Jan 16, 2006

Hi All,

I'm developing Pocket Pc application, In that i have set of statement, which establishes connection with sql Server 2000 Database. When ever I try to open SqlConnection, I€™m getting error "Can't find PInvoke DLL 'dbnetlib.dll'.". Right now i am working in .Net Compact Framework 2.0 , But previously i worked in .Net CF 1.1 i didn€™t face problem while doing that. Can any one help me to solve this issue?

SqlCmdBuilder = New SqlCommandBuilder(SqlDataAdapter)

SqlDataAdapter.Fill(DocuMentTemplateDs.Ncm_DocumentTemplate)

Return DocuMentTemplateDs

Catch ex As Exception

Throw ex

Finally

SqlConn.Close()

End Try

End Function

' When Ever I try to call above method to retrive data from Db  , It's giving Missingmethod Exception and error message will be "Can't find PInvoke DLL 'dbnetlib.dll'."

Any idea?

Fix DBNETLIB General Network Error

Mar 12, 2007

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?

Intermittent “[DBNETLIB][ConnectionOpen (Connect()).] Error

Apr 23, 2007

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

[DBNETLIB][ConnectionWrite (send()).] General Network Error.

Sep 20, 2007



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!

[DBNETLIB] General Network Error - (I Have Included The Event Log Dump.)

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.

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,

SSPI Context / [DBNETLIB][ConnectionRead (recv()).] General Network Error

Dec 28, 2006

Hello together,


since over a week I've been looking to
find out the reason for two error messages I get from our users and
servers, unfortunately without success up to now.



I really hope you can help me.



We are using Win 2k servers with active directory and SQL Server 2000,
clients are all Win XP with SP2. Versions of access are 2002 &
2003. The errors are userspecific and occur in both versions. The
SQL-Servers are accessed with an adp-file in 2002-format.



We have one usergroup which is member of specially many groups. This
affects the size of their windows access token which becomes constantly
larger. In order to enable those users to still access their mailboxes
on our Exchange servers, the DWORD entry "MaxTokenSize" with the
decimal value "65535" was made to the newly created key "Parameters" of
their registry branch
"HKLMSYSTEMCurrentControlSetControlLsaKerberos ".



Since then those users can not access any of our SQL Servers using the
windows authentification. One of them gets the error
"[DBNETLIB][ConnectionRead(recv().] General network error. Check your
network documentation.", the others the error "Check connection:
Failed: Cannot generate SSPI context".



In case of resetting the registry entries (by deleting them), the one
user receives the same error message as the rest while it doesn't make
any difference to those (but at least they can't connect to their
mailboxes).



After having researched the web, I realised in one of the SQL-Servers
logfiles the entry "Invalid buffer received from client.." which lead
me to start to believe it could have to do something with the kerberos
encryption in the first place. Therefore I asked if changes to the
tokensize had been made. I applied the change with "EXEC sp_configure
'network packet size', 65535 RECONFIGURE" on our testsystem and "EXEC
sp_configure" confirms that the value is run.



Consequence: The entry in the SQL Server log doesn't appear any longer, but the users still receive their error messages.





Do you have any hints?



Your comments will be highly appreciated!



Regards,

caracol

Error Message: Cannot Open Database.[DBNETLIB][ConnectionOpen(Connect()).] SQL Server Does Not Exist Or Access Denied.

Mar 20, 2008

I installed SQL 2005 including backward compatibility, MSDN libraries and SP2 a new Windows 2003 server (chose mixed mode authentication). Installation was successful and I then installed an off the shelf database with Windows authentication which also installed successfully.
I created a new group in AD, added the database users into the group and gave db-owner rights to the group in SQL as advised by the installation guide. However, when I try to open the database it gives an error message saying "Cannot open database.[DBNETLIB][ConnectionOpen(Connect()).] SQL server does not exist or access denied". I also tested it adding an individual user (myself) as a user to no avail.
When I set up DSN in ODBC on my computer I can successfully test the connection but can't run the application. The connection is via TCP/IP.
Any suggestions?

[DBNETLIB][ConnectionWrite (send()).] General Network Error. Occurs When SQL Times Out On New Windows 2003 Sp2 Server

Jul 12, 2007

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.

[DBNETLIB][ConnectionRead (recv()).]General Network Error. Check Your Network Documen

Sep 30, 2004

Hello all,

We have a Windows 2003 Web Edition server serving a site through IIS. It connects to a Windows 2003 Standard Edition server running SQL 2000 SP3a.

This site receives the following error as seen in the topic:
[DBNETLIB][ConnectionRead (recv()).]General network error. Check your network documentation.

We've configured the server network utility to only allow TCP/IP connections. The connection string for the site is as follows:

<%
' FileName="Connection_ado_conn_string.htm"
' Type="ADO"
' HTTP="false"
' Catalog=""
' Schema=""
MM_connSpankMSSQL_STRING = "Provider=sqloledb;Data Source=SERVER_IP,1433;Network Library=DBMSSOCN;Initial Catalog=ourmaindb_1;User ID=ourmaindb_1;Password=hotcookies;"
%>

Any ideas or tips on solving this issue? We've noticed it is due to larger queries as smaller ones do work with no problems.

The servers are behind a BSD box running iptables, has 1433,1434 along with standard web ports wide open. Anything outbound is allowed.

Some further testing via ODBC on the IIS server improved things. No more connection pooling for the SQL Server driver allows for 1/3 of the query to run. Still 2/3s of it doesn't show up, and that general network error message appears.

Should have 330 rows if it works right.

Dbnetlib.dll ???

Dec 15, 2006

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!

DTS Package Fails: [DBNETLIB].....

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][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 ?

[help] SQL Error - I/O Error 2 (The System Cannot Find The File Specified)

May 13, 2004

Windows 2000 Server SP4 + SQL Server 2000 Enterprise Editon SP3,RAID5.

the windows event log give the following error information:

I/O error 2(The system cannot find the file specified) detected during write at offset 0x0000010c6c4000 in file 'D:Program FilesMicrosoft SQL ServerMSSQLdataGJSZBANK_Data.MDF'.

I have searched microsoft knowledge base and got this article:
http://support.microsoft.com/default.aspx?scid=kb;EN-US;828339

but don't understand some contents in the topic:

For example, if you encounter the following error message in the SQL Server Errorlog file, SQL Server encountered operating system error 2 when it uses a Windows API call to write to the tempdb primary database file:

Error: 823, Severity: 24, State: 4
I/O error 2(The system cannot find the file specified.) detected during write at offset 0x00000000284000 in file 'D:Program FilesMicrosoft SQL ServerMSSQLdata empdb.mdf'

Because SQL Server has already successfully opened the file and did not receive an “Invalid Handle” error, the error is likely being raised in a lower-level kernel software component, such as the file system or a device driver. This problem does not indicate a problem in SQL Server, and it must be investigated as an issue with the file system or a device driver that is associated with the file.

Does that mean this is not a SQL Server error?
Does that mean something wrong with my operating system? or something wrong with my hard disk?

Transactional Replication With Immediate Updation DBNETLIB Problem.

Mar 13, 2006

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 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.

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?

[DBNETLIB][ConnectionOpen (Connect()).]SQL Server Does Not Exist Or Access Denied

Apr 15, 2005

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
Catalog=myDBName;UID=myUserID;PWD=myUserPssd;persist security
info=False;" /-->


thanks,
arlena
