Error Connecting To Sql Server Using Dialup.
Sep 7, 2006
Hi!
My application is working fine when i use broadband. but when i change my settings to dialup the application won't connect to sql server.
Details about project:
Connection string is IP based.
Sql Server 2000.
Framework 2.0
Sql Server is on hosting Servers.
Application will be running on any system that has internet connection.
The records that the application will fetch are not much, max 6 records in every 15 Secs.
Application is working fine on cable internet but when i switch to dialup it won't connect not even once.
dialup speed is good enough.
If you need any other detail please tell me...
Thanks in Advance.
Erphan Rajput.

I am using two windows 2000(SP4) server box for Sql server 2000(SP3a) replication wit following methods-
1.ISDN Dialup line with NT1 terminator at both end.
2.Create Dialup from one computer.
3.Create RAS with static IP Address at second computer (Dial in) for acceptance of dialing.
4.Dialing from one place to another computer and get connection by dialup.
5.I can ping only Remote IP (RAS STATIC) Address at both end.
Try to registered SQL Server 2000 from dial place or dial in place got following errors-

In DTS 2000 there was situation where I had to connect source and destination through a dialup connection (56k), where the transferring of data took me ages to finish, so it was not successful.
In SSIS 2005 is there is a solution?
Thank you
Cheers,

Hi,I need some help. I am getting this error after I complete the asp.net register control and click on the continue button. It crashed when it tries to get it calls this Profile property((string)(this.GetPropertyValue("Address1")));When I look at the stack, it is coming from my ProfileWrapper class which adds user address, city, etc.. from a class which inherits fromSystem.Web.Profile.ProfileBase. From the stack, it is calling the System.Web.Profile and crashed when it tries to open a connection atSystem.Data.ProviderBase.DbConnectionPool.GetConnection(DbConnection owningObject). I already migrated all aspnet_user, aspnet_roles, etc.. and don't get any connection errors. It is only when I try to get the profile data. This works on my pc, but throws an error on my lunarpage website.Any help is greatly appreciated.Thanks,AJAn error has occurred while establishing a connection to the server.

I have a perplexing problem. I've developed an ASP application for our internal business use. I'm getting ready to launch, but every once in a while the application can't connect to the database. The error I get 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)
We (IT and I) turned off the remote connections and it still happens. I'm afraid of launching without understanding what causes this and gettign a fix. To get it working again, we restart IIS and it works fine. I used VWD 2005 Express and it's running on SQL Server 2005 Express.
Thanks for any help you may have.Scott J.

Ok, I'm new to all this, so please keep that in mind. I've built my first asp.net site and it works fine locally, but isn't working after I upload it. The site was setup to utilize asp.net 3.5 framework automatically, but since the host uses 2.0.50727.42, I adjusted the site to utilize 2.0 framework (hopefully that worked ok). The host is running an SQL 2000 server, so maybe my problem has to do with that, since the error is saying SQL Server 2005 (which is what I have installed locally). If this is the problem, can I adjust the files in Visual Studio somehow to work with a SQL 2000 Server?

Hi All,I've written an ASP.NET 2.0 app that is working perfectly on my local machine when using SQL Server Express 2005 as a data source. To connect to Express I'm adding a connectionString in my Web.config file:<add name="libInstruct" connectionString="Server=localhostSqlExpress;Database=theDatabase;Integrated Security=True;"providerName="System.Data.SqlClient"/> I'm trying to migrate this app to our SQL Server box for live production use. I have detached the database from SQL Server Express 2005 and attached it in the production SQL Server box. Our SQL admin has created a SQL server username and password (not Integrated Security). All I have done is change the connectionString in my Web.config file to: <add name="libInstruct" connectionString="Data Source=the server IP address;Initial Catalog=theDatabase;User Id=theUserID;Password=thePassword;"/> Are there steps in the process that I am missing? I'm getting an exception when I try to connect to the db - System.Data.SqlClient.SqlException:
Login failed for user 'libInstructWriter'. Reason: The password of the
account must be changed.Thanks for any help you can offer! Thom CoxMedford, MA

I`m new to posting to this group so please keep that in mind while I
fumble through my explanation of my problem.
I am building an operational data store and have a staging server where I
encountered the following sequence of events. I need help in getting back
to square one.
- This server has Win NT 4.0, SQL Server 6.5 with service pack 4, and
Informatica PowerMart 4.04 on it.
- While using PowerMart to transform some data either SQL Server or Informatica
locked up and Informatica gave message it could not communicate with the
server.
- I could not connect to server using SQL Enterprise Manager. Thinking that I
might have run out of user connections I stopped the Informatica and SQL Server
services and then restarted SQL Server in a
minimal configuration mode. I used sp_configure/RECONFIGURE to increase
the number of user connections and was then able to connect to the server
but couldn`t do anything because I got a `not enough memory` error. Again,
I used sp_configure/RECONFIGURE to increase memory.
- At this point, trying to connect to SQL Server with Enterprise Manager
gave me a `cursor is not open` error. I couldn`t find anything about this
error in Books On Line.
- Knowing that I had to re-install SQL Server eventually (wrong sort order)
I attempted to remove SQL Server before re-installing. The removal process
was interrupted and did not complete normally.
- I deleted the C:Mssql.. directory and then attempted to re-install SQL Server
using the BackOffice installer. Installation seems to be fine until the very
end where I get an error that it can not connect to SQL Server and it fails.
- I have no option to remove SQL Server and can not get past the failure
to connect to server error at the end of the installation process so what
options do I have to get SQL Server back?
Thanks in advance for any help you can give

Hi all,
I am trying to connect to the server and i got this error:
TITLE: Connect to Server
------------------------------
Cannot connect to HSTSQLEXPRESS.
------------------------------
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: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified) (Microsoft SQL Server, Error: -1)
BUT when i tried to connect to the server using the name instance (local) or my computer name directly it works.
I have to use this format in the name instance while i am connecting to the server :
computerName/SQLEXPRESS
what is the problem and how can i fix it?
thanks in advance!

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'm a newbie who is trying to create a connection to the server in my website application and I keep getting the following error: An error has occurred while establishing a connection to the server.

Hi,
I am getting the following error when i am trying to connect to the database server installed on different box.
"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)"
When i searched google, some postings suggested to enable the TCP/IP and Named Pipes Protocols from SQL Server configuration Manager. I did so and also ran mofcomp command. But even after doing this i am not able to connect to the server. Following is my connection string.
<add key="conn2" value="Data Source=xxxxxxxx;Initial Catalog=xxxxxx_xxxxxx;User ID=xx;Password=xxxxxx;"/>
Could any one please tell me what else the configuration settings i need to do in order to connect to the database from my application.

Hi..
I have been assigned to make a database in some remote machine.The machine has MSSQL 2005.I need to connect to that remote machine's sql server via my pc using my SQL Management express.I do have that computer's IP address(say,123.456.789.000),and the username and password.But when i try to connect to the server ,I get the following error:
Cannot connect to 123.456.789.000sqlexpress
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 unser the default settings SQL server does not allow remote connections,(provider: SQL Network Interfaces,error:26-Error Locating Server/Instance specified)(Microsoft SQL Server)
I am a new programmer and dont know much.But i guess the problem is not in my server but in that server to which i am trying to connect.I guess that server has some instance created or it does not allow remote connections.But i am not sure.Is it so?Or is anything wrong in my server.Any ideas?
Thanks

I do hope someone can help
I have a windows server with SQL Express, I have followed the link here and still no luck
http://blogs.msdn.com/sql_protocols/archive/2007/05/13/sql-network-interfaces-error-26-error-locating-server-instance-specified.aspx
I have checked and checked again a thousand times
I can remote desktop and connect through SQL Management Express, but when I try this on my local machine I get the error 26
My knowledge is very limited and could do with some expert help
PS EDIT
I read somewhere that in TCP/IP properties all IP's should be set to 1433, is this correct
at the moment, apart from ALL IP which is set to 1433, IP1-9 are set to Dynamic Port =0, should I be setting all these to 1433
??

An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this
I use Microsoft Windows Vista Home Professional
I have already installed to my computer Microsoft SQL Server 2005 and SQL Serves Express. I used to be successful to connect to the SQL Server but now I CAN NOT.
Not: I try to run SQL Server 2005 but I can not, even I logged on to my computer with an administrator rights. On the other hand I can start and stop the SQL Server Express easily.
As a result, how can I solve this problem.
Thanks in advance.

Hi,
I've been trying to fix this error for two days! and I really need the advice of the experts please!
Computer XP Professional Service Pack2, SQL Server 2005 and Visual Studio 2005 (both Standard Edition)
ConnectionString:
<connectionStrings>
<add name="MyConnectionDB" connectionString="Data Source=(MyServerSqlServer2005);Initial Catalog=MyDB;User ID=sa;Password=PasswordforSA" providerName="System.Data.SqlClient" />
</connectionStrings>
C# code
string myConnectionString = ConfigurationManager.ConnectionStrings["MyConnectionDB"].ConnectionString;
SqlConnection myConnection = new SqlConnection(myConnectionString);
myConnection.Open();
Here I get 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: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)"}
What I checked so far:
ServerName and Instance Name OK!
Database, Username and password OK!
SQL Server 2005 Surface Are Configuration - Remote connections using both TCP/IP and Pipe Names OK!
SQL Configuration Manager - Protocolos Enabled (TCP/IP, Pipes, shared) OK!
SQL Server Browse running and active OK!
Am I missing something? I never had this problem with SQL Server 2000 and Visual Studio 2003.
Thanks in advance for any help or suggestion you can give me.

I'm new to using VS2005 and this is my first project connecting to our MS SQL 2000. App worked fine on my dev PC, connection to the same MS SQL Server. Published the web site to the web server (same server running MS SQL Server) and getting the below error. Is this a permission setup problem on SQL Server or does it really think it's connecting with a MS SQL 2005 database?

My environment is Windows Server2003, ASP.NET 2.0, SQL Server 2000 using SQL authentication (names of DB's, sql id's, passwords are identical on both servers)
My web application successfully connects to my database the web app and the DB are both on the same server (10.144.25.9).This connection string works:
<add name="DefaultDataTierConnectionA" connectionString="Data Source=10.144.25.9,1433; Network Library=DBMSSOCN; Initial Catalog=9D_SQL; User ID=******; Password=******" providerName="System.Data.SqlClient"/>
PROBLEM:
The problem occurs when the DB is mpved to the remote SQL Server (10.144.25.10). I use almost the identical connection string except for the IP address which is changed to the remote machine. The db name, user, password is same on remote machine as on the local, so everything should work but does'nt. This connection string fails:
<add name="DefaultDataTierConnectionA" connectionString="Data Source=10.144.25.10,1433; Network Library=DBMSSOCN; Initial Catalog=9D_SQL; User ID=******; Password=******" providerName="System.Data.SqlClient"/>
error (odd error in that I'm connecting to SQL 2000?) -

There is no DBA on this project, I'm not sure this is a SQL Server set up problem?

I'm experiencing a problem connecting to a SQL 2000 server through my ASP code. My connection string is as follows:
<add name="TheConnectionString" connectionString="driver={Sql Server};provider=MSDASQL;server=10.0.1.42;database=dbname;uid=*********;pwd=*********" providerName="System.Data.Odbc" />
The problem doesn't occur when I run my ASP code from my workstation using VS.NET's builtin webserver. It makes the connections and executes the CRUD commands successfully. However, when I publish my site to the webserver (which resides on 10.0.1.16) it fails out with the following error:
System.Data.Odbc.OdbcException: 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()).
I've verified that the webserver can talk to the DB server by connecting to the remote DB server through SQL Enterprise Manager running locally on the webserver. If I try to do this with a DSN I get the same results. I get the same error from any other webserver on the internal network. The difference between my workstation and the internal network is that I'm using a VPN to connect to our internal network while the webservers are physically connected to it. Firewalling isn't the issue in this case because the webservers and DB server are on a trusted network. I've seen other ways of connecting to the DB server including using Named Pipes (which I would rather not do because I don't want to setup a named pipe on the production db server).
I'm relatively new to ASP.NET 2.0, so the above connection string is an adaptation of some old ASP code. If anybody has any suggestions on a better way to construct this connection string, please let me know. I've been racking my brains trying to get this to work outside of the devel env.
