develop a web application running the web server as a VM but I can't connect to the sql server on the host machine. Similarly, I can't create an ODBC connection on the VM, but I can on the host. I could install sql express on the VM, that is probably the next thing I'll try.
I can't connect to the local sql express server. I see in microsoft sql server management studio express that the server is running but I don't fint the server in access 2003. I work with vista. what can be the reason?
