I am trying to remotely connect to a Database and every time I try I get the error:
A connection attempt failed because the party did not properly respond
First thing, Please recheck the connection string: server, database and user used to connect it.
Secondly, make sure user you are using for connection is having sufficient permission over database.

I am using Connection string in my web.config. I have given user id, password, data source etc in the connection string. When i tried to connect to the SQL server using "Connection.Open()" I am getting an exception stating The user is not authorized. The user name that is mentioned is my windows user name(yes my windows user name and not the one mentioned in connection string). I am not sure why and how this is happening. I tried several times and the same thing is happening.
If you believe that VB.NET is part of the problem, try using the same connection parameters from the same client, but with different client software. For example try connecting from Access or SQL Server Management Studio or Excel. This will help you narrow down whether your problem is with the security configuration versus the code or client software. Often times if you try to connect from a remote workstation you can end up with a failure against a server that has not been configured to allow remote connections.
Im currently making a wpf Windows Application, and it withdraws data from a database, so it is needed that I setup a connection to my remote servers SQL Server Database. Now i am getting a couple errors. When I first of all try to connect to my remote servers Sql Server using management studio, just to test if I could actually make a connection, I get the following error.
A connection was successfully established with the server, but then an error occured during the login process. (provider: Named Pipes Provider, error: 0 - No process is on the other end of the pipe.)
(Microsoft SQL Server, Error: 233)
And ovcourse, I did try my best to do my research, and I found out a few things talking about allowing the SqlBrowser in firewall properties, done that...
allowing a connection to port 1433 and port 1434 through windows firewall, done that both.
Is there something Im missing or not doing?
Also it says "a connection was succcessfully established with the server" which means that It is able to connect, but something is going wrong somewhere. Also where it says "error occured during login process" could it simply mean I entered the wrong credentials?
I mean, when installing the SQLExpress I chose Windows Authentication so I never really got a username and password, So i just used the username and password for the Administrator account I use to connect to my server itself. Dont know It could have something to maybe just do with my login.
Could anyone please point me in the right direction as to why Im getting that error, even though I have enabled the TCP Connections and allowed SqlBrowser.
Any help would be greatly appreciated.
Thanks.
This is a bad certificate-related error, probably caused by different operating systems/environmental differences. If this is for testing purposes I'd disable the certificate, or you can configure it here (which is probably a good idea if you're creating a real application and not just playing around with it).
Please run the sql service and agent service by creating new id and start the service with that like ea admin or any other.
The port error will continue to show even if you fix the port ,check telnet configuration and enabled/open port via it.
I had similar problems so i created a virtual server installed sql server2008 r2 and then started it worked fine.
There are possibilities of error and authentication problems since we reuse the server by formatting it .
I have a strange issue. I can connect from one Terminal server to the SQL server as an admin. I can also connect to the server via a straight SQL connection as a normal user. When I try and log on to the server using odbc I receive the following error.
07/08/2011 10:49:14,Logon,Unknown,Login failed for user ''. Reason: An attempt to login using SQL authentication failed. Server is configured for Windows authentication only. [CLIENT: 10.0.0.25]
07/08/2011 10:49:14,Logon,Unknown,Error: 18456 Severity: 14 State: 58.
The SQL server is definitely in mixed mode and a user is definitely set up in the connection. It must be a permissions issue.
Probably the user that tries to login does not have permission to the database he/she is trying to connect.
Go to the SQL Server > Security > Select the User - Right Click > Properties > User Mapping
And there select the database that user needs to access (check box in the map column)
I'm pretty sure that error had happened to me before that that's how I fixed it. Assuming it is true that your server is setup as mixed mode already.
If your using ado.net, make sure your using the ODBC data adapter, connectors and odbcCommands instead of the SQL ones. ;)
I have a service that talks to local instance of SQL Server. I am getting an error
System.Data.SqlClient.SqlException:
A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)
This error happens intermittently. Since this is part of my continuous integration process its painful as I have to carry out whole build process again.
I would like to make this clear that I am not getting the issue every time its random in nature.
Please help me with this.
Have you tried toggling the various connection interfaces via the SQL Server Confoguration tool? I suspect you may be connecting via TCP/IP, which could be the subject of network issues elsewhere. Because you're local to the server, you could disable that interface and force the use of Shared Memory, which should help you troubleshoot the problem.

I have setup mirroring only with principle and mirror in untrusted domain environment using certificates. I have successfully tested the mirroring session by doing a manual failover. But I see a lot of login failures in the mirror server saying
Login failed for user 'NT AUTHORITY\LOCAL SERVICE'. Reason:
Failed to open the explicitly
specified database. [CLIENT: ]
SSPI handshake failed with error code 0x8009030c, state 14 while
establishing a connection with
integrated security; the connection
has been closed. Reason:
AcceptSecurityContext failed. The
Windows error code indicates the cause
of failure.
Login failed. The login is from an untrusted domain and cannot be used
with Windows authentication.
I am not using windows authentication for mirroring. Can someone please suggest the way to avoid these errors from appearing in the error log. Also why is the principle server still trying to use windows authentication?
Those failures are not from the mirroring connection. Those errors are from your client trying to connect to the mirror instance.
The first error is from a local service that is attempting to open an explicit database that is offline (perhaps is trying to connect to the mirrored database). The second error is from a client that had failed the SSPI handshake. And the third one is from a client that has succeeded the hansdhake but is not trusted.
You have to verify your client apps connection strings and, your agent jobs etc etc and see who is attempting these connections.
ok as follows: in the mirror monitoring tool you can set the connection / authentication it should use. Your probably best of removing the connections in the monitoring tool and reregistering them according to the accounts you have set in the endpoints.
