SQL Server Losing Connection When Connection From A Remote Server
Jul 12, 2006
Hi
I have two machines, the one has Windows 2003 server and the other has Windows Xp Pro on.
The 2003 one has SQL Standard Edition 2000 on where as the XP Pro has MSDE 2000.
I'm trying to run a windows based app from the 2003 server and it connects to a database on the XP Pro PC.
When running the application i keep getting the following exception:
"A Transport-Level error has occured when sending the request to the server (Provider: Named Pipes Provider, error: 0 - The specified network name is no longer available)
After using Preformance monitor on the XP machine it seems that when the app starts and the user logins in it make a SQL connection but then the connection is lost then the exception pops up. then i click continue and try it again then it works, then a couple of secs when using the system it pops up again. The Performance Monitor Test shows that the SQL connection keep being lost. The network is fine. its has something to do with SQL and Named Pipes and stuff.
When running the app on the Xp machine and the Connection is made to the 2003 machine there is no problem.
There are other connection made to the Windows XP Machine but i doubt that it affects the app.
The Windows firewall is off as well.
Please can anyone help.

Hi, I'm working on a project that connects to a database on every view of a site. It works fine for a few hours but eventually it just stops connecting to the database. There's nothing in the application logs to suggest where to look, it seems like the connections are just dying.
I am creating the connection in a pretty normal manner:SqlCommand myAwesomeCommand = new SqlCommand();myAwesomeCommand.Connection = new SqlConnection(myAwesomeConnectionString);myAwesomeCommand.CommandText = myAwesomeSQL;myAwesomeCommand.CommandType = CommandType.Text; // Otherwise known as awesomeText
myAwesomeCommand.ExecuteScalar();
I also use a SqlDataAdapter and fill it for some of my stuff for grabbing more complex data, but all happy System.Data.SqlClient stuff.
But yeah, the thing seems to just give up after a few hours. Everything I have read about connection pooling in ADO.Net says that the connections won't be reused. And yes, I believe I am closing all of my connections after I use them. The site is getting, oh, 7500 hits an hour maybe? Somewhere around that, maybe more maybe a little less.
Anyone have any ideas?

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.

Hi,
I've worked with SQL Server plenty but never in this specific manner. Hoping someone can shed some light.I have a webform on web server A that needs to talk to a SQL server database that web server B accesses via its web application. I do not haveany privelidged access to server B or the sql server it uses (no FTP to webserver, no remote access via Enterprise Manager to the SQL server). The Admin of Server B told me that I can use a DSN connection to talk to the SQL server database that the web app on server B uses. He emailed me the names of the SQL database tables AND a copy of the web.config from server B which shows the DSN implemented like this:<appSettings> <add key="dsn" value="data source=sql3.domainname.net;database=dbname;User Id=dbuserid;password=dbpw;" /> <add key="default_language" value="en" /> <add key="error_email_to" value="someone@domainname.com" /> <add key="baseHref" value="http://www.mysite.com/" /> <add key="website_name" value="$$$$$$$$$$$$$$$$$" /></appSettings>
I was planning to run my webforms on Server A where I do have FTP, Control Panel, etc.So, I wrote this code into my VB.NET codebehind file.
Dim oODBCConnection As OdbcConnectionDim sConnString As String = _"Driver={SQL Server};" & _"Server=sql3.domainname.net;" & _"Database=dbname;" & _"Uid=dbuserid;" & _"Pwd=dbpw"oODBCConnection = New Odbc.OdbcConnection(sConnString)oODBCConnection.Open()... commands to access data and load something into a control on a webformoODBCConnection.Close()
When I attempt to run the webform in my browser from Server A. I'm getting this error:ERROR [08001] [Microsoft][ODBC SQL Server Driver][DBNETLIB]SQL Server does not exist or access denied. ERROR [01000] [Microsoft][ODBC SQL Server Driver][DBNETLIB]ConnectionOpen (Connect()).The error is EXACTLY the same whether I place the appSettings section in server A's web.config or leave them out.I have obvious questions about the error like...Might sql3.domainname.net simply be refusing communication requests that don't come from the Server B domain?Might the sql3.domainname.net be setup so that I need to use another protocol (not tcp/ip)?Might my code need to be changed to support this type of connection (i.e. I didn't code it right)?I spent some time reading http://support.microsoft.com/kb/328306/en-us but I'm at a loss as to what the best course is to take for debugging this.Thanks in advance for any insight you can offer.

I would appreciate any help anyone can offer
I am developing a web application that needs to access SQL Server. I have implemented forms authentication. My Sql server is on another machine and I am unable to connect because ASPNET is a local account. Is there a way around this, I really need to keep forms authentication and I am forbidden to place Sql Server on the same machine

Hi,
Just want to know what I need to check to make sure the remote connection is configure properly other than "Enable the remote connection" for the server? what ports that need to open up if firewall is running on the Server Machine?
I tested with a remote user, it seems the application just hung there and wait.. wait.. it seems something block the connection.
No error message, If I ping from the remote PC to the server, the response time is in acceptable range.
Thanks!

hi
I am developing a web application using C# and SQL Server 2000. It works fine when the Application and DB are in same machine. Now I want to connect to the DB located in another machine in the same network.
I used the connection string as follows.
"Data Source=ip add,1433; user id=uid; password=pwd;"
"Data Source=machine name; user id=uid; password=pwd;"
but the appliation always throws 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)"
what is the problem in the connection. Do I need any special configuration that has to applied on the DB machine.
Anyone pls give a solution ASAP.
thanks in advance

Hi, I have an issue with ASP.NET 2.0 and SQL Server 2005
My project when hosted in a machine its working, but in case of some other machine it is throwing 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)I have turned off my firewall and network configuration for sql server and its also done as tcp/ip and named pipes…though it is not working …
The surprise is if I run using IDE its running , in the same machine after hosting it is not running, where the db is in another machine. What could be the problem? Any suggestions would be highly appreciated. Regards,Naveen

I know this is strickly not a website question, but dunno where else to post...To remotely admin and monitor some functions of the website, I wish to use a local application to connect to the MSSQL DB which is held on the remote webhosting serverI have the following code: Dim StrSQLUN As String = "[UN]"
Dim StrSQLPW As String = "[PW]"
Dim StrServer As String = "[IP][INSTANCE]"
Dim StrDB As String = "[DB]"
Dim strTimeOut As String = "Connection Timeout=0;"
Dim pStrSQLConn As String = "Server=" & StrServer & ";Database=" & StrDB & ";User Id=" & StrSQLUN & ";Password=" & StrSQLPW & ";" & strTimeOut
Dim sqlConn As New SqlClient.SqlConnection(pStrSQLConn)
If sqlConn.State = ConnectionState.Closed Then sqlConn.Open()
This has basically been take from the existing code on the website, but changing to the server details. I had just started dev'ing this app when the admins decided to move the SQL server over to a different server. It was working on the old one, but the new one doesn't. It just times out after whatever time you put in the timeout variable. 0=unlimited, and so just sits there.I am also using the MSSQL Server Management Studio locally to connect to the same database, and although slow, does connect after about a minute or so. I thought they would be using the same type of underlying connection to access the server and database? Is this correct?
Can they put restrictions in place for this specific sort of data access?Does anyone have any suggestions on how to resolve this issue??Thanks for any helpAdam.

Here is my environment and problem:
I have VWD 2005 and SSE 2005 installed on my local machine. I also have these installed on my Windows 2003 Server. I developed my database using SSE on my local machine but pointing to directory on my server. I have been developing the web app using VWD on my server. I now want to use VWD on my local machine and point to the project on my server. I am able to open the project. In order to access the database in the "Database Explorer" I use as my "Data Source", "MS SQL Server (SQL Client) and it attaches fine and I can see my tables and data.
Now for my problem:
When I try to run the application "VIew in Browser", which login.aspx page is my first page, I get the page, but it doesn't inherit my master page which has the basic navigation and layout. Then after I try to login I get this message.
The file "W:BBAppApp_DataTimeTracker.mdf" is on a network path that is not supported for database files.An attempt to attach an auto-named database for file W:BBAppApp_DataTimeTracker.mdf failed. A database with the same name exists, or specified file cannot be opened, or it is located on UNC share.
Here is a portion of my web.config file for the connection string.<connectionStrings>
<remove name="LocalSqlServer" />
<add name="LocalSqlServer" connectionString="Data Source=.SQLExpress;Integrated Security=true;AttachDBFilename=|DataDirectory|TimeTracker.mdf;User Instance=true" />
My website I started with the source code for the TimeTracker start kit and have added more pages and changed the sitemap.
In general I guess I need to know how to handle using VWD on my local machine, but accessing the project on the server. The reason I'm doing this is because my colleague needs to be able to access the web app too to add pages to the site.
Thank you for any help.

hi sql team i've been reading much of the ms walkthroughs and some forum how they solve sql server 2005 (express) remote connection but non of them squared my problem.
in my case since we dont have in-house web server i need the script (ASP) run from our domain host/hoster and the sql database will be somewhere in our office. i try making a local (LAN) run of script just to test if the connection (asp-to-sql dbase) was established and im getting all things work.

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.

Server :ip address

i have a problem and it comes up with this message
"Test Connection failed because of an error in initializing provider.Login timeout expired.An Error has occured when establishing a connection to the server .when connection sql server 2005 database,this failure may be caused by the fact that under default settings sql server does not allow remote connections"
i do the same locally and it works out fine.

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 have installed SQL server 2005 express on my main server.
It has been installed with windows authentication.
I can use sqlcmd -S machinenameinstancename to connect to the server, but when I try to connect from another machine on my lan, I get the error about user not part of trusted sql connection msg 18452 level 14 state 1
I have tried using a windows username and password from my server to access it but that fails also.
Any help would be appreciated

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?

hi
i added 2 databases to my SQL server on a machine next door using Microsoft SQL server management studio express... I made sure that the server allows remote connection
then from this computer i pass a connection string to my SQLCLient in VB2005 that looks a bit like this
Code: ( text )
ConnString = "Server=USER-PTDH8Z5ESHSQLEXPRESS;Database=FSS.MDB;Trusted_Con nection=True;User Instance=True"
for which it gives me this error when i open the connection
SQLConnecton.Open()
System.Data.SqlClient.SqlException: An error has occurred while establishing a connection to the server.

Having all kinds of problems trying to establish a connection between a VB5 application and a remote server Sql Express database. The connection works fine with a user instance on my local machine. At one time I did have the remote connection working successfully using Sql Server authentication, whereby the application was passing the login and password through the connection string as so:
Provider=SQLNCLI.1;Persist Security Info=False;Data Source=<server name>sqlexpress;Database=<database name>;Uid=<userid>;Pwd=<password>;
I've been away from using this development database for several weeks. Things are little foggy from that initial effort, and I recently tried putting up a newer copy of the development database on this server from my local machine copy. That local database copy apparently didn't have authentication login/user used by the app, so I created the Login account and assigned the default database, then created the User account, referenced it to the Login account, and gave the user account a role as db_owner. Now when my app attempts to connect with aforementioned connect string, I get an error "Login failed for '< userid>'. I've redone this thing a hundred times and I still get this error. I did put a Windows Update on this server recently so don't know if that's an issue.
I could try using Windows authentication mode, but am not sure how to establish Logins/Users under this mode. Mainly, I'm don't know what the name of these accounts should be. Do you set the Windows login name up in both Login and User accounts? Below is a modified connect string I'd probably use for this mode:
Provider=SQLNCLI.1;Persist Security Info=False;Integrated Security=SSPI;Data Source=<servername>sqlexpress;Database=<database name>;
Any ideas or suggestion on things to try on either of these modes? At my wits on this and am up against the clock.
TIA ... Rick
