I am using SQL Server 2000 database in my VB.Net project.
My VB.net application is installed one two machines in different cities i.e. there are two separate databases.
First machine's IP address is say 202.33.44.55 and other machine IP address is say 203.33.55.66. Now I want to use each others databases i.e. I want to set their database group.
So that in my VB.Net's application which is installed on 202.33.44.55 I could see data of the 203.33.55.66 by just changing the connection string

Hi to all:
I always had a problem connecting to SQL Server from home using EM.
I do add a new server registration, but i always get the following exception:
A Connection could not be established to IP ADDRESS
Reason: SQL Server does not exist or access denied.
ConnectionOpen(Connect())
At the same time, I do use a utility, found at http://sql.bhaidar.net to connect to the same database and works perfect.
Is there any configuration I should do to my pc, don't know maybe some port configuration or so, to allow EM to connect to those remote databases?
Thanks in advance.
Regards

Hi there ppl,
I am having a little problem with a remote database, i created the database on my webspace mysql and i acess it with SQL Manager For MySQL and manage it fine, but i need this database for a C# application and now is where the problem starts.
I am using the following lines to connect to the remote database with no success and i dont know where is the problem, because i used many diferent connection strings and none have worked, i know that my webspace server is receiving remote connections because i can acess it from SQL MANAGER. I cant find the problem, i haved success with a connection string, but then a argumentoutofrange error about parameter count was killing me. Maybe i cant run the database on my webspace!?, but in that case why SQL Manager connects fine??, shouldnt give a error too?
Code Block
public static OleDbConnection CAT_DBConnection;
CAT_DBConnection = new OleDbConnection("PROVIDER=SQLOLEDB;DATA SOURCE=82.102.15.13;UID=****;PWD=****;DATABASE=****");
CAT_DBConnection.Open();

Hello,
I would like to know whether is it possible to administer a database on a hosted site - i.e inserting some lines, executing a query. I normally access the files via ftp connection. And so far the only way I figured I can mess around with the database is to download it and change it on my desktop PC.
Thank You.

Hi,
I have an SSIS package which runs subsequent packages in a batch. When I run the main package through command line or a SQL job and connect to a data warehouse that is on the same machine, it runs without a problem. When I try and connect to a warehouse on a remote machine (ideal configuration), it fails with this error:
Error: SSIS Error Code DTS_E_OLEDBERROR. An OLE DB error has occurred. Error code: 0x80004005. An OLE DB record is available. Source: "Microsoft SQL Native Client" Hresult: 0x80004005 Description: "Communication link failure". An OLE DB record is available. Source: "Microsoft SQL Native Client" Hresult: 0x80004005 Description: "Communication link failure". An OLE DB record is available. Source: "Microsoft SQL Native Client" Hresult: 0x80004005 Description: "TCP Provider: An existing connection was forcibly closed by the remote host. ".
This seems to happen on random subpackages and isn't always consistent.
My Master.dts.Config file has this connection info:
<Configuration ConfiguredType="Property" Path="Package.Connections[Batch].Properties[ConnectionString]" ValueType="String">
<ConfiguredValue>Data Source=RemoteServerName;Initial Catalog=DataWarehouse;Provider=SQLNCLI.1;Integrated Security=SSPI;</ConfiguredValue>
</Configuration>
Both machines have 64-bit operating system and 64-bit SQL software.
Any help would be great.
Thanks.

Hey, all. I've mainly worked with MySQL databases before. I'm working on an (old) ASP page that uses this connection string:strConnect = "Provider=SQLOLEDB; Data Source=SQL1.MYDBSERVER.NET; Initial Catalog=...; User ID=...; Password=..."
It works fine on the production server, but the local copy fails if I try to access the Products page (which uses the database), with this error: Microsoft OLE DB Provider for SQL Server (0x80004005)[DBNETLIB][ConnectionOpen (Connect()).]SQL Server does not exist or access denied./html/products.asp, line 19Similarly, if I plug the connection info into Tools/Connect to Database in Visual Studio, I get: Connection failed:SQLState: '08001'
SQL Server Error: 17
[DBNETLIB][ConnectionOpen(Connect()).]SQL Server does not exist or access denied. Am I doing something wrong? Do I need more info from the hosting provider to connect remotely? Or is the database not accepting remote connections at all?Thanks in advance for your help!

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.
tony.

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"
providerName="System.Data.SqlClient" />
</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

Hi everyone.
I need to know which are the best ways to connect to a remote SQL SERVER 2000 from inside a VB6 application. By remote I mean on a dedicated server outside my LAN that I can access by IP address.
Any opinion would be appreciated.

Error: 18456, Severity: 14, State: 16.
Login failed for user 'XXXXXX.COMusername'.
On the remote servers I enabled Named Pipes and TCP/IP and activated the Browser.
Here's what's strange: I can connect to one server but not any other.

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.
