[DBNETLIB][ConnectionWrite (send()).] Errors
May 23, 2007
We have a Dell 2950 running Windows 2003 connecting to SQL2005 Database.
Users accessing their SQL application are getting this error message after leaving the application open for a period when they are not accessing the system. We have run the application on two different servers and cannot re-create the errors, which might suggest a hardware problem with our server, but as yet we haven't identified the problem.
Does anyone have any ideas ?

Hi ALL
I am facing a strange problem using ADO to connect Sql Server that I can not resolve it.
My program connected to SqlServer when it started, the state of the connectionPtr was adoStateOpen.Then I disable the network card and enable it immeditately, the errors happened when I executed the sql query probably because of connectionPtr was invalid,but the state of connectionPtr was always adoStateOpen.
1)Msg: Unspecified error Source: Microsoft OLE DB Provider for ODBC Drivers Description: [Microsoft][ODBC SQL Server Driver][DBNETLIB]ConnectionWrite (send()).
2)Msg: Unspecified error Source: Microsoft OLE DB Provider for ODBC Drivers Description: [Microsoft][ODBC SQL Server Driver]Communication link failure.
Should I reconnect to SqlServer?How can I catch this error when the connection is valid except other errors?
Sorry,my english is poor and thanks for your response.
Thanks a lot.
Env:
1)OS : Windows 2000 Server
2)SqlServer:Sql Server 2000

Hi,
in our environment
- Windows XP
- SQL Server Express 2005
- Internet connection via TCP/IP protocol
The described network error occurs, when we unplug the network cable:
[DBNETLIB][ConnectionWrite (send()).] General network error.
The affected database resides on the locally installed SQLExpress, it doesn't use any network connections. The error doesn't occur immediately, in most cases there are up to 30 seconds where data can be (correctly!) written to the recordset, but after that timeout the connetion is broken.
We already tried out the described workarounds:
- disable named pipes protocol
- set SynAttackProtect=0 in HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesTcpipParameters
The error doesn't occur with MSDE (SQL 2000) or under Vista.
Thanks for help!

We just replaced an older Windows 2000 sp4 server with a new Window 2003 Standard Edition sp2 server to run our batch processing. We noticed that when the SQL command times out we now get the following error in the ADO command object error collection.
[DBNETLIB][ConnectionWrite (send()).] General network error. Check you network documentation.
Native Error: 11
SQL State: HY018
msado15.dll version 2.82.3959 is on this server.
On other servers running Windows 2003 Enterprise Edition sp1 the error on the ADO command object is normal with.
Timeout expired
Native Error: 0
SQL State: HYT00
msado15.dll version 2.82.1830 is on this server.
The SQL server they are talking to is on the other side of a firewall. It is SQL 2005 sp2 running on Windows 2000 sp4.
I have also tested this on a Windows 2003 sp2 server that doesn't have to cross a firewall and get the correct Timeout error. It also has the same version of msado15.dll as problem server.
The application is a collection of VB6 Components that are running in COM+ applications. I have isolated the test application to our one SQL interface component and have build a test vbs that can reproduce this on demand. The VB6 Components were not modified in any way for this change and have been working fine for many years prior to this.
All other aspects of our batch processing works as expected. Transactions are working fine. As long as the SQL doesn't timeout everything is normal. DTCPing was used to ensure both servers have correct ports open to allow DTC traffic. Checked the SynAttackProtect setting on SQL and this is not an issue since other clients have no problems.
One point I would like to add is that this new server was initially setup with a temporary server name and then was changed to use the name of the original server on move day. Don't know if this has any impact or not.

Since we change the web server to window 2003, we occasionally receive the message
[Microsoft][ODBC SQL Server Driver][TCP/IP Sockets]ConnectionWrite (send())
We use ASP and ODBC to access sql 2005. I have specified to use TCP/IP and port 1433 in ODBC.
Any idea to solve it?
Thank you in advance.

Ok, I'm incredibly new to all of this so please bear with me. I took the Integration Services tutorial, and that's pretty much all that I have done.
I'm creating my first package and I want to be able to email myself when certain non-fatal conditions occur. I still want the entire row to flow into my table.
My understanding is that this type of checking should be done in the "Data Flow" tab not the "Control Flow" tab. However, I can't see a toolbox item in "Data Flow" to create a SQL script like this. I can see that the "Lookup" toolbox item will allow me to write a SQL script but how do I get it to send out the email? Or should I really be doing this type of checking in "Control Flow" where there is an "Send email task" item?
Any help is greatly appreciated! Thanks!

Hey there all,
i am having a weird problem with the send mail task in SSIS. I have tried to different things, and i end up with two different errors:
Firstly, i have setup a data dump to excel, and the send mail taks emails this to specific email addresses.
In the Send mail task i have validated to SMTP server, and its correct.
I have manually entered all the information in the Send mail task, and i am sending to multiple email addresses. These are all seperated by a semi colan. I run the task and it fails on the send mail task with the follwoing error:
Error: 0xC002F304 at Send Mail Task, Send Mail Task: An error occurred with the following error message: "Unable to send to all recipients.".
Task failed: Send Mail Task
I have validated all the email address and they are correct. I did some searching and someone suggested to replace the semi colan with a comma. I do this and i get the follwoing error"
Error: 0xC002F304 at Send Mail Task, Send Mail Task: An error occurred with the following error message: "Mailbox unavailable. The server response was: 5.7.1 Unable to relay for rpwallis@bigpond.com.au".
I have checked that the IP for the SQL server is on the list of allowed relays on our exchange server. Does it make a difference if i am running this from Visual studio on my laptop?? by this, does it pick up the ip of my laptop when i test this or does it use the ip address of the server?? This would explain the relay message error if so..
Could someone please explain if i should use comma's or semi colans to seperate email addresses? and also lead me in the right direction in relatio to my problems..
Many thanks in advance

I'm programmatically loading a package that was created with VS 2005. The last task in the package is a Send Mail Task. It has two properties, FileAttachments and ToLine, which are set to expressions whose values come directly from package variables. The package runs in debug and non-debug (under VS) correctly.

Hi,
Can anyone shed any light on a connectivity issue I am seeing 'in the field'?
I am using a SQL2005 Express SP2 'default' instance database running on a WEPoS (a prepackaged XPe SP2 variant for Point Of Service) platform.
The application connects to SQL via an ADO trusted connection / DSN pointing to '(local)'.
SQL2005 is configured to use shared memory for local connections and named pipes for remote connections.
This all runs fine (sometimes for days on end) ... Then out of the blue I get the following error:
[Microsoft][ODBC Sql Server Driver][Shared Memory]ConnectionWrite (send()).
SqlState 01000 Err: 0x2746
In the latest example this was on an 'INSERT INTO' statement with 7 parameters (~100 bytes the lot!)
Resetting the connection (.close->.open) in the connection error handler reconnects fine and catches the error in the majority of cases, but unfortunately this is not possible from some of the older (closed source) code we use.
Has anyone else had similar experiences?
Better still does anyone have a workaround that does not involve changing application code?
I also made the observation (and this may be a red herring as no LAN comms is required in this case) that the external PC LAN connection was intermittent around the time of the error - although the timestamps from the logs were off by 10/15 mins.
A/Virus McAffee v4.5.1 SP1 is also installed on the PC.

What is the meaning of "Can't find PInvoke DLL, dbnetlib.dll"??
I got this error message when trying to access the server, I'm developing SQL Mobile app.
How to solve this problem??
thx
I have two apps, with the same code on both app :
Dim ConnStrToServer As String = "Data Source=myIP,1433;Initial Catalog=mydatabase;User ID=sa;Password=;"
Dim connection As New SqlConnection(ConnStrToServer)
connection.Close()
MsgBox("This will take a minute")
Try
connection.Open() -->> ERROR!!
Dim queryString As String = _
"Update mytable set flag='PESAN'" & _
", username='" & tbIdNumber.Text.Trim & "'" & _
", tglpenyerahan='" & Now & "'" & _
" Where KodeProyek='" & kodeProyek.Trim & "' And NoKavling='" & NoKavling.Trim & "'"
Dim adapter As SqlDataAdapter = New SqlDataAdapter( _
queryString, connection)
Dim mstmap As New DataSet
adapter.Fill(mstmap, "mytable")
connection.Close()
Catch ex As Exception
MsgBox(ex.Message)
End Try
the different is the first app is a SQL Mobile app, now when I try to open a connection from the first app is always shows that error with the above code (eventhough my replication not error), but when I try to execute (success open connection) the query with the second app (not SQL Mobile app) works!

I have a job that emails out shipment notifications at the end of the day to our customers. The problem I have is I don't understand why the same email is sending out twice within a minute of each other when the job is only scheduled to run once. If I take the code out of the step and run it in management studio it only emails once. I attached the code for one customer for reference. We are running SQL 2008 on a VM sending to an exchange 2010 server.

SQL Server is running on my PC. The server name is 'ASPEN'. When I create a DTS package to export a local database to our live site, I must use 'LOCAL' for the server name, not 'ASPEN'. Everything runs fine the first time, but later, when I try to execute, or even view, the local package I saved, I get the following error:
[DBNETLIB][ConnectionOpen(Connect()).]SQL Server does not exist or access denied.
Can anyone explain this?

Any idea?

I have a friend at another company that is getting this error:
03/07/2007 16:03:49 Version 21.00.69 - UID - xxx - Error -2147467259 - [DBNETLIB][ConnectionWrite (send()).]General network error. Check your network documentation.
I have checked around and found two potential fixes for this problem. The first one describes this as a problem specific to the Named Pipes protocol. The fix is listed as available from this site:
http://support.microsoft.com/default.aspx?scid=kb;en-us;827452
The second fix is listed as making an additional entry to the registry like this:
The problem arises on a busy SQL system and some requests will randomly seem
to be dropped with a General Network Error.
To fix:
HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServic esTcpipParameters
Add a new DWORD key SynAttackProtect with value of 0. Restart server.
Can someone tell me if either or both of these approaches is correct?

Hi,
I have a classic ASP app that loops through a record set and calls another query based on each record returned. Something like:
sSql = User Query
rsUser = conn.execute(sSql)
do while not rsUser.eof
sSql = Select [Type] From [User Types Display] Where UserId = rsUser(€œUserid€?)
rsType = conn.execute(sSql)
€˜ Put information into HTML table
rsType.Close
rsUser.MoveNext
loop
In general, at around 3575-4000 loops, the system kicks back :
Microsoft OLE DB Provider for SQL Server error '80004005'
[DBNETLIB][ConnectionOpen (Connect()).]SQL Server does not exist or access denied.
UserList.asp Line 300
I get no error message in the SQL Server Logs (according to the server, nothing happened), just this message on my ASP page. This happens about 90% of the time. 5% it runs completely, the other 5% bombs after 1-100 loops.
This only started happening when we took our app from a local Server 2000/SQL 2000 setup to separate Server 2003/SQL 2005 setup.
In SQL Profiler I see the loops hitting with only two reads per batch (TCP/IP). This seems very low compared to named pipes (when in a local server configuration) reads of 15-30 reads per batch.
I know it is not a hardware issue; this behavior is observed in both our test and production environments. All of our other ASP page queries work fine, just the 2 or 3 of hundreds that loop like above. cause the error.
Client Details (as best I could):
Connection String (in .inc file): conn.Open "Provider=SQLOLEDB;Network=DBMSSOCN;Data Source=10.0.1.100;Initial Catalog=€™TestDB';User ID='XXXX';Password='XXXX'"
The Client is Remote to the SQL machine and connects through TCP/IP only.
I force no encryption on the back and forth between the servers.
Server Details:
SQL Server 2005 Standard with SP1
Only Named Pipes and TCP/IP are enabled
I think this is all the info relative to my issue.
Thank you so much for any help,Smith

Hi,
I am trying to set up Transactional replication with immediate
updation.
The configuration is as follows:
1. Publisher is SQL server 2000 Enterprise Edition, and Distributor is
on the same server.
2. Publisher SQL server Standard Edition is installed on Windows 2003 with sp1.
3. Subscriber is an SQLServer 2000 Evaluation version on Windows
Professional 2000 with sp2.
When I set up the Publisher with transactional replication with
immediate updation only, the set up was successful.
I subscribed 2 instances of SQL server from Windows 2000 professional
on the local LAN in the same domain. The set up went fine.
When I update from the publisher end the updation is successfully
replicating to all the subscribers. But when I try to insert any
records in any one of the subscribers, I am getting the following
error:
[Microsoft] [ODBC SQL Server Driver ][SQL Server
][DBNETLIB][ConnectionOpen(Connect()).] SQL Server does not exists or
access denied.
I am beginner to this replication technology, but I have to set up in
my organisation. Please anybody help me in figuring out the actual
problem and resolving it.
Thanks in advance.

I recently updated the datatype of a sproc parameter from bit to tinyint. When I executed the sproc with the updated parameters the sproc appeared to succeed and returned "1 row(s) affected" in the console. However, the update triggered by the sproc did not actually work.
The table column was a bit which only allows 0 or 1 and the sproc was passing a value of 2 so the table was rejecting this value. However, the sproc did not return an error and appeared to return success. So is there a way to configure the database or sproc to return an error message when this type of error occurs?

hello,
I hope someone can help me with the problem I am having, I get the following error:
[DBNETLIB][ConnectionOpen (Connect()).]SQL Server does not exist or access denied
I am trying to connect to my SQL
Server 2000 db via asp.net. The aspx file uses a DataGrid, the aspx.vb
code behind file gets the connection string from the web.config file. I
tested my connection via ODBC, or SQL Query Analyzer just fine so I
know the userid/password is correct.
this is the snipplet code from the aspx.vb code-behind file:
Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) _
Handles MyBase.Load
Dim dbConn As OleDbConnection
Dim dCmd As OleDbCommand
Dim dReader As OleDbDataReader
Dim strConnection As String
Dim strSQL As String
If (Not Page.IsPostBack) Then
Try
'get the connection string from web.config and open a connection
'to the database
strConnection = ConfigurationSettings.AppSettings("dbConnectionString")
dbConn = New OleDb.OleDbConnection(strConnection)
dbConn.Open()
'build the query string and get the data from the database
strSQL = "SELECT Title, ISBN, Publisher " & _
"FROM Book " & _
"ORDER BY Title"
dCmd = New OleDbCommand(strSQL, dbConn)
dReader = dCmd.ExecuteReader()
'set the source of the data for the datagrid control and bind it
dgQuick.DataSource = dReader
dgQuick.DataBind()
Finally
'cleanup
If (Not IsNothing(dReader)) Then
dReader.Close()
End If
If (Not IsNothing(dbConn)) Then
dbConn.Close()
End If
End Try
End If
End Sub 'Page_Load
End Class
this is the connection string inside the web.config file:
<!--add key="dbConnectionString"
value="Provider=SQLOLEDB;Data Source=localhost;Initial
Catalog=myDBName;UID=myUserID;PWD=myUserPssd" /-->
<!--add
key="sqlConnectionString" value="Data Source=localhost;Initial

ok im a CS student, installed visual studio .net, and im trying to connect to a ms sql database (Northwind), but I keep getting a error that "[DBNETLIB][ConnectionOpen(Connect()).] SQL Server does not exist or access denied" in visual studio whenever I try creating a new database connection. How do I know if SQL server is installed on my system? cuz in my systray I see SQL server service manager, is that the same thing as SQL server? or do I need to download the full version or something? also could it be that a certain port on my system is not open that SQL server requires to be open?
Thanks
Ron

Hi all.
I'm running a large data transaction and get the next error :
[DBNETLIB][ConnectionOpen (Connect()).]SQL Server does not exist or access denied.
In this case, I process over many, many records, and then it finally indicated the server doesn't exist. This only occurs sometime.
I have SQLServer 2000 on Windows 2003 Server
Some idea how to solve this.
Thanks advanced
Wil.

I have a MS MSDE 2000 database that is serving 3 database clients. Intermittently, randomly, and more important daily, my clients receive a "SQL Database Connection Error", and they are kicked out of the database. This appears to be correlated when they are writing/retrieving a record.
MS MSDE then writes the following error in it's event log.
--------------------------------
Source: SORules.Gateway.LogErrors
Process ID: 2328
Database connection lost
Error #-2147467259
[DBNETLIB][ConnectionWrite (send()).]General network error. Check your network documentation.

Any help, suggestions, or thoughts would be greatly appreciated. This is for a small business line of business application that is critical for everyday business operations. These problems have resulted in lost work, short tempers, and a just frank frustration.
I am just getting started with MS SQL technologies and really need some quality help.
Thank you for your time, and have a great day.
Cheers,
Mark
