ASP.NET && SQL Server Express Remote Connections Problem
May 3, 2007
Hi,
My Web Aplication read and write into a sql server express database. The database is in one server and the applicacion is running from my laptop.
Everything works well.
But if i publish the web in the same server that the sql server and getting the next 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)
When am running the application from my laptop i am using the external IP and when I publish it in the same server i am changing the IP for the server name. The most interesting part is that the web can read but when it tries to insert is when am getting this error.
Any clue??' I can select, delete, insert using Microsoft SQl Server management Studio from my laptop, then the sql server accept remote connections.
I do not understand why the ASP.Net application works perfectly when runs from my computer but get this error when is publish in the server.
Any help will be more than appreciate.
Thanks in advance

Hi all,
In my office computer network system (LAN), my Windows XP Pro PC has SQL Server Express and VB 2005 Express installed and I was granted to have the Administrator priviledge to access SQL Server Express. I tried to create a SQLCLR project in my terminal PC.
1) I tried to set up a remote connection to SQL Server Express in the following way: SQL Server EXpress => SQL Server Surface Area Configuration. In the Surface Area Configuration for Service and Connection - local, I clicked on Remote Connection of Database Engine, SQLEXPRESS and I had a "dot" on "Local and remote connections" and "Using TCP/IP only". Then I clicked on "Apply" and "OK" buttons. Then I went to restart my database engine in SQL Server Management. When I went to check SQL Server 2005 Surface Area Configuration, I saw the arrow is pointing to "Service", not to "Remote Connections"!!!??? Is it right/normal? Please comment on this matter and tell me how I can have "Remote Connecton" on after I selected it.
2) After I restarted the database engine (I guess!!), I executed the following project code (copied from a book) in my VB 2005 Express:
//////////////--Form9.vb---/////////////////

Troubleshooting tips:
Store application data in isolated storage.
When deploying an Office solution, check to make sure you have fulfilled all necessary requirments.
Use a certificate to obtain the required permission(s).
If an assembly implementing the custom security references other assemblies, add the referenced assemblies to the full trust assembly list.
Get general help for the exception.
I am a new Microsoft VS.NET Express user to do the SQL Server 2005 Express and VB 2005 Express programming by using the example of a tutorial book. Please help and tell me what is wrong in my SQLCLR sep-up and project coding and how to correct the problems.
Many Thanks in advance,

My target market includes Micro-SMEs (i.e. 1 to 2 person business). This users often have multiple computers, but tend to run XP Home edition. Hence I need to set up a SQL Server Express on one of the machines and allow the other machines to access it.
So far I realise:
XP machines must be SP2ed (http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=379560&SiteID=1)
XP Home machines need to be in the same work group (am I right?)
I have to Open up the MS Firewall on each of the machines for TCP ports 1433 and 1434 (see http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=511441&SiteID=1)
On the machine hosting the SQL Server Express instance, start the "Browser" Service (again http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=511441&SiteID=1)
I have several questions surrounding this.....
If I package SQL Express with my application is there away I can get the Browser to be started automatically? Do I need to write some custom code using the Microsoft.SqlServer.Management namespace?
My understanding of the SQL Server security model is that ideally I should ideally use Windows Authenticated users connections - how do I set up the remote XP Home user on the XP Home machine which is hosting the SQL Server Instance? I'm thing I may have to used Mixed Mode and pass the SQL Server username and password in the connection string. Am I right or can I use Windows Authenticated?
Are there any more resources other than http://msdn.microsoft.com/sql/express/default.aspx?pull=/library/en-us/dnsse/html/emsqlexcustapp.asp which I should look at for help on installing an app bound to SQL Server Express?
Thanks in advance

I've developed an asp.net 2.0 web app with vs 2005 and am using a SQL Server 2005 Express database. The app works fine locally, but after uploading to the remote web server the following error occures:
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)
How do I go about granting remote connections to SQL Server Express?
Does the web server have to have SQL Server Express installed in order to run apps that utilize SQL Server 2005 Express databases?
Do I grant access locally on my machine or do I have to be on the web server to grant remote connections?
I've been using .net 1.1 with access databases for the past couple of years, so this is all new to me.
Thanks.

Hello. I have SQLEXPRESS 2005 installed on my laptop running Windows XP Home Edition with SP2. I have an application that can connect to the local instance with no problem. The other day, I tried to configure SQLEXPRESS 2005 for a remote connection from my desktop. To date, I have been unable to figure out how to do this.
I have followed the instructions posted at various locations on the internet, but to no avail. While I can configure SQLEXPRESS 2005 to allow TCP/IP connections, I have been unable to restart the server.
Here is the pertinent snippet from the error log:
<time> Server A self-generated certificate was successfully loaded for encryption.
<time> Server Error: 26024, Severity: 16, State: 1.
2006-08-14 21:02:27.18 Server Server failed to listen on 'any' <ipv4> 0. Error: 0x277a. To proceed, notify your system administrator.
<time> Server Error: 17182, Severity: 16, State: 1.
<time> Server TDSSNIClient initialization failed with error 0x277a, status code 0xa.
<time> Server Error: 17182, Severity: 16, State: 1.
<time> Server TDSSNIClient initialization failed with error 0x277a, status code 0x1.
<time> Server Error: 17826, Severity: 18, State: 3.
<time> Server Could not start the network library because of an internal error in the network library. To determine the cause, review the errors immediately preceding this one in the error log.
<time> Server Error: 17120, Severity: 16, State: 1.
<time> Server SQL Server could not spawn FRunCM thread. Check the SQL Server error log and the Windows event logs for information about possible related problems.
I have a feeling this problem is due to the way my system is configured, not necessarily how my SQLEXPRESS 2005 is configured. My laptop and desktop are connected via a wireless router, and both machines are running Norton Anti-Virus 2006. I've added sqlserver.exe and sqlbrowser.exe to the exceptions list for the Worm protection on the laptop, i.e., the server machine. There's not a setting at the router that would prevent the server from re-starting, is there?
Any help is GREATLY appreciated!

I am running a standalone WinXP SP2 system with VS 8 and SS 5 Express on it. I have been working very nicely with VB and SSCE, but I want to learn to use Sql Server 5 Express, which I also have on my system from a prior install of VS 5. I am strictly doing this as a learning experience on my own.
I have been trying to install the NW sample database into SS 5 Ex, but it is obviously not configured properly, because I am getting errors stating that the scripts cannot install because they cannot establish a remote connection to SS. So I looked up the FAQ item here on setting up for remote connections (which I am not even sure applies for a standalone system like mine). Anyway, I followed the instructions in the FAQ, using the SAC util to configure for remote connections, but it does not work. Every time I try to start the DB engine, it fails with the following message:
When trying to start Database Engine when configuiriung for remote connections in SAC:
"TITLE: Surface Area Configuration
------------------------------
The service did not respond to the start or control request in a timely fashion, you need
administrator privileges to be able to start/stop this service. (SQLSAC)
Now, I am the admin user on the PC but OK, so I selected the SAC option to set myself as SSadmin, even though this option is supposedly only for Vista users according to the dialog. Anyway, it does not allow me to set myself as SSAdmin, it returns the following error:
When trying to add myself to SQLSAC, even though it is for Vista:
"TITLE: .Net SqlClient Data Provider
------------------------------
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)
For help, click:
http://go.microsoft.com/fwlink?ProdName=Microsoft+SQL+Server&EvtSrc=MSSQLServer&EvtI
D=2&LinkId=20476"
(which help link is no help BTW, because it is not valid). And the setting does not get set, because the next time I open that dialog, I am back to being a non-admin user.
So what is the solution here? Am I going to be able to use SS 5 Ex on my PC? No matter which connection option I select, either local only, or for any of the remote options, I cannot get it to work. Am I supposed to reboot my PC after changing a setting? Or is it just not possible to run SS 5 Ex on a standalone PC like mine?
Or worse, are there a bunch of other configuration settings I must change as well? I note that, when I look in the SS Config Manager at the properties for SS Express, I see that it shows the logon option that uses the built-in account "Network Service"rather than Local System or Local Service; is that correct? BTW the browser is always running in all this.
As you may gather, I know zip nada about SS, but I am an experienced VB/VBA/VC+/FP programmer of many years, did desktop Access databases w/VB6 frontends for a lot of customers, so I am familiar with DB design etc. I just know next to nothing about backend stuff like this, other than a little with BTrieve years ago.
Any help appreciated

I have an application that will deployed on LANS running 1- 10 systems on average.
The front end is C#.net 2.0 and the backend will be sql express.
I need to enable remote connections by default because 99.5% of our customers have 2 or more computers.
I have two questions:
1) How do I enabled remote access during installation? Can I run the sqlExpress install silently and turn this on so that my users (who are very non-technical) do not have to go into surface configuration and turn on network access?
2) If I already have sql express installed (like on my development machine now) how do I enable remote access via a command line utility without having to run the surface configuration tool? I want to be able to execute a command to turn on network access so my users don't have to go to a GUI tool(Surface area configuration) and turn it on themselves. Can I use sqlcmd to turn on network access or some other command line utility that I can execute easily. Perhaps there is some type of .NET assembly that I can reference from within my C#.net application that will allow me to enable remote access? Basically How do i take care of this without making my users have to do it?
thanks in advance

Hi,
I'm having problems getting a remote connection to sql server express.
The application connects fine on the local PC (using SQL server authentication), however a networked laptop cannot connect to sql.
The PC/Laptop have been networked using the network wizard, and files on the PC are accesible from the laptop.
tcp/ip is enabled on express and the browser service is running. All firewalls have been switched off.
Any ideas?

Hello ,
The problem is that we are having Problem while making the remote Connection to the Sql Server 2005
Basically We are having a problem connecting to SQL2005 through a package remotely. when we try to connect to a remote data base, we get the following error
[Connection manager "CRA LRRS Development DB"] Error: An OLE DB error has occurred. Error code: 0x80004005. An OLE DB record is available. Source: "Microsoft SQL Native Client" Hresult: 0x80004005 Description: "Login timeout expired". An OLE DB record is available. Source: "Microsoft SQL Native Client" Hresult: 0x80004005 Description: "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.". An OLE DB record is available. Source: "Microsoft SQL Native Client" Hresult: 0x80004005 Description: "SQL Network Interfaces: Error Locating Server/Instance Specified [xFFFFFFFF]. ".
Although by running the configuration manager on the Remote DataBase System we have enable the Remote Connections through name and IP both but still it cant access it.
Please tell us the possible consequences and provide us the feedback.
I will be really obliged if any of you can provide us the feedback on it as soon as possible.
Thanking You,
Yours Sincerely,

I am having trouble with Report Manager. It seems that every day or every other day we get this 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: TCP Provider, error: 0 - No such host is known.) 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."
To fix this we open the Surface Area Configuration for the server that hosts the Reporting Database and stop and restart the database engine then open up the Surface Area Configuration for the server that hosts the Report Manger database and stop and restart that database engine along with the Reporting Services Browser.
This actually may not be the exact order that we do the stop/starts because we have tried so many different combinations (ie. stop one then start another then restart that one, etc.). Anyway, we usually keep on stoping and restarting until we can get back into Report Manager without getting the error message from above.
Does anyone have any insight as to what this could be??

I downloaded VS studio express, and created a personal website using the wizard to test drive the thing. When I hit ctr + f5 to run the sample provided, then I get this 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: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified) "
I tried disabling the firewall (Norton's firewall because Windows is disable always). Any suggestions? This is a brand-new machine, running XP sp2, just downloaded the VS studio express.
I really appreciate your inputs.

Hi,
Attempting to open a new database engine from a Windows 2003
R2 server (x64) which is
running SQL Server 2005 to my desktop PC (XP Pro) which is running SQL 2005 developer
edition.
I€™ve opened up TCP/IP and named pipes and enabled all protocols
within surface area configuration and server
configuration manager but get this€¦
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)
Is this a red-herring type message? I ask because the text
states €œthis failure may be caused€? and as far as I can see I€™ve open up my
PC to all connections.
Thanks in advance

I've got the following error from running my aspx webpages, trying to communicate to the MSSQL 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. (provider: Shared Memory Provider, error: 40 - Could not open a connection to SQL Server)
I've see and read a lot of chatter on the forum on the topic, but didn't find my solution. I have done a number of things, all of which didn't shake the error.
1) I went into SQL Server Surface Area Configuration for Services and Connections, and set Remote Connections to Local and Remote Connections, using TCP/IP only
2) Disabled Firewall
3) Made exceptions throught the Firewall for SQL Server and SQL Browser
Any other suggestions, thanks in advance.

Hello,
I am getting this error with a web service trying to fill a strongly-typed dataset stored in another project that the web service has connection to. I keep 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: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)
I set it to allow TCP/IP only, TCP/IP and Named Pipes, and Named Pipes only remote connections allowed. But it still doesn't work. I don't understand what the problem may be. I stopped and started the database engine service every time (this is a SQL Express database attached to the server, by the way).
Any insight would be helpful, Thanks.

Guys,
I can connect the sql server instance through management studio and I can also create a DSN to the same sql server instance. But when the application tries to establish the connection i get the following error
I have checked the following
SQL BROWSER is started
TCP/IP default port 1434 is enabled
At this point I am not sure how to proceed further to trouble shoot this issue.
System.Exception: 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) ---> 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)
Any suggestions and inputs would help.
Thanks

I already asked this question at the MSDN forums, but I'm asking it here because I got conflicting answers.
I want to configure my server to allow remote connections. For some unknown reason, I'm unable to do this with the Surface Configuration Tool. My understanding is that I can accomplish this using the sp_configure stored procedure. Is this correct? If so, can someone please give me an example of the correct syntax? BTW, I'm running SQL Server 2005 on winxp pro sp2.
Thanks in advance.

I downloaded VS studio express, and created a personal website using the wizard to test drive the thing. When I hit ctr + f5 to run the sample provided, then I get this 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: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified) "
I tried disabling the firewall (Norton's firewall because Windows is disable always). Any suggestions? This is a brand-new machine, running XP sp2, just downloaded the VS studio express.
I really appreciate your inputs.
Regards,
Carlos

i installed sql server express, but i did not select to use mixed mode (the reason being for this that every time i did i got a install coruption error) i want to be able to connect the database remotly using the sqlservers jdbc driver. however i need a user name and password. therefore to do this i believe i need to be able to acess the database remotly.
ive tried everthing:
1. changing the surface area remote conenctions to allow remote connections using tcp and ip only
2. restarted the database
3. restarted the server
4. restarted the browser
5. checked the tcp/ip settings are enabled.
but when i do the follwing in command line i get this:
C:>osql -E
[SQL Native Client]VIA Provider: The specified module could not be found.

[SQL Native Client]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.
which indicates that its still not allowing remote conenctions, any ideas?

Hello ,
The problem is that we are having Problem while making the remote Connection to the Sql Server 2005
Basically We are having a problem connecting to SQL2005 through a package remotely. when we try to connect to a remote data base, we get the following error
[Connection manager "CRA LRRS Development DB"] Error: An OLE DB error has occurred. Error code: 0x80004005. An OLE DB record is available. Source: "Microsoft SQL Native Client" Hresult: 0x80004005 Description: "Login timeout expired". An OLE DB record is available. Source: "Microsoft SQL Native Client" Hresult: 0x80004005 Description: "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.". An OLE DB record is available. Source: "Microsoft SQL Native Client" Hresult: 0x80004005 Description: "SQL Network Interfaces: Error Locating Server/Instance Specified [xFFFFFFFF]. ".
Although by running the configuration manager on the Remote DataBase System we have enable the Remote Connections through name and IP both but still it cant access it.
Please tell us the possible consequences and provide us the feedback.
I will be really obliged if any of you can provide us the feedback on it as soon as possible.
Thanking You,
Yours Sincerely,
Saima Salim

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?

Hi there! I've been trying for several days now to configure SQL Server 2005 to allow remote connections, apparently, with no luck.
I always have this error message: Microsoft SQL Native Client: 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.
I've followed the instructions at this link -> http://support.microsoft.com/?kbid=914277&SD=tech, but I have been having the same problems.
I've already adjusted my firewall settings.
What should I do?
Please help me...

I use ASP.NET 2.0 and VS.NET 2005.
I have the following expression in my code:
string connectionString = "server='localhost'; user id='sa'; password=''; Database='Northwind'";
When I executed the code I have 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: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)."
The Microsoft Access was successfully connected in the Server Explorer window.
How do I solve this problem?
Thanks,
Andy.

Hi guys
Apologies if this is the wrong place to be posting this but I have posted on a few forums and have not had any usable answers to this question, so I am hoping you guys will be able to help me.
I have 2 servers that are on the same domain. My ASP.NET application is running off the first which has .NET 2.0 installed, and I have an SQL Server 2000 db on the other. Whenever I try to connect 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)
The connection works when I run the project in VS Development Server on my work computer, but as soon as I upload to the server I get this error.
I have scoured Google but all of the sites I come across are for SQL Server 2005 and are just not suitable for solving the issue on 2000.
Any help would be greatly appreciated as I cannot continue my current project until this issue is resolved.
