System.Data.SqlClient.SqlException: 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)
I have enabled the remote connection in the surface area configuration, and i've also enabled my sql browser.
This error raised when i'm testing my just installed WSRFdotnet using
NUnit testing, however, when I tested my remote connection using SQL
Server Management Studio Express CTP, it worked. btw, I'm using SQL
Express
any solutions?
thx

Hi.Its really become a nightmare solving remote SQL Server connection. I thought it was going to be easy. Anyway im using win xp sp2 and sql 2k5 express as testing environment. I followed trouble shooting
tips:
http://blogs.msdn.com/sql_protocols/archive/2006/09/30/SQL-Server-2005-Remote-Connectivity-Issue-TroubleShooting.aspx
and secured all requirements to met one by one.
I created a test script (ASP) running on the same box where the SQL Server was installed and its running perfectly (eg http://127.0.0.1/sql.asp OR http://localip/sql.asp) either using one of the following connection string
cn.Open "Driver={SQL Server};" & _
"Server=live-static -ip;" & _
"Address=local-ip,1433;" & _
"Network=DBMSSOCN;" & _
"Database=xxx;" & _
"Uid=xx;" & _
"Pwd=xxx;"
OR
cn.Open "Provider=sqloledb;Network Library=DBMSSOCN;" & _
"Data Source=local-ip,1433;" & _
"Initial Catalog=testdb;" & _
"User ID=xx;Password=xx;"
now i upload the page to our domain host and try to access but its sending an error:
################ ERROR MESSAGE
Microsoft OLE DB Provider for ODBC Drivers error '80004005'
[Microsoft][ODBC SQL Server Driver][TCP/IP Sockets]SQL Server does not exist or access denied.
/sql.asp, line 6
########################################
sql browser is also running, and remote connections allowed, port exemption and firewall is turn off but im receiving the same error.
where im getting wrong.

Through the SMS tool, the following error is being received:
===================================
Cannot connect to MyServerMyInstance.
===================================
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) (.Net SqlClient Data Provider)
Note: obviously the server/instance of MyServerMyInstance is fake :).
The setup is the developers receiving this error are connecting to the domain remotely through a VPN connection (so they are on a different, non trusted domain). Also, the IP address our server is on uses an internal range that the remote developers already have in use for something else on their network. So we gave them a bogus IP to use where we then perform a 1-to-1 NAT translation on our end to the correct IP. This all appears to work but the developers still receive this error.
We do have remote connections enabled for both TCP/IP and NetBIOS and everyone at our office can connect just fine. With this in mind, what could be some other issues that can cause this? The only other thing I can think of is somewhere (there are 2 firewalls involved - ours and theirs) is that the UDP packets are not being received by the client.

I am converting over from MSDE to SQL Express. My front end program is unable to connect to the database. To troubleshoot, from the remote computer I tried connecting with the management program and I get the Error 26 unable to connect.
Here is what I have done: I made sure that the SQL Server configuration has been changed to allow network connections (both TCP and named pipes). I have disable windows firewall on both machines. I confirmed that I can connect from the remote machined to the server by network browsing. Both machines are running XP Proff. There is no other security software running on either machine.
More Info. when attempting to log on I am using the server authntication, I use "sa" as the user id plus my password.
Goal. The front end of database program connects to the server remotely using a program called Hamachi over the internet. This works without a problem on MSDE. But for now I am simply try to connect using the managment program which lets you browse for other serves. When I do this it shows the remote computer, but not the name of the computer but not the SQL server which I type in like the following: "INTELsql1"
What I have not Done: I have not changed any permissions or added any users to the server, since this does not seem necessary. As stated the user of remote machine can connect to the server and change files.
Would appreciate any suggestions or tips. Thanks.

Its been almost 2 months i start running a test script page to check if i made the remote connection until now its getting worst.
I did follow every bit of the instruction and pre-evaluation in fact the script is working locally with this string:
cn.Open "Driver={SQL Server};" & _
"Server=global-static-ip;" & _
"Address=local ip,1433;" & _
"Network=DBMSSOCN;" & _
"Database=testdb;" & _
"Uid=xx;" & _
"Pwd=xx;"
i also review the ff post for client and server trouble shooting tips:
http://blogs.msdn.com/sql_protocols/archive/2006/09/30/SQL-Server-2005-Remote-Connectivity-Issue-TroubleShooting.aspx
surface configuration, sql browser, firewall exemption...
and nothing seems change when i access the uploaded script.
is there anything i am missing?
by the way the script is uploaded by company.

I am trying to connect to an instance of SQL Express through a vpn, simply using the SQL Management Studio, providing the server ip address x.x.x.xMSSQLSERVER, and using SQL authentication login. I receive the following message:
Cannot connect to <server>, etc., etc.
error 25: - Connection string is not valid
Does anyone understand this? I am trying to connect through the SQL Server Management interface, not with a client program that would utilize a connection string. Is there something which prevents Management Studio from working over a vpn?
To connect, I am using SQL authentication, and have verified the login and password locally on the target pc. The SQL browser service is running on the target pc, and I can telnet to the port which it is monitoring, through the same vpn connection. Remote connections are enabled for TCP/IP in the Surface Area configuration on the target pc.
Any help appreciated.

Overview. I am converting over from MSDE to SQL Express. My front end program is unable to connect to the database. To troubleshoot, from the remote computer I tried connecting with the management program and I get the Error 26 unable to connect.
(The connection string worked previously (yesterday) when using MSDE as the server. When I installed SQL Express I named it the same instance as the server name under MSDE. I also use server authtication on both with same user name and password. As stated below I cannot connect using the managment console.)
Here is what I have done: I made sure that the SQL Server configuration has been changed to allow network connections (both TCP and named pipes). I have disable windows firewall on both machines. I confirmed that I can connect from the remote machined to the server by network browsing. Both machines are running XP Proff. There is no other security software running on either machine.

I have a visual basic 2005 application where I am storing some data in a Sequel Server Database. It's my first attempt using SQL Server. It was developed on my machine and the database is on my local hard drive.
It was put onto an industrial PC and shipped last December (the vb app is an HMI).
Our service guy is installing the machine and asked for some changes to the VB screens. I ran my app (on my computer) and it crashed when I selected the screen where I use the db.
So I decided to look at the database using Visual Basic and I get the following error:
Microsoft Visual Basic 2005 Express Edition
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)
I then tried to create a new database via Visual Basic and get the same error. My boss has it installed on his machine. Same error there. These are both machines that had no problem back in December!
I also have a industrial PC on my desk to test my app and it STILL WORKS there. That one though is not connected to the internet and hasn't gotten any updates or changes or whatever since I last had it on in December. I don't know if it was a windows update or a network change? But as I said, I'm not connecting remotely - SQL Server and the db are on our local machines.
Interesting enough, if I go to the control panel | Administrative Tools | Services, SQL Server (SQLEXPRESS) is set to automatic and is NOT started. I attempt to start it and get an error
Services
Windows could not start the SQL Server (SQLEXPRESS) on Local Computer. For more information, review the System Event Log. If this is a non-Microsoft service, contact the service vendor, and refer to service-specific error code 3417.
I am lost.
Thanks in advance for any help!

On my computer (WinXP En Prof SP2) I have installed SQL Express 2005 with instance name "SQL2005". Mixed Mode.
I allowed Remote connection to this DB server, enabling TCP/IP protocol on port 1433.
Also SQL Browser is set to autostart.
My firewall is off.
When I try to connect to this server through the CMDline, I use:
sqlcmd -S testpcsql2005 -U sa -P test
I only get: "Sqlcmd: Error: Microsoft SQL Native Client: Client unable to establish connection due to prelogin failure"
If I use:
sqlcmd -S testpcsql2005 -U sa -P asdfghjkl (or any password)
the result will be the same.
If I try to connect to the server through the Management Studio, I just get:
"A connection was succesfully established with the server, but then an error occurred during the login process. (provider: TCP Provider, error:0 - An existing connection was forcibly closed by the remote host.)(Microsoft SQL Server, Error: 10054)"
or
"A connection was succesfully established with the server, but then an error occurred during the login process. (provider: TCP Provider, error:0 - An established connection was aborted byt the software in your machine.)(Microsoft SQL Server, Error: 10053)"
Next I have installed the new DB on new computer (WinXP En Prof SP2) with the same options (using unattended installation in CMD line) and on this computer it works. It means, that I can establish remote connections to that server with any problems.
I have search on internet to solve this problem bud a I didn't find the solution. I found, that this error relates to winsock layer - WSAECONNABORTED(10053) and WSAECONNRESET(10054) error codes.
But I still don't know, how to solve this and remotely connect to my DB Server...
Thanks for your answers.
Edit 1:
I have tried to uninstall MS Net Framework 2.0, Microsoft SQL Native Client, Microsoft Support Files.
When I try localy connect - it doesn't work, of course.
When I try remotely connect:
"sqlcmd -L" shows, that exists "testpcsql2005"
"sqlcmd -S testpcsql2005 -U sa -P asdfghjkl" (or any password) generate the same Error as before - nothing changed
Is it problem of MS SQL Server or MS Windows? How to solve this?

Help! My web-application worked fine last week. I have made some enhancements and it still works fine when I test in locally in VS 2005 and from IIS when I allow unauthenticated users (by commenting out "<deny users="?"/>" in my web.config. However, with not allowing unauthenticated users, I get redirected to a login application (which also worked last week), where I supply one of several user names and passwords and it is supposed to redirect me back to my default.aspx page. Only, now it is taking the authentication parameters from the login screen but is not redirecting me back to my app's page and instead is putting up this Error 26 that states SQL Server 2005 does not allow remote connections.
The included stack trace has no information about what server it seems to be trying to connect with, but the strangest thing about it is I/we are not using SQL Server 2005 yet (still a future upgrade not too far off). The application database, the authentication aspnetdb database, and the Session aspstate database are all on the same SQL Server 2000 managed server. And, these were all working last week (and are all accessible). I have not changed any connection strings and as I said, it works fine without the loging in part both locally and from IIS. It is only when using the Login in application, which is working with other apps and the developer insists the problem has to in my application (after all the first line of the error message states: Server Error in '/deployment1' Application, which is my app!)
I am lost in finding the culprit, can someone please give me some ideas?

I am getting this error in Enterprise Manager:
TCP Provider: An existing connection was forcibly closed by the remote host.
But, my web app can still connect just fine to the db, so it's still in
the same place with the same login/password. And my registration
in EM was working just fine (for years) until yesterday I got this
error. I've tried deleting the registration and re-creating it
but the same thing. What could have gone wrong to cause this to
happen?
Thanks for any pointers, I have no idea where to start looking on this one, the host says they haven't changed anything...

OS: Win 2003 Service Pack I on 2 boxes
SQL: SQL Server 2005 Clustered System
Situation: I have created a maintenance plan to backup my transaction log every hour. This runs fine for some time and then later that day it stops working. This could happen at any anytime, and I end up having to manually kick it off again. I read the SQL error logs and this is what it points to:
[298] SQLServer Error: 2, Named Pipes Provider: Could not open a connection to SQL Server [2]. [SQLSTATE 08001]
[165] ODBC Error: 0, Login timeout expired [SQLSTATE HYT00]
[298] SQLServer Error: 2, 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. [SQLSTATE 08001]
[382] Logon to server 'JAXNVSQL1CLS' failed (ConnAttemptCachableOp)
[177] Job MaintenancePlan Insight Transaction Logs has been requested to run by Schedule 10 (Insight Transaction Log Backup)
[165] ODBC Error: 0, Login timeout expired [SQLSTATE HYT00]
I have already used SAC to confirm that remote connections is enabled using TCP/IP and Named Pipes. I have used the server configuration tool as well to check this. I have used the Studio Management and checked on the remote connections as well.
I know these protocols are enabled and working because I have used the Studio Management to check on the activity connections type and seen both are working. Plus the fact this maintenance plan does work, it just so happens something causes it later to fail. When this does fail, I log onto the server but can not login using the Studio Management , I get [298] errors. I can login using the Studio Management on my laptop remotely but can not manually kick off the maintenance plan. I end up having to log on to the server and restart the MSSQL Server service and manually kick off my plans. (By the way these services do not show shutting down in the Windows event viewer). After restarting the MSSQL Server service and manually executing the maintenance plan everything is fine until the next time it hits a glitch.
I do have SQL Browser up and running, all of the MSSQL services running, I need some help as to what may be causing this problem!!!!!!!!! HELP!!!!! I am losing my mind!!!!

If you connect to a server and open a query in SQL Managment studio (2005) and looses connection and then regain the connection, when you try to run the query it gives me a "TCP Provider, error: 0 - An existing connection was forcibly closed by the remote host." This happens against both 2005 and 2000 servers. If I re-run the query it works. However, this happens in our VB.NET app as well for clients with Wireless connections. So, something has changed in Framework 2.0 regarding this, does anyone know how to tell the client to not throw this error and just try connecting the server instead which will work?

What does this error mean? I get this in the transmission_status column of sys.transmission_queue
An error occurred while receiving data: '10053(An established connection was aborted by the software in your host machine.)'.
Also, does the number in this message correspond to error 10053 in sys.messages?
Thanks

I'm getting "Access denied" error when I try to connect to SSIS from my desktop (Database Engine is fine). I'm a member of sysadmin within SQL, as well as an administrator on the server. I don't have any problem when I log on to the server directly via Remote Desktop and open SSIS.
I went into the surface area config tool, and I see that Database Engine and Analysis Services both expand and have a sub tabs to enable Services and Remote Connections, but Integration Services does not expand to a Remote Connections option, just Services. We're running MSDN Enterprise edition.
Does it matter if all the SQL services are using "Local System" for the logon ? I use an administrative logon on my SQL2000 boxes, and was fiddling with them on the 2005 box yesterday, but it seemed to cause more problems, so they are all Local System for now.
Am I missing something obvious ?

Hi. I'm (very) new to SQL Server. I have run into what seems to be a very common problem, judging by the number of Google hits, but it's not actually in the FAQs here, as far as I can see.
Situation
I installed SQL Server Express with Advanced Services 2005 on my Windows XP Pro laptop, using (with one exception) the default install. The exception was to put the data files on a separate partition (D: ) where I have more free space.
SQL Server Management Studio Express connects happily, and I set up a single data import table.
Issue: bcp Fails to connect to default local instance
I initially tried bcp in output mode, prior to working in earnest on importing my data. However the command line-
bcp MyDatabaseName.dbo.UserProfile out UserProfile.txt -T -c
Fails with the error-
Error = [Microsoft][SQL Native Client]Named Pipes Provider: Could not open a connection to SQL Server [2].
As I understand it, the local instance of SSE is the default, and should use a local (shared memory?) connection. This seems to work for Management Studion Express, but not bcp.
While investigating this problem, I tried enabling remote connections (all types) through the Surface Area Configuration wizard, and found that remote connections using either of:
bcp eSpacePh1.dbo.UserProfile out UserProfile.txt -T -c -S localhostsqlexpress
bcp eSpacePh1.dbo.UserProfile out UserProfile.txt -T -c -S mycomputernamesqlexpress
both work ok.
Extra Info
When starting Management Studio Express, it says something like "Configuring environment for the first time". However it says this every time it is started, not just the first run after installation, does this indicate some configuration data is not being successfully stored?
I have found threads that look similar to my issue-

However these do not relate directly to bcp, and to be honest my knowledge of SSE is slender enough at this stage that i'm unsure if there are really relevant.
Any hints on how to proceed much appreciated.

Fellow Devs,
I have an instance of SQL Server Express 2005 running on another box and I have Remote Connections enabled over both TCP/IP and Named Pipes, but on my other box I keep getting the error that the server does not accept Remote Connections.
Any ideas why this might be happening? Is there some other configuration?

My site works fine in VWD2008 express, but I get this error when I try to use it on my live website.
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.
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.

I get the following error and have been trying to figure out why I keep getting it. Initially, I had placed my project under wwwroot folder and ran it under IIS and it gave this error. Then I moved it to my local C drive and same thing. I am sharing this project with two other co-workers and all our config files and code files are same...they don't get this error but I do. I checked that SQL Server Client Network Utility has TCP/IP and the 'Named Pipes' enabled. I thought maybe I have setting in the Visual Studio 2005 that I'm not aware of that's causing this problem...it can't be the server since my co-workers aren't having this error and can't be anything in the code since all of us are sharing this project through vss. I dont' think using different version of .net framework can create this error. I changed the version from 2.0 to use 1.1x and it gave same error... Any help would be greatly appreciated. Thanks in advance.
