SQL Server Does Not Exist Or Access Denied Message
May 5, 2004
Hi,
Over the last couple of years on my development machine, I occasionaly received the error:-
'SQL Server does not exist or access denied.'
when testing my web app. All I had to do was stop SQL server and restart it and the problem would go away.
Unfortunately i'm now getting the error everytime, and no amount of stopping/restarting SQL Server makes any difference. I can make remote connections ok, just can't make any local ones.
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?
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.
System.Data.SqlClient.SqlException: SQL Server does not exist or access denied
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:
SQL Server does not exist or access denied. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.Data.SqlClient.SqlException: SQL Server does not exist or access denied
and I also get the following Warning in the System Log
The server was unable to logon the Windows NT account 'ECOM411-BOYSSWGASPNET' due to the following error: Logon failure: unknown user name or bad password. The data is the error code.
I have settup the account 'ECOM411-BOYSSWGASPNET' on the SQL Server and have given it access to the my DB... Could some one tell me what could be wrong??
I have 2 servers. one is the web server and the other is the sql server. web server(iis) is on windows 2000 and sql server is hosted on windows 2003
i can't connect to the sQL Server hosted on my Windows 2003 machine from an asp.net application. This is the error message i am getting. "SQL Server does not exist or access denied."
The sql server is set for both windows and sql server authentication. I have no problem connecting to it from the Web server using Enterprise Manager or Query Analyser. The password is correct and username sa has full access.
This is the code i am using. the code is fine. i have used it 100s of time. the code below will work if i change the data source to "localhost" to connect to the sql server that is hosted on the same machine.
Dim strCon As String strCon = "data source=Data1;initial catalog=MyFriendsNet;password=blah;persist security info=True;user id=sa;workstation id=Web1;packet size=4096" Dim MyConnection As SqlConnection = New SqlConnection(strCon) Dim MyCommand As SqlCommand = New SqlCommand("Select * FROM Users", MyConnection)
MyConnection.Open()
Dim MyDr As SqlDataReader = MyCommand.ExecuteReader
While MyDr.Read() Response.Write(MyDr("FirstName"))
End While
MyDr.Close() MyConnection.Close()
This probably has to do with some kind of authentication issue. anyone have any ideas.

As shown by the post topic, I am trying to connect to a remote sql server through enterprise manager, and have been getting "SQL Server does not exist or access denied".
I have disabled Named Pipes, made sure it's listening on port 1433, triple-checked the user account, etc. Still nothing. The server is behind an ISA server, that has packet filtering turned on for 1433 also, yet I can't help but think the ISA server is to blame....
I am baffled after reading multiple tech docs and forum posts.
ANY HELP would be GREATLY APPRECIATED. (I'm pulling my hair out).
ASP.NET page on dev server and live server both access data on live server.
A couple of days ago I started getting "SQL Server does not exist or access denied" error when running the pages on the Dev server.
Looking at the live server logs I see:
Logon Failure: Reason:Unknown user name or bad password User Name:ASPNET Domain:FS-DEVWEB-2000 Logon Type:3 Logon Process:NtLmSsp Authentication Package:NTLM Workstation Name:FS-DEVWEB-2000
What changed? Why can't the ASP.NET on the Dev server get SQL data from the Live Server. All the connection strings are correct. I can get the same SQL connection and queries running in Enterprise Manager and Classic ASP from the Dev server to the Live Server.
Any ideas how to fix this. I'm sure I just have to some how tell the live server to trust the Dev server.

Hello Everyone and thanks for your help in advance. I am having an awful time debugging a SQL Server Connection issue. I have a new installation of a Windows 2003 Server and SQL Server 2000. I have an ASP.Net application that is currently functioning on a Windows 2000 Server. I have donwloaded all of the latest service packs. I have verified that the SQL Server uses both SQL Server and Windows authentication. I have set the connection string in the web.cinfig to:
But nothing seems to get me connected. I have read numerour KB articles, but can't get resolution. I desperately need help. Any insight would be enormously appreciated. Thanks.

alright here is the problem though Using this connection UNALTERED i can go into this data adapter run this query through query analizer and it works great I can make it fill the dataset in the IDE but when i run the page it gives this error when creating a connection to this computer i save the password so it should not need the password when i create this connection I select the server i use my login I select the database click "Test Connection" and it works correctly and as i said earlier i can use this connection in the IDE without any problems what-so-ever is there anything you can tell from this
in sql server under properties of the server -> under the security tab -> under authentication i moved the option to "sql server and windows" from "windows only" so that i could login from a remote server is there something else i should change also?
The program works correctly on my development computer running sql server 2000 on windows 2000 pro
the other sql server that is giving me the problems is located on a windows 2003 server with sql server 2000
I am getting this message error when executing my first web application. I am using MSDE and executing on the same computer. Here is the code i am using. The name of the local computer is winxp.

By any chance it it possible to find whether SQL Server is exist or not OR whether it is working or not from asp.net code? I can redirect him if any runtime errors comes in my website.But I want more specifically tell the user that It's becuase of the SQL Server.
Same thing I want to do for SMTP (mail server) also.
Ever since I demoted my Active Directory domain controller, I haventn been able to connect to this server from a remote server on the same network. I havent been able to connect at all...not even from behind the firewall.
I'm thinking it has something to do with the logins getting jacked up somehow...after the demotion. I can share a folder on the demoted domain controller, and access it. I can also connect via to its IIS from the remote machines IIS. I'm only having trouble with this right here.
I also installed SQL Server client tools on the remote machine, but I doubt that has anything to do with it.

I'm just learning ASP.NET and have been using WebMatrix to create a few simple pages which access an SQL Server database on another server. This has been working fine.
Now I'm trying to learn Visual Studio and have just done the "Creating a Web Application Project" walk-through. I'm accessing the same remote database and everything goes smoothly until I try to run the project.
No problems with Build Solution, I can 'Retrieve Data' from a table in Server Explorer, and the 'Test Connection' test worked properly. But, when I 'Start Without Debugging' (or a regular 'Start') I get the error:
"Exception Details: System.Data.SqlClient.SqlException: SQL Server does not exist or access denied"
Any help would be greatly appreciated. Thanks...
(I've gone through the walk-through 3 times using different databases (including Pubs) and always get the same results)
I get the following message running an ASP.NET application on my development machine
SQL Server does not exist or access denied
It was working fine until a coupe of weeks ago, and our live website has no problem. What's weird is that tt works for about 10 mins and then it generates that error again, which means that the connection string is right..
We are using the mixed mode of Windows and SQL authentication and the protocol we use is TCP/IP and Named Pipes. I even tried rebooting the sql server and my development machine. It didn't resolve it.
This is really bothering me. Does anyone have any ideas?
Hi, I have a ASP.NET project running on a Windows XP Professional machine and a MSSQL Server 2000 running on a windows 2003 machine.This project connects to the MSSQL database for its dynamic content. When running the project locally (project and mssql server on the same machine) it runs fine.But when running it in the configuration above (project on xp professional, mssql server on windows 2003) I get the error SQL Server does not exist or access denied. I've searched google for quiet some time now and tried every solution I could find but I keep getting this error.I've also tried to run it on 2 XP Professional machines (one with the project the other with the mssql server) but still the same problem.Also tried connecting to the ip in stead of the dns, but no luck.Tried to change the port as well, but same problem persists. When I do netstat -a on the windows 2003 machine I see the status CLOSE_WAIT for the port 1433 (same when changing to another port). Does this mean the port is being blocked? If so how can I open this port? There are no firewalls running on the network.
