Connection to SQL server 2008 fails randomly

  
I'm sure a lot of you have seen this error: "A network-related or instance-specific error occurred while establishing a connection to SQL Server" Normally I would assume that this would mean that there's a problem connecting to the SQL server, but currently I'm having a hard time figuring out what the problem is and how to fix it The problem only occours randomly, but mostly it is when I from the same computer calls the server several times for example like this: For i as integer = 0 to 500 OpenConnectionToSqlServer(Bla bla) ReadData() CloseConnection() next I always makes sure to close the connection again. The more often I connect to SQL server in a row, the higher is the percentage of errors I have created my code so that if the above error happens, the program will wait for a second, then try again (after 3rd try it will stop trying)   I have several times been monitoring the SQL server at the same time, but I can't seem to see anything from there :(

Connection to Exchange Server of .NET 1.1 Framework application on Windows 2008 64-bit

  
I am running Visual Studio 2003 .NET Framework 1.1 application on Windows 2008 64-bit machine. There is only one problem - connection to Exchange Server. The same application is running fine on Windows 7 64-bit machine (not server). I tried to use the same Interop.MAPI.dll I used for Windows 7, but it doesn't work for Windows 2008.   Please help.  

Remote Connection to SQL Server 2008

  
Hi everyone,    I'm allowing remote connections, have started the SQL Server Browser, and have the TCP/IP protocol enabled for my server instance, but I still can't connect to my SQL server remotely.   I have my router forwarding to the local IP for it when using port 1433 and it works when I put the router ip with 1433 locally, but it gives me an error when I try this remotely. It throws a timeout error, so it isn't even reaching it.   Any suggestions?

how many open connection is recommended to leave - in sql server 2008 Enterprise Edition

  
hi i have my C# program that work with sql-server 2008 Enterprise Edition i have 40 users that connect to this database. i dont close the connection. how many open connection is recommended to leave ? or is it better to close connection ? thank's in advance

Framework 2.0 changes - TCP Provider, error: 0 - An existing connection was forcibly closed by the r

  
If you connect to a server and open a query in SQL Managment studio (2005) and looses connection and then regain the connection, when you try to run the query it gives me a "TCP Provider, error: 0 - An existing connection was forcibly closed by the remote host."
 
This happens against both 2005 and 2000 servers.
 
If I re-run the query it works.
 
However, this happens in our VB.NET app as well for clients with Wireless connections.
 
So, something has changed in Framework 2.0 regarding this, does anyone know how to tell the client to not throw this error and just try connecting the server instead which will work?
 

Connection string to connect with Sql Server 2008.

  


Hi,

May  be it's a wrong place to ask the following question. Sorry for that. Our hosting provider has recently upgraded their database server from Sql Server 2005 to 2008 and I'm getting errors to connect with remote server from my development machine. Error Message "Invalid connection". Tried to find solution on net but couldn't find it.

I'm using .Net 1.1. Though we've updated versions 2.0,3.5 & 4.0 but due to some certain circumstances I've no way to update it. It's a web based project. The following connection string works fine for Sql Server 2000 & 2005 but not for 2008.

<add key="ConnectionString" value="Data Source=Remote Server's domain name;Initial Catalog=database name;User ID=user name;Password=surround;Persist Security Info=True;Pooling=false;Connect Timeout=45;" />

Here

Remote Server's domain name indicates to remote db server like: test.mysite4now.com

database name for example: test_surround

user name like test_surround

password: surround.


Can anyone inform me what's wrong with the above connection string to connect to Sql Server 2008.

Esonix


VBScript ADO Connection In Windows Server 2008

  

Hello,

Hoping someone can help me with this one...apologies if I am in the wrong forum.

I have a small VBScript snippet that I can run on my desktop (Win XP 32bit) without any issue.

I'm now ready to put this code on our Win 2008 R2 server that runs scheduled jobs.

Here is a small piece of the code I am trying to get to work:

 

strConOracle = "DSN=test;Uid=test;Pwd=test;"

Set oConOracle = CreateObject("ADODB.Connection")
oConOracle.ConnectionString = strConOracle

msgbox (oConOracle.connectionstring)

oConOracle.Open

msgbox "State:" & oConOracle.state

oConOracle.Close


msgbox "State:" & oConOracle.state

Set oConOracle = Nothing

 

I've used the odbcad32.exe under C:\Windows\SysWOW64 to create my data source which connects to an Oracle DB.

I've tested an Oracle connection from both the odbcad32.exe and from sqlplus. Both connections are successful.

 

However, when I use the odbcad32.exe under C:\Windows\System32, I only see 1 driver "Sql Server". I don't see any other ODBC, OLE DB, Oracle drivers.

I've tried changing my connection string to a DNS-Less string, but I always get one of the 2 errors below:

 

Error: "

Named Pipes Provider, error: 40 - Could not open a connection to SQL Server

  

This was originally posted in the SSIS Forum, but a member of the IS team suggested it be moved here.  "Most recently I got this error (Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) so does this mean that SQL Server is still trying to use named pipes even if I only have TCP/IP enabled in SQL Server Configuration Manager?"

I'm having the same issue, and here's our scenario:

  1. Installed SQL Server 2005 Developer Edition on a machine with WinXP SP2 and enabled remote connections over TCP/IP
  2. Installed SQL Server 2005 Standard Edition on a machine with Win2003 SP1 (remote connections over TCP/IP enabled by default)
  3. Attempted to 'Copy Database' from Developer Edition TO Standard Edition using 'Detach and Attach' method and recieved the error on the Win2003 machine: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server
  4. A

web.config connection string problem within VisualStudio 2010 to point to SQL Server 2008 R2 Develop

  

Hello All, I would appreciate any help with this.

I believe my problem exists within the web.config which already had code in it to connect to SQL Server Express 2008.

I uninstalled the SQL Server Express that came with Visual Studio 2010.

I installed SQL Server 2010 R2 Developer, and I'm able to connect via Management Studio and through Visual Studio's Server Explorer's Data Connections I am connected.

I did run aspnet_regsql.exe within the 4.0 folder in order to create the database with Microsoft Service Providers.

Here is the ServerName: USER-5529234649 

Here is the name of the DataBase:  StepByStepChapter9

Here is the name of the Connection within Visual Studio's Server Explorer's Data Connections:  user-5529234649.StepByStepChapter9.dbo

Here is the code I changed in the web.config:

how to enable remote Connection sql server 2008

  

Hi

I've just installed sql server 2008 on a vista server, unfortunately I forgot to enable remote connection when I was installing it. As I need this feature really I tried to enable I but "Surface Area Configuration" of sql 2005 seems to be vanished in this new version. Despite  I searched like 2 hours, I couldn't find any useful solution,  interestingly all the results are either nonsense or related to 2005 version.

Please me what the hell should I do and I believe many people will use your answer!

Thank you in advance


Cannot connect to SQL Server 2008 RS Express, only connection to SQL Server 2008 Express succeeds?

  

Hi all,

my experience with SQL Server tends to zero. I've recently installed the new SQL Server 2008 RS Express with Advanced Services on my VISTA-machine because this version is prerequisite for installing some sample databases. There already existed a simple version of SQL Server 2008 express installed together with an older Visual Studio Express version. I thought that one would be upgraded but in fact the setup program installed the new 2008 RS version side-by-side to the older version.

The SQL Server ConfigManager shows actually both servers as running. SQL Server 2008 express named as "SQLEXPRESS" (Vers. 10.0.2531.0; path: '...\Microsoft SQL Server\MSSQL10.SQLEXPRESS\MSSQL\Binn\') and the newer SQL Server 2008 RS express as "MSSQLSERVER" (Ver. 10.50.1600.1; path: '...\Microsoft SQL Server\MSSQL10_50.MSSQLSERVER\MSSQL\Binn\'). But MS SQL Server Management Studio only lets me connect to the older SQLEXPRESS-Server, the new "MSSQLSERVER" doesn't even show in the "Connect-to-Server"-dialog.

What went wrong? I'd appreciate any help,

provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server

  

On windows 2008 using sql 2k8 standard edition. I have a couple of apps that run on the server. One works perfectly and attaches to sql with no problem. The second app that uses THE EXACT SAME CONNECTION STRING and gives me the following error,

provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server

How can one app work and the other not? What can I check for?

Thanks,


Sql Server 2008 (64bit) on Windows Server 2008 with a connection to Oracle 10g (64bit)

  

Hi,

I know there are similar questions posed but none that provided a solution to my particular problem.

I am upgrading a SSIS package from Sql Server 2005 (32bit) to Sql Server 2008 (64bit) on Windows Server 2008 R2. It worked on the Sql Server 2005 machine. This package connects to an Oracle 10g (64bit) database.

The Oracle 11g client and networking tools are installed (by the Oracle DBA). I tested my connection on the sql server 2008 machine using SqlPlus and doing a tnsping. I can also create a Windows ODBC datasource connection to the Oracle 10g database.

The package executes properly on my local computer XP (32bit) running bids 2008.

The package fails on the server in SSIS. I need to be able to schedule the package in a job so it must run in SSIS.

I have also tired to create a connection manager to the Windows ODBC oracle connection without success. It is blank and does not allow me to select or refresh to view the Windows ODBC datasources.

Any assistance would be greatly appreciated. I have seen other forums where installing the Oracle 11g ODAC and Oracle Developer Tools for Visual Studio might assist in creating the package. But I need assistance in running the package from SSIS and not BIDS.

Thanks,

Jan
