Connecting To Remote SQL Server Over TCP/IP Using ODBC
Mar 27, 2001
I was wondering if anyone knows how to connect with SQL Server over TCP/IP using ODBC
I tried using the IP address or domain name of the remote machine, but I get the following error:
Microsoft SQL Server ODBC Driver Version 03.70.0690
Running connectivity tests...
Attempting connection
[Microsoft][ODBC SQL Server Driver][TCP/IP Sockets]General network error. Check your network documentation.
TESTS FAILED!
Thanks in advance

I'm currently trying to access data from a Cache DB using MSSQL. I havelinked the Cache server through an ODBC connection. I can see in the LinkedServerexpansion all the tables in Cache for the File(?) I want to access.Here is my problem: Normally to access a linked sever I would do thefollowing:select *from ServerName.DatabaseName.dbo.TableNameI have triedselect *from ServerName.DSN.dbo.TableNameselect *from ServerName.DSN.SQLUser.TableName ("SQLUser" is the owner in Cache)None have worked (error no such object...)What is the syntax to select data on a linked sever via an ODBC connection?In the Linked server set up I have also check the RPC and RPC Out options...My ultimate goal is join tables in Cache and MSSQL into MSSQL.Any help would be greatly appreciated!Thanks,-p

Hi
I've got a desktop and a notebook and both are connected to the router. On both I've got Sql Server Express and Sql Server Management Studio Express installed. I need to connect to a remote Sql Server (using user ID and password) which works fine on my desktop, but fails on my notebook: Error:0 and Error: 10060.
I checked all router settings and notebook settings, but I don't know what I am doing wrong. I got myself another notebook and installed Sql Server Express plus Management Studio, which did not work either.
Hopefully someone can help.
Thank you.

I have recently taken over as webmaster at my company and need help connecting to our remotely hosted SQL server. The company who is hosting it will charge me "support time" to explain how to connect to it.
The database is used to store data and application information for our customer service center. So it is ALL database driven...
i have installed SQL Server Enterprise Manager on my machine, but have no ideas on where to even being trying to connect. I have the name of the server, password....etc. But do not know where to configure a connection.
ALSO, when i install my Enterprise Manager the first options askes me whether i want to create a new instance of SQL server on a local or remote machine....i am guessing my local machine right...??
any insight or direction is greatly appreciated.

I am trying to connect to a Oracle 9i Server to execute a sql task, but the connection when tested seems to fail with the following error from the Integration Services Project:
Test connection failed because of an error in initializing provider. ERROR [NA000][Microsoft][ODBC driver for Oracle][Oracle]ORA-12541: TNS:no listener
ERROR[IM006][Microsoft ODBC Driver Manager] Driver's SQLSetConnectAttr failed
ERROR[0100][Microsoft ODBC Driver Manager] The driver does not support the version of ODBC behavior that the application requested (see SQLSetEnvAttr).
The connection was configured and tested from Oracle's SQLPlus session. Please note that the port that the TNS Server is listening is not the default. Is there somewhere I can specify the port in the SSIS connection manager to resolve the issue.
I have tried OLEDB connection and that does not work either.
Any inputs will be appreciated.
Thanks,

Hello
I wrote a web app (vb.net) with mssql 2005 express edition DB.
I created a vs2005 setup project and added it to my app solution.
On my local computer it works fine (using IIS 5.1).
Now, I'm trying to deploy the app on a remote server (with mssql 2005 express edition installed) but when I try to run my app via the remote server's IIS, I get this Error message:
ERROR: Could not connect to 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: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server).
My app connectionstring looks like that:
<connectionStrings>
<add name="SiteSqlServer" connectionString="Data Source=localhost;AttachDbFilename=C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLDataMaxinet.mdf;Integrated Security=True;User Instance=False"
providerName="System.Data.SqlClient" />
<add name="MaxinetConnectionString" connectionString="Data Source=localhost;AttachDbFilename=C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLDataMaxinet.mdf;Integrated Security=True;User Instance=False"

</connectionStrings>
<appSettings>
<add key="SiteSqlServer" value="Data Source=localhost;AttachDbFilename=C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLDataMaxinet.mdf;Integrated Security=True;User Instance=False"></add>
Can anybody tell me what I'm doing wrong and how to fix it

Hey guys, I am new to the SQL server scene and I am having some trouble connecting to a remote SQL Server with SQL Server Management Studio Express.

Can anyone at all point me in the right direction or somewhere that I might at least find the answer? I appreciate any help that can be provided.
Thanks a bunch,

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 have set up a SQL Server 2005 to use for testing before moving to another production server. The server works fine when I connect to it with a program on the same computer but not when accessed remotely.
I have set it to to allow remote connections and use TCP IP only and have opened TCP port 1433 on the Windows XP firewall and am using the Teredo service on Port UDP 3544 Also the Server Browser service is running. The server is connected directly to the internet on a static IP (eg. 67.156.18.167) I have set the server to Windows authentication.
When I try to connect to the database from a data grid in Visual Studio on another computer it fails.
I am pretty surethat the problem is that I am not giving the correct information when asked to fill in the information for the data source to find the server as I am new to remote connections in SQL Server.
Thanks for any insight

Hi,
I've written a piece of database software in Visual Basic (Visual Studio 2005) to use in my office. My office has networked computers all connected to a server (windows server 2003). I have an old-ish version of SQL server on the server computer (version 7). The software works perfectly within the office environment - each computer on the network connects to the SQL server on the server computer and works very efficiently.
I now want to be able to access the database from home by running the software on my home PC. I want the software to somehow connect to SQL server in the office over the internet. Having read many of the threads about remote SQL server connections, I feel totally out of my depth. I vaguely understand that SQL server needs to be somehow configured to receive connections from the 'outside world'. I don't know how to do this. I also don't know what I need to do on the Windows server to allow this to work. I thought I might be able to use the computer's IP address in the connection string, but using IPconfig on the server I only get network IP addresses - the server may be behind a router... How do I get the proper internet address? Once I've set up the server side to work with remote connections, how do I get my software to communicate with that server? Do I just need to change the connection string and that's it? What would the format of the connection string be?
I'm very sorry for asking so many questions in one go! I have ended up a bit frustrated after reading many threads and articles about SQL remote connections - it's all rather advanced and don't understand most of it!
Thank you very much in advance for any help you can provide.

Hi,
I can connect to a remote SQL server with ADO.NET but not with OLEDB.
I get
------------------------------
Test connection failed because of an error in initializing provider. Login timeout expired
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.
Named Pipes Provider: Could not open a connection to SQL Server [233].
------------------------------
Through the SQL Server Connection Manager, if I disable Named Pipes and enable TCP/IP, I get for OLEDB connection:
------------------------------
Test connection failed because of an error in initializing provider. Unable to complete login process due to delay in opening server connection
------------------------------
with Connection and General Timeout are both 0.
Appreciate the help

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?

I'm using Visual Studio 2005 Pro and am attempting to connect to a remote SQL Server 2005. I have the server name, SQL login credentials, and database name. However, when I try connecting 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. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)"
I know that remote access is enabled because I received the connection instructions directly from the database administrator. I've tried turning off my firewall. I've tried connecting with Data source: Microsoft SQL Server using both Data providers: ".NET Framework Data Provider for SQL Server" and ".NET Framework Data Provider for OLE DB". Nothing seems to work.
Any suggestions for what I may be doing wrong? Do I have to have certain software installed on my computer to make this work (other that VS2005)?

I looked at many different sites to find a solution for this but without any luck. I am sure someone would have seen this issue here and I expect them to shed some light.

I am having a problem while connecting to a remote sql server through VS.NET 1.1 , an asp.net application. It says :"SQL Server does not exist or access denied".
I have connected to the same server from my home using the same connection string through an asp.net 1.1 app.. So it cant b a prob with Server permissions. I can connect to the same server frm my office through asp.net2.0 app.. So its got nothing to do with office permissions.
I need this connection from my office from asp.net1.1 app 2 debug n find solution for a bug as im unable to simulate it here.
Will this be smth to do with .net installation, some security enabled in vs.net.. I have no idea.. Please help me at the earliest..

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?) -
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.

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.

I'm trying to connect to a sql server machine from another machine on the network and I'm 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: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)"
More information about the machines:
All machines are on the same private netwrok, all in the same workgroup.
Machine1: this is the DB server, Win 2003 server, it has SQL 2005 developer edition, .Net runtime 2.0.
Machine2: trying to connect to machine 1, Win 2003 server, .Net runtime 2.0
On the DB server, TCP/IP is enabled with port 1433, also named pipes are enabled.
I checked the ERRORLOG and it says it's ready for connections and it's listening...Also there are no firewalls between the machines, I also added the sql server service .exe and the sql explorere .exe to the windows firewall exceptions on the DB server (although it's disabled)...
I'm not sure what else to do, I checked all sources online, applied anything related to this issue but not luck. This has wasted 3 hours of my time, this was a task that wouldn't take you a minute in older versions!! , Microsoft thinks it's making our life easier but in fact, I spend more time now on trouble shooting than before...
Let me know if you have a solution..
thanks,
