My hosting company 1and1 doesn't allow remote connection, is there a string that I can put into my web.config file to get around that? I have tried changing ports 1433 to 1434 etc but nothing seems to work. Please help.....
View 1 RepliesI created a web Appplication using Visual Web Developer but when a placed the application in the ftp and I tried to register appeared this message:

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 made some changes in the web.conf file but I still got the same message, Please can you help with this.
Thanks in advance...!
Developed a website using VS.net 05 which connects to a SQL 2005 server for its data. When I ran the site in VS for testing it works correctly. After I used the copy utility and placed the site files on our web server (seperate from our SQL server) and navigated to the site recieved the error.
Checked and verified that a data connection can be made from the web server to the SQL server
Verified that the HTML connection string was correct in the asp files.
Verified that SQL Server Browser was running (had to start it)
Verified that IIS had NP and TCP/IP enabled.
It would appear that the problem still resides in the application as a data connection could be made from the web server to the SQL server but as this is my first web app launch am wondering if I am missing something else.
Thanks,
Hi,
I have deployed my ASP .NET 2.0 app (with a SQL Server Express 2005 database located in the App_Data folder) to my production (shared hosting) server. The issue I am having is SQL Network Interfaces error as described at this URL:
How to fix SQL Network Interfaces, error: 26
http://aquesthosting.com/HowTo/Sql2005/SQLError26.aspx
After requesting the above resolution, my hosting company said:
---------------------
The raw data for the database (.mdf file) will not generate the desired results. This database will need to be restored on the SQL server to get the desired and correct results. You will have to upload the backup of the database in order to restore the database on the SQL server.
---------------------
I have never deployed an application with sql server express before, but I was under the impression that I would not have to restore a copy of the database on the server. I have read the post on SQL Server Express and Hosting (http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=2893587&SiteID=1) and see that it is not recommended in a shared hosting environment, but does this mean it won€™t work? This is a really small site where a full-blown sql server db would be overkill.
My question is: is what my hosting company stated true, or are they able to resolve the issue by following the steps found in €œHow to fix SQL Network Interfaces, error: 26€? article?

I am creating my first .net site. You can see what I've got so far at www.palmbeachatpickwick.com. It's hosted on GoDaddy and I am using Visual Web Developer and SS2005Express to develop. Trying to get the membership piece working, and I think I am about half way there, but hit a wall. The db connection works insofar as you can join the site and the new user record is successfully added to the db. The confirmation email is successful. The part that's broken which generates the error: 26 message is the page redirect after clicking on "continue". I also get this error when trying to login. Both my login.aspx and join.aspx pages redirect onsubmit to Default.aspx as follows:
After creating an account and clicking continue: ContinueDestinationPageUrl="~/Default.aspx" After logging in: DestinationPageUrl="~/Default.aspx"
There's just a few lines of text on the default page. My master page (used by default.aspx) only has a sitemap data source. No sql data sources specified. So not sure why I am getting a sql error.
FYI, I've posted the code from my web.config and master page file (minus the xml declaration and connection string username and password) here:http://www.palmbeachatpickwick.com/PalmBeach/webconfig.txt
Any insight would be greatly appreciated.
Hello All,
We are migrating from ASP.Net 1.1 to 2.0 and have built a new site with the 2.0 membership controls (Login, etc). We're using VS2005/SQL Server 2005. All works well from the development site but once it is deployed from our local machine to our intranet development server, the following error is encountered after the user types in a valid username/password and clicks the Login button (on the Login control on the Login.aspx page):

I have 2003 server installed on my machine along with MS SQL Server Management Studio and I am able to connect fine to SQL 2000 Instances. On my laptop running Vista Enterprise, I can not connect to these exact same instances via MS SQL Server Management Studio as I am getting the above error. Does anyone else have this problem? I have no idea what to check for anymore. Thanks in advance.

Ok can somebody please explain to me why only 1/2 my project is getting this error. I am working with SQLExpress on a remote windows 2003 box. The sql server has its service running and the browser is also running. The server has been set to allow remote connections and to accept TCP/IP and Named Pipes. Now, the website uses asp.net membership and roles to allow the users to login, which actually works. So I know that there are no errors in that connection string. However, all the data acess code is compliled as a sepeate class library thats referenced in the bin directory. When calling those methods to beind to a control in code, is where i run into this error. The class library connection string in the app.config file is exactly the same as the connection string in the web.config...i have checked permissions as well, im at a loss to the reason why this is not working....its probably something simple, but im not finding it.
On a seperate note - How do i get the remote database to show up in the server explorer on vs2008, i have tried putting in the ip addressinstance name, and a combo of there items, it will not connect. I have a feeling the two issues are connected. Also fyi, on the remote box, I am able to login with the sql studio express, so im not really sure exactly wuts gong on. Both items are really important and i need to be able to use both of them.
Thanks,
Jeremy
Hello, I have deployed myWebApp on the IIS. All went well now, but the site does not have any connection with the database. I've already done a search on the error 26, which gave me alot of hints about solving the problem.Still I'm gettting this error. I already enabled the remote connections through the sql surface area configuration.Could it have something to do with the fact that I use LINQ? I can't find any connectionstring to modify anywhere ... Help would be appreciated.

I made a simple ASP.NET 2.0 Website that uses memberships, roles, and access to MS SQL Server 2005 database. Everything works fine on my development computer (WinXP Pro). When I deployed this Website on another computer (WinXP Pro) and tried to access the main page from the same computer, I get the error below.
I disabled the Windows Firewall (the only one I use), I ensured that SQL Server Browser is Active and Running, and I changed Remote Connections in SQL Server 2005 Surface Area Configuration to use Local and Remote connections for all the components.

<connectionStrings><add name="sqlConnString" connectionString="Data Source=.SQLEXPRESS;AttachDbFilename=|DataDirectory|DBdemo.mdf;Integrated Security=True;User Instance=True" providerName="System.Data.SqlClient"/></connectionStrings>

Hi,
I have been stuck up with this error.
I am using SQL Srver express edition with asp.net 2.0 on windows XP SP2.
When I open the SQL Management studio and execute queries it works fine.
When I exute query in command prompt using SQLCMD -E -S ServernameInstance
It conect with database and I can freely execute queries in command prompt.
I have also tried to connect with Classical ASP 3.0 It also works fine. No error
I have made all changes that u specified in ur article.
But When I try to connect with asp.net. It gives me error.
"provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)"
Same files are workign fine in my office with SQL Server 2005 enterprise edition and ASp.net 2.0. on Windows server 2003. I do not get this error. But at home I am facing this problem again and again.
This problem happens on this particular machine and doesn't happen on other machines that I have. And I think this problem belongs to this forum. Because the problem is triggered by a special setting in the connection string.
I followed the steps of threads including Xinwei Hong's instruction for fixing this error(26) but has no luck.
The problem occurs when I call SqlConnection.Open().
I am using window xp, sql2000. the named instance is on local machine, my connection string is like
"Data Source=MSL-1417762\SQL2000;Initial Catalog=PopulateForeignKeys_MSL_1417762_2_5984;Integrated Security=True;Pooling=False;Asynchronous Processing=true"
Whenever I change Asynchronous Processing=true into Asynchronous Processing=false, the problem is gone.
This problem also occurs when I use Visual Studio - Server Explorer - Add Connection dialog - Advanced button - Advanced Properties window where you can set Asynchronous Processing property to true.
Can you please help?
Thanks,
I'm having an issue when moving my site from my laptop that's running VWD Express and SQL 2005 Express to my production Windows 2003 server running SQL 2005 Standard. The site is a portal site that authenticates to my Active Directory, and uses roles bases in SQL. I can open the site on the laptop and everything works fine and I have no problems. Once I copy the site to the production server and try to access the site, I get the login page fine and try to login. The default page never opens so I'm thinking this must be some type of roles issue. Do I need to do anything with my ASPNETDB.MDF file to make it work with SQL 2005 Standard instead of Express version? I've already made sure that the SQL server is accepting remote connections...what other things do I need to do to my SQL server to ensure proper functioning? Any particular security user I need to be running particular services under? Thanks in advance...

Hi, I have installed SQL Server 2005 and Visual Studio 2005 in my machine.
I got an error when I tried an example.
"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

I followed many advice online and did the following but still wrong.
Enable networking protocols during managment configuation.
add port 1343 on firewall or turn off the firewall.
make changes in web.confige as

I am trying to use the visual studio for database professionals. I get the error 26 when I try to import a schema from an existing database. I am using a database from my local instance. I test the connection and the test succeeds. What is causing the error 26?

I have SQL 2005 standard edition (64) installed on Win 2003 (x64) as the database server. (dbserver machine)
Despite setting up:
Remote option under surface configurator,
TCP settings under configuration wizard,
No firewall,
I am still getting the same message when I try to connect from the application server using the SQL manager. I can connect to the server on the dbserver machine but not remotely.
I have read through the threads in the forum and applied most recommendations without avail. Please help.
Thanks

View 2 Replies View RelatedHello all,
We have a Windows 2003 Web Edition server serving a site through IIS. It connects to a Windows 2003 Standard Edition server running SQL 2000 SP3a.
This site receives the following error as seen in the topic:
[DBNETLIB][ConnectionRead (recv()).]General network error. Check your network documentation.
We've configured the server network utility to only allow TCP/IP connections. The connection string for the site is as follows:
<%
' FileName="Connection_ado_conn_string.htm"
' Type="ADO"
' HTTP="false"
' Catalog=""
' Schema=""
MM_connSpankMSSQL_STRING = "Provider=sqloledb;Data Source=SERVER_IP,1433;Network Library=DBMSSOCN;Initial Catalog=ourmaindb_1;User ID=ourmaindb_1;Password=hotcookies;"
%>
Any ideas or tips on solving this issue? We've noticed it is due to larger queries as smaller ones do work with no problems.
The servers are behind a BSD box running iptables, has 1433,1434 along with standard web ports wide open. Anything outbound is allowed.
Some further testing via ODBC on the IIS server improved things. No more connection pooling for the SQL Server driver allows for 1/3 of the query to run. Still 2/3s of it doesn't show up, and that general network error message appears.
Should have 330 rows if it works right.
Hi
While running a DTS, many times the error message: "[DBNETLIB][ConnetionWrite (WrapperWrite()).]General network error. Check your network documentation." appears.
Does somebody knows why?
I am running the DTS from a computer (not the server where the DTS is stored) and it is connected without any problem when this happens.
Thanks!!

Hi Every one,
I am using .Net 1.1 for my web application.
And my database server is SQL Server 2005.
My application is running fine, as i can login to it and also able to view pages. But when i open Order management(having 3K records) its give me error,
General Network Error. Check your network documentation
I have also searched many articles and tried following solutions but nothing working
- connectiontimeout = 0, max pool size = 7500/100, pooling = false
- SSL disabling enforce security false as mentioned in microsoft kb article.
And there's nothing any issue with hardware/firewall as my application's login and other forms are working fine(which use same database with same connection string)
Can any one please help me to solve this error?
With Regards,

I use sqlclient to connect directly from my mobile 5 pocketpc to a sql server 2005 database on my desktop.
I use a sqldatareader to traverse the results of a query that delivers 2 fields: (1) the filespec, and (2) the image field.
I use a filestream with a binary writer to write the contents of the image data to the pocketpc's storage card.
I have a test table with 10 images, not one more than 4 MB. I cannot complete a test run prior to receiving the general network error.
The pocketPC is connected via activesync to the desktop, and I connect to the database with:
Integrated Security=false;
user id=sa
password=admin.
Any help with this strange error would be greatly appreciated.

First-time poster (and very new to ASP.NET, so please be patient) - I am using VS 2005. I have an ASP.Net 2.0 app that is using Forms Authentication and a Login server control with AspNetSqlMembershipProvider. I have an instance of ASPNETDB.MDF in the App_Data directory on my local machine and all works well (or at least as expected). I used the Copy Web Site function to port the app (including the ASPNETDB.MDF files) to my production platform, where I encounter the error mentioned in the subject line. I have found posts (both here and other forums) that mention enabling TCP/IP using Surface Area Configuartion Utility, SQL Server Browser are exempt from firewall, and a few other things. My production machine does not have SQL SVR 2005 installed nor SQL SVR Express. Do I have to install SQL Server Express onto my production platform in order to resolve this, or is there another means (something in SQL Server 2005 Management Studio on my local machine) that will enable me to do this on the production machine?Also, I have been told that it is possible to use a database on another machine as the data store for authentication. Does anyone know how to do that? This would make the first question moot.Thanks in advance!
