MSSQL Server 2005 Remote Connection Problme

Nov 8, 2007




I am using MSSQL Server 2005 Express Studio and tryig to connetch to the remore server but does not work.

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.


Though I have read like child and made changes according to it.

http://support.microsoft.com/kb/914277

Still says same error.

I am clueless how to do it.

Do any one know web based mssql editor where i can connect mssql?


Thanks in advance.

ADO Connection To MSSQL Server 2005... Need Help

Oct 8, 2006

Hi,

at first a few things about my system:
I use Visual Studio 2005 Pro on WinXP SP2 and I have recently installed MSSQL Server 2005 Express on my system.

I want to establish a connection to the MSSQL Server from C++ (not .NET) using ADO.

For this I use the following connection String:

Open(L"Provider=SQLNCLI;Server=FREECASTLE;Integrated
Security=SSPI;DataTypeCompatibility=80;MARS
Connection=True;",L"",L"",ADODB::adConnectUnspecified);



This works. But this is not exactly that what I wanted, because here
just my Windows Authentication is used. I want to be able to pass
username and password for users that are allowed to access the SQL
Server. Here my first confusion begins: I have the option to pass the username and password into the connection string (User Id and Password) or I guess that I can pass them also as parameter 2 and parameter 3. But with trying both of these options I get always a connection error that my specified Username is not be trusted ( I don't know how the message looks in the English version, because I have the german version), but I suppose you know what I mean.

Of course I have to create such accounts in the SQL Server before trying to login with them. I guess that I made something wrong when doing this. I started the Server Manager Studio and there I navigated into the Object Explorer. In the folder Security I created a new account for testing (using SQL Server Authentication). But I cannot use that account for logging in.

I have to admit that I am very new to the SQL Server thing, so I hope someone can help me or can give me hints on what to do better. I am very thankful for every reply...

Remote Connection To SQL Server 2005

Aug 29, 2007

I have a software to connect the SQL Server as DB, and it is ok to connect to the SQL Server 2000 on the remote server in our firm, but got errors when doing the connection to the SQL Server 2005. the error messages are:
Error #1:
ADO Error #-2147467259
Description SQL Network Interfaces: Error Locating Server/Instance Specified [xFFFFFFFF].
Source Microsoft SQL Native Client
Error #2:
ADO Error ##-2147467259
Description An error has occurred while establishing a connection to the server. When connection to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections.
Source Microsoft SQL Native Client
Error #3:
ADO Error ##-2147467259
Description Login timeout expired
Source Microsoft SQL Native Client

I'm using SQL Server 2005 version 9.00.1399.00, not the Express version. Should I update the SQL Server 2005 Network Configuration in SQL Server Configuation Manager? But I don't know what should be set to "Enable" or Disabled". Is any other place need be configured?

Thanks.

SQL Server 2005 Remote Connection

Feb 23, 2006

This has probably been answered before, but...

I have a local SQL Server 2005 instance running, and I would like to have another user on my network connect to this instance. However, when he tries to connect, he always receives the same error message:

"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 under the default settings SQL Server does not allow remote connections. (provider: SQL Network Interfaces, error 28: - Server doesnt' support requested protocol)"

So, I checked the properties for the server, and under the connections tab the allow remote connection box is checked.

Any clue where to look next?

Slow Connection. ASP Page Querying A Linked Server On MSSQL 2005

Dec 28, 2006

Creating a web application.  Running a simple query "SELECT username FROM vwCustomer"

vwCustomer is a view built on top of an Access DB which is set up as a linked server.  Within SQL Server that view responds immediately.  But when I try to access it from an ASP page it takes over 20 seconds to respond.

Used the following to create the linked server:

EXEC sp_addlinkedserver 'DBName', 'Jet 4.0', 'Microsoft.Jet.OLEDB.4.0', 'c:databasesdatabase.mdb'

GO

EXEC sp_addlinkedsrvlogin 'DBName', FALSE, NULL, 'Admin', ''

GO

The view is simply(this works fine in SQL Server):

SELECT * FROM DBName.db.dbo.customer

The ASP page:

SELECT * FROM vwCustomer

Can anyone give me a hint as to where the bottleneck is?  Or how I can figure that out using SQL Profiler or something?

Please help!

SQL Server 2005 Remote Connection Failure

Jun 7, 2007

I'm having a big problem with a SQL 2K5 cluster (using standard edition). I can get onto the box and connect to the sql server locally fine. However when I try to connect remotely I get errors.



Let's call the two sides of the cluster, CL1 and CL2 and the "virtual server" is CL3. Locally I can connect without any problem at all to the SQL server, but I just can't connect to it from any remote machine.

The server in question is instance name LMS_PRD running on CL3, port 10051. TCP/IP is definitely enabled for local and remote connections (I have checked this in the SQL server surface area configuration). I can connect locally without any problem. Also, locally, if I do,

telnet CL3 10051

it connects fine



From a SQL 2000 box - when I try to connect from sql query analyzer, I get

"Unable to connect to server LMS_PRD Server Msg 17 ... SQL server does not exist or access denied"

Client network utility shows server alias - LMS_PRD, TCP/IP, CL3LMS_PRD,10051

[I can connect to other SQL 2005 servers OK from this same server using this same method]

On this box, when I do telnet CL3 10051 , I get "Connecting to CL3...Could not open a connection to host on port 10051 : Connect failed"

[When I do a similar one for another SQL 2005 box, "telnet U01 10051", it connects fine]



From another SQL 2005 box - when I try to register the server, I get

"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 - No connection could be made because thew target machine actively refused it.) (Microsoft SQL Server, Error: 10061)"



IN the SQL native client configuration it shows alias name - CL3LMS_PRD, server=CL3LMS_PRD, protocol tcp, parameters 10051



Again if I do telnet CL3 10051, I get the error above.



From this same box I can register another SQL 2005 server without any problem and do the telnet to it OK



Just to emphasise:

(a) The SQL server configuration manager shows that TCP/IP is enabled, and that 10051 is the port (in IPALL, TCP port). Also I have checked the SQL server errorlog - it is definitely using 10051 as the port.

(b) The SQL server surface area configuration shows under local and remote connections using both TCP/IP and named pipes selected (I've tried both this and the using tcp/ip only option)

(c) SQL server browser is running

(d) There are NO firewalls etc involved



Any help or advice MUCH appreciated

Any thoughts anyone?

SQL Server 2005 Remote Connection Not Allowed Error 26

Jan 11, 2008

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?

SQL Server 2005 Remote Connection Problem... Big Time.

Mar 17, 2006

Hi,

I installed SQL server 2005 express edition on my windows server and I had no problem with connecting it remotely through Management Studio, then I removed it and installed a full edition SQL server 2005. That's when it's gone all wrong.

Now I can't remotely connect the server through Management Studio. The error I get is the same as some of the people in this forum has which 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)"

The problem is that I have all protocols enabled and even when I disable firewall and unassign all the ip filters still no go.

I looked at te machine.config file at my server and the connection string bit goes like this:

<connectionStrings>
<add name="LocalSqlServer" connectionString="data source=.SQLEXPRESS;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|aspnetdb.mdf;User Instance=true" providerName="System.Data.SqlClient"/>
</connectionStrings>

Can anybody tell me wether you think the problem lies here where it says SQLEXPRESS where I actually have Sql Server 2005 installed.

I've been in and out of every documentation regarding this but they all tell me to configure the protocols and nothing else which doesn't really help.

I have tried running .Net Sql server wizard on the server but it didn't connect probably for the same reasons why I cant connect remotely.

I would really appreciate any help

Thanks

A Couple Of Questions On Remote Connection To SQL Server 2005 Database

Nov 23, 2006

I have a SQL Server 2005 database (called BDHSE) in a PC which i call PC1. I have a second PC (PC2) and both are within a network (a WLAN).

What i want is to have access to BDHSE from an application in VB6 (APP1) running in PC2. All the INSERT, DELETE, UPDATE records process is done through APP1.

APP1 ia currently running in PC1 and is to be installed on PC2.

I have these questions:

1. What do i need to install in PC2 since all the INSERT, DELETE, and UPDATE is done using APP1? I guess i only have to install the Microsoft SQL Native Client (with all the prerequisites of course) but i am not sure.

2. In the APP1 made in VB6, do i have to change the connectionstring since i am accesing the database which physically is at PC1 and the APP1 will be used in PC2?

3. Any advice you can give me on doing this will be well received.

Thanks in advance,

BSc Fernando Martinez

Jan 22, 2008

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.

Importing Data In MS SQL Server 2005 Using Odbc Drivers From A Remote Connection

Nov 28, 2007



hello there! i have a problem importing data from a remote connection using Sybase ASE ODBC driver(the sybase odbc driver is the only way we can access the database from the remote connection, we've already tried this in crystal reports). in the sql server import export wizard i chose the .net framework data provider for odbc. then below the wizard requires the following info: the connection string, DSN and driver. i specified the correct driver and dsn. in the connection string i specified the user id and the server name but it still produces error. the error says:

the operation could not be completed.

additional information:

Dec 10, 2007

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.

The remote connection to the device has been lost.

Please verify the device conection and restart debugging.

I used to get this problem in VS2003 sometimes and just like the numerous posts on different sites that I've looked at the problem eventually goes away and I'm none the wiser. One guy said that he found that if he went to bed the problem was resolved when he came back!

My PDA running Windows 2003 2nd Edition is directly connected to my PC via a USB port. I've rebooted my PC and done a soft reset on the PDA but it didn't help. I'm using ActiveSync 4.1.

Does anyone know how to resolve this problem?

Sql 2005 Remote Connection

Jul 30, 2006

I am having a problem connecting to a remote SQL server 2005 instance. The remote server is for a website hosting account of mine. I can connect to the server from computers other than the problem computer just fine. I cannot connect to the server using any software including SQL Server Management Studio Express, Visual Web Developer, or even when trying to use aspnet_regsql.exe on the problem computer. The request to connect to the remote server never seems to leave my computer. When talking to my hosting service, they replied that they did not receive a request to connect to their server from me. I have shut down Windows Firewall as well as my third-party firewall with no change. The error message that I receive 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) (Microsoft SQL Server, Error: 53)

If anyone has any ideas they would be appreciated.

Sqlserver 2005 Does Not Allow Remote Connection

Jan 27, 2007

I am using the VB 2005 login controls in a web application together with a wizard created sqlserver 2005 database stored in the application's appData directory. The controls work ok on my local development computer but when I deploy the application to a web hosting server (ASP.Net) I get the following error message when using any of the log-in controls:
 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)
Any suggestions on how to eliminate this error? Thanks for your help.

PHP5, Apache 2.2, MSSQL 2005 Express - Intermittant DB Connection Problem?

Feb 20, 2008

Hi all.

I've had a web service developed in PHP5 running on an Apache webserver for the last 9 months. It handles a lot of XML requests and stores/reads from an MSSQL Server 2005 DB (Express, if that matters).


Occasionally, I will come across the error 'Could not connect to database'. Refreshing the page works 99% of the time removes the error and the system continues as normal. I'd say this is happening about 1/100 requests at the moment, and my client is steadily becoming more irritated by it.


As far as I know, the system settings are mainly stock. It was set up by another developer.


I'm out of ideas with regards to debugging this problem.
Can anybody shed some light, or some possible solutions?




Kind Regards,
Jomn

I have written a database application using .mdf in visual studio 2005 using vb.net (Windows XP sp2)

The app runs fine on the local machine. But I want to access the database from another computer (remote connection)

My Questions:
1. How to host the database file (mydb.mdf) on server machine?
2. How does connection string change on the client side?

Any other idea?

THanks!!

Database Connection SQL Express 2005 Remote

Jan 2, 2008

Good day.

I am trying to look at a friends database that they have developed. Not having used SQL Server Express before I am experiencing problems trying to remotely connect to their database.

He connects locally just fine of course.

I get the error message about remote connectionsand the default settings so I have enabled TCP/IP and Named Pipes as well as cleared SQLSERVER Express in my firewall settings. I also stopped and restarted the service, but still get the same error message.

My connection parameters are like:

Server type: Database Engine
Server name: http://sql.exampledatabase.net (should http be here? have tried with and without same error)
Authentication: SQL Server Authentication (windows authentication? If so, how do I change to such?)
Login: http://username (should http be here? have tried with and without same error)
Password: password

TITLE: Connect to Server
------------------------------
Cannot connect to http://sql.exampledatabase.net

ADDITIONAL INFORMATION:
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)

Any help would be much appreciated.

Lost Connection To Remote Data On SBS SQL 2005

Aug 21, 2007

I need help!

I have Outlook 2007 w/BCM running on XP Pro workstation connecting to a SBS 2003 R2 hosting my SQL 2005 database. I have two problems: First I can get the BCM to connect to the remote data but periodically the connection is lost and many times it requires a reboot to reconnect. Secondly related to teh first, I can never get MS Accounting 2007 to connect to the same server and database from my client.

I have already set up the server to use port 5356 via TCP amd added a hole through my client windows firewall for the same port. Both client and server are set to share files and printers.

Any suggestions?

Desperately Need Help With SQL Express 2005 Remote Connection Problem

Jun 2, 2008

I have Microsoft SQL express server 2005 setup on one server and I have a website setup on another server, I am trying to get some data from the SQL server on the other one. 
I am currently getting 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.) I have done plenty of searching on Google, and already been through the tutorial on changing the setting in ‘SQL Server 2005 Surface Area Configuration’ to allow remote connections
http://blogs.msdn.com/sqlexpress/archive/2005/05/05/415084.aspxhttp://support.microsoft.com/default.aspx?scid=kb;EN-US;914277
It works perfectly when I call data from my local machine.
Also I don’t know if it is a timeout issue, because I tested in on two other servers I have access to and it worked on one of them.
Any help would be very much appreciated.
Thanks in advance.
