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
Hi have created an application in asp.net to connect to a sql database. The reason why I am sooooo very confused is because the connection to the database works if i keep the project on my local machine and connect to the database on the server, but as soon as I upload the project to the server, I get the following error when I try to connect to the database: [DBNETLIB][ConnectionOpen (Connect()).]SQL Server does not exist or access deniedCan anyone tell me why this is happenning? - PLEASE - Any help will be appreciatedThanks, Danielle
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
Lets get this out of the way first - I KNOW NOTHING ABOUT SQL SERVER, MSDE or MDAC
Sorry I don't mean to shout but I really don't know anything at all so please make your answers as simple as possible.
I have an application (Webmarshall) that has a SQL database from which certain reports are run. Whenever I try to run the reports it asks me for database details.
According to the application it is using LANCELOTWEBMARSHALLWebmarshall as the database
As this is all happening on one server, I presume it is local and not remote.
When I am presented with the dialogue box for the reporting module it asks for a server and a database, I have tried the following :
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?
Okay Ive managed to confuse myself pretty good.I have an aspx page that attempts to connect to an SQLEXPRESS instance and add data to a table.Code as follows:beginning of page<%@ page aspcompat=true enablesessionstate=false language=javascript %><!--#include file="adojavas.inc"--><%@ Import Namespace="System.Data.OleDb" %>I have a toolfunction that when called upon runs this:if (xco >= -180 && xco <= 180 && yco >= -90 && yco <= 90) { status = "Can't connect to database."; // create connection to database var connection; connection = Server.CreateObject("ADODB.Connection"); connection.Open("Provider=SQLOLEDB.1;Integrated Security=SSPI;Persist Security Info=False;Initial Catalog=OutdoorsExp;Data Source=\.pipeMSSQL$SQLEXPRESSsqlquery;"); status = "Can't access table."; // create recordset var recordset; recordset = Server.CreateObject("ADODB.Recordset"); recordset.Open("dbo.FishType", connection, adOpenDynamic); status = "Can't append new record, record set does not support AddNew."; // append record for clicked location if (recordset.Supports(0x01000400)) { status = "Can't append new record."; recordset.AddNew(); recordset.Fields("LongitudeI").Value = xco; recordset.Fields("LatitudeI").Value = yco; recordset.Update(); } recordset.Close(); // release the file connection.Close(); status = "Can't propagate changes to drawing."; // refresh drawing var document = mapserver.Document; var componentIndex = document.ComponentSet.ItemByName("FishTable Data Points Drawing"); if (componentIndex >= 0) { document.ComponentSet.Item(componentIndex).Refresh(); } status = xco.toString() + ", " + yco.toString(); }Unfortunately this gives me an error instead of transferring the value xco,yco to the SQL Tables LatitudeI/LongitudeI column.Ive tried many different connections strings, and have played myself into a state of confusion now :(.I get this error:[DBNETLIB][ConnectionOpen (Connect()).]SQL Server does not exist or access denied.[COMException (0x80004005): [DBNETLIB][ConnectionOpen (Connect()).]SQL Server does not exist or access denied.]Ive tried named pipes and using IP to connect, and Im not 100% sure how to use SQL Server via "System.Data / System.Data.SqlClient".Any insights would be greatly welcomed!
I am trying to link SQL SE 2000 (Local server at head office) to MSDE 2000 (remote server). After creating the server group in local server, I try to register SQL server Computers (MSDE 2000) to place in it.
But I received this error message.
"SQL server registration failed because of the connect failure displayed below. Do you wish to Register anyway
SQL Server does not exist or access denied connectionOpen(Connect()).'"
I checked the setup for client and server utilities.
Client Utility is TCP/IP Server Utility is Named pipe
Please, help me. I don't know what went wrong here.
The server that needs to be moved: SERVER A. The databases which need to be moved (present in SERVER A): DB-A, DB-B. The SERVER A machine is in X domain
The target machines: Could be any of SERVER T1 This machine is in Y domain.
While we are trying to create a new server instance of the Server A in SERVER T1, we are getting an error message as shown below:
Reason: SQL server does not exist or access denied. (ConnectionOpen (Connect())
The server that needs to be moved SERVER A could not be mapped to SERVERT1.
Problem: The tables concerned present in the SERVER A and the production server are same. These could be extracted to SERVERT1 using the SQL Enterprise Manager utility. Views and Stored Procedures concerned are only present in SERVER A. Problem lies in copying them. Manually doing so could pose great risks. What is the plausible work around for this?
when I was sending 50 simultaneous connections to the web services, I got these 2 errors: - "1[Microsoft][ODBC SQL Server Driver][DBNETLIB]SQL Server does not exist or access denied. "
- "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: TCP Provider, error: 0 - A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.)"
Everything worked fine if I ran 10 simultaneous connections. I am using Microsoft ACT to load test the web service. The database is SQL Server 2000. Any idea about why this is happening?
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
I have been having problems after I make a connection from my application to a SQL Server 2005 database that is located on a different machine. After a few minutes it gives me the SQL Server Does Not exist or Access denied message. I am able to connect to it through SQL Server management studio. I am doing some data intensive operations by copying data from different tables on the remote server onto text files on my local machine. Any suggestions?
Hi! I understand that this topic is one of the most discussed topics ever. However i could not find the relevant information after going through (almost) all the posts so far. Hence this post. I am getting the 'SQL Server does not exist or access denied' error when I am trying to access SQL Server from a WINDOWS SERVICE. SQL Server and the Windows service are running on two different machines. (When they are on the same machine, it works). All the solutions I found so far are related to web apps. What should I do in the case of a windows service? My connection string uses SQL server authentication. (I tried with windows authentication. Its not working either.). Under what login does windows services run and how can I add it to valid SQL server logins?
When i am trying to start our hospital software based on SQL server 2000, it shows Following Error.Search Condition is not valid, (DBNETLIB) Connection Open (connect()).  SQL server does not exist or excess denied. Due to Fetch data.I run our software in Windows 8.1, while it smothly runs in previous version of Windows XP and 7.
I have recently deployed a web app that I have been developing onto the production server (Windows 2003 SP1 + an SQL Server 2000 SP4 cluster). The web app uses both Enterprise library and another Dotnet based database abstraction layer to query SQL Server. However, on deployment, when requesting data through both abstraction layers, I receive the generic SQL Server does not exist or access denied. However, I have validated the configuration of Enterprise library by creating a simple diagnostics console app that uses the exact enterprise library configuration file and this can connect without a problem. It seems like only web applications are affected though this is fairly standard web app using ASPNET, user , no impersonation etc. Therefore I suspect something similar to permissions on dlls or similar. I have looked around at Windows, WindowsSystem 32, the Dotnet framework but can anyone suggest any other areas to look at?
Does the error below look familiar to anybody? I cannot seem to get past it! My connection code is <sessionState mode="SQLServer" stateConnectionString="tcpip=BRAHMA" sqlConnectionString="data source=epscor;user id=epscorser;password=epsc0r" cookieless="false" timeout="60"/> Help in solving this appreciated! -Steve SQL Server does not exist or access denied.

Hello everyone, I’m hoping that someone could help explain why I get this error “SQL Server does not exist or access denied.� . I’ve migrated to the web server from my local machine and these are the steps I took: 1.Copied folder to web server. 2. Changed connection string to connect to DB 3. modified web.config
Being the first time I’ve done this I’m also posting the connection string and config file code.
We have sql server with the name production1 (IPID:100.102.33.33) ,from asp.net iam able to connect properly ,yesterday we changed the ip Id of this system(production1) from that time if iam trying to connect from asp.net code it is giving error sqlserver does not exists access denied.
Iam able to connect in query analyzer by using same userid,password. Iam able to connect in vb.net with same connection string which iam using in asp.net Iam unable to connect in asp.net error sqlserver does not exists access denied. Please help me is there any problem with asp user or what?
I think its my server because I cant get it to link up to an Access data base either, heres the error I get.[DBNETLIB]ConnectionOpen (Connect()),]SQL Server does not exist or access denied.Im pretty sure that all the fields that I entered are correct though.What could be the problem? Someone mentioned that the network protocol configuration maybe isnt setup right. Could this be the problem? If so how would I properly configure this?
I've got a SQL2000 named instance on a box that also has SQL 2005. Both database versions have run side by side for some time and I don't USUALLY have a problem (famous last words!). I'm currently getting the error in the subject line trying to connect to it as "MACHINENAMESQL2000", SQL2000 being the named instances, from another machine. It works fine from the local machine, naturally. I have verified my creditials, i.e. both Windows Authentication and a SQL login work fine from the local machine. The machines are physically on the same subnet (they're actually side by side) and both can talk to each other just fine, i.e. they ping, and can map drives, etc. Any tips/ideas on how to trouble shoot this? Is there a new security switch that needs to be set to make the db visible to other machines?? -Confused
I' ve wrote the following simple asp.net code to test the connection to my local SQL server: SqlConnection connection = new SqlConnection ("server=localhost;uid=sa;pwd=;database=pubs"); try { connection.Open(); } catch(SqlException ex){ Label1.Text= ex.Message;} finally{ connection.Close();}
But each time I got the following errors: SQL Server does not exist or access denied.
Can anyone help me find out when my problem lies?
BTW, the SQL service in Control Panel has been started, and my local SQL server uses windows and SQL authentication. When I use osql -E -S MyMachineName(This MyMachineName is some kind SQL Server Registration in SQL Server Group of SQL Server Enterprise Manage), everything seems to be fine, but it does not work when I use osql -E -S localhost.
Trying to get Quickstart tuts up and running. I get this error whenever i try to run any examples.

I installed the MSDE (i think) and i see the service MSSQL server running. I don't see the icon in the system try that shows SQL server is running. I don't even know how to check to see if the MSDE is installed. There is nothing in my Start>>Program Files MSDE related. What am i doing wrong? Thanks!
Trying to get the Quickstarts up and running. When i go to one of the server side data access tutorials i get the error: SQ: server does not exist or access denied. I am using SQL server 2000. Any reason i would be seeing this?
Also, to see the quickstarts i have to browse to httP://localhost/quickstart/.....if i try to go to http://machinename/quickstart/ i get access denied. Any reason for that?
I'm getting the following error when I run my web app: SQL Server does not exist or access denied. I created a role in my db and added a user to that role. I gave the user the appropriate permissions. I also gave the user the appropriate permissions to my tables.
I get the following error when I try to access SQL Server:
