Please help me.
I have an asp.net 1.1 (vb.net) application which accesses data from a sql server 2000. I published this application on http://test.autenmas.co.za and the database I access is on 196.23.156.196. I am getting this error message when I run the application from this site:
System.Data.SqlClient.SqlException: SQL Server does not exist or access denied.
But it's working fine on my local, development machine. I am using the following connection string in my connections:
"Data source=196.23.56.193; Initial Catalog=Autenmas; User Id=xxxx; password=yyyy"
Is there anything wrong with my code, is there anything that must be done on the web/database server or any other configurations for that matter, what really is the problem??????
Thanks in advance.
Hi ,
I have just downloaded an evaluation version of SQL server from the microsoft website and installed it in my PC.
Now I want to create file data source.
I followed these steps:
-From the control panel, ODBC datasource admin
-click the DSN tab
-click the add button
-select the sql server driver, enter the data source file name
-enter "local" in the server text box as I installed the sql server in my standalone PC.
-click next
After that I had this error.
"Connection failed. SQL server does not exist or access denied."
But The sql server service is running.
Can anyone help me where did my configuration go wrong??
Thanks...

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?

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.
this.sqlConnect.ConnectionString = "Provider=sqloledb;Data Source=serverAddress;Initial Catalog=myDB;User Id=myLogin;Password=myPass";
I changed it from this:
this.sqlConnect.ConnectionString = "workstation id=myComputerName;packet size=4096;integrated security=SSPI;data source=myComputerName;pers" + "ist security info=False;initial catalog=blog";
the config file:
<sessionState
mode="InProc"
stateConnectionString="tcpip=mssql.mySqlSource.com:42424"
sqlConnectionString="data source=mssql.mySqlSource.com;Trusted_Connection=yes"
cookieless="false"
timeout="20"
/>
Question- that port number, does it need to be changed?
I know that the server is running both 1.1 and 2.0 framework. Not sure if that could be an issue or not.
In Advance I want to say thanks for any support I receive.
The Fatthippo.
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?
Thanks
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?
View 14 Replies View RelatedI'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 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.
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
Thanks for any help you can give

Hi,
I have problem in connecting SQL Server 2000.
The Operating System I am Using is MS 2000 Proffesional, I have Installed SQL Server 2000 Client.
I have Installed the SQL Server(Standard Edition) on MS Server 2003 and also the Sql Server 2000. This is my Domain Server.
Through ASP.NET when i am trying to connect through the Connection String it says "SQL Server does not exist or access denied"
I have no problem in connecting through SQL Server Manager & Query Analyzer.
Could Any one tell me the right way to connect to Remote Server.
Thanking You,
Regards,
M.Upendra Nath
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.
Thanks
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.

Just looking for nay help. Thanks in advance.
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...

thank you for th ehelp and for the time
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.
But it's not what you think...
Here's the twist: the connection from the web server to the SQL server works like 99% of the time. Meaning I have the credentials, connection string etc. configured correctly, right? However, this exception rears its ugly head randomly throughout the day. Below are my documented observations:
-The web server is able to communicate with other SQL servers always (I think). However, one in particular fails inconsistently when using references to the IP OR server name.
-The problem is occurring throughout the entire day, but not in correlation with any scheduled activity or pattern that we’ve been able to observe.
-Computers other than the web server are able to connect to the SQL server (via remote desktop or SQL Enterprise) and see the SQL service as running. I’ve even been able to run queries from my local machine while the web server claims that it doesn't even exist.
-Stopping the IIS and SQL services and or restarting the machine does not necessarily fix the problem.
A few other comments:
We are currently set to run Named Pipes, TCP/IP in that order. Also, our network consultant(which is supposed to be good) has "verified" that the machine is networked correctly. Meaning, it is on a static IP and whatever else they would normally check. My connection string is said by Microsoft to be completely supported -- namely "server=serverip;database=dbname;uid=sa;pwd=nottelling". Connecting with this string using the .net SqlClient does not require an ODBC system DSN to be set up does it?
Does anyone have any suggestions? I've tried EVERYTHING to get this to stop! I'm thinking of ripping out and replacing the NIC card in the suspected machines just for giggles. Below is my error just in case you've never seen it. Looks pretty normal to me...
SQL Server does not exist or access denied.
