SQL Server :: Connecting To SqlExpress 2005 Remotely?
Aug 22, 2010So I've intalled SQL 2005 Express and Sql Server Management Studio Express (SSMSE). I don't have any problems connecting to it using Windows authentication. But I would like to set it up so that I can log in using Sql Server Authentication with a username and password.
But I'm getting an error message of "A connection was successfully established with the server, but then an error occured during the login process. (provider: Shared Memory Provider, error: 0- No process is on the other end of the pipe) (Microsoft SQL Server, Error: 233).
What I've done
I've created a new "Login" in the Security node. Provided all necessary role access level. Granted permission to connect to database and enabled login.
I've used the Sql Server Surface Area Configuration to set the Remote Connection type to "Using TCP/IP only" or "Using Both TCP/IP and named pipes" (tried both, but in either situation I get the same error message when attempting to login to SSMSE with the user name and password). I also made sure to restart the service.

View 2 RepliesDataSource Controls :: What Is Better: Connecting To DB With One Stored Procedure To Get Two Table At Once OR Connecting...
May 20, 2010While working with LINQ to ENTITIES I see that there is only a way to use stored procedure that is returning one entity only, or a view that is a join of two entities.
But what if I need in ASPX page to get two tables that there is NO connection between them, no join can be done between them at all.
I have one Stored Procedure that return the two tables, but entities don't support this right now.
I can split them to two Stored Procedure and call each of them separately.

View 2 RepliesSQL Server :: TCP Error When Connecting To SQL Server Via User Control
Feb 4, 2011We have a MOSS 2007 custom web part based on a user control that queries a database cluster. When the connection to the database is made, we regularly experience the error below and have had to create a work-around in the code to retry the connection. We have 3 environments - development, staging and production; the error only occurs in production. The difference in the production environment is it is a farm with 3 WFEs and a SQL cluster, where development and staging are single machine instances. All are MOSS 2007 & SQL Server 2008. We cannot find what is causing this issue and I'm hoping someone else has experienced a similar problem and knows the cause.
This is the error that occurs frequently when the query is executed:
System.Data.SqlClient.SqlException: A transport-level error has occurred when sending the request to the server. (provider: TCP Provider, error: 0 - An existing connection was forcibly closed by the remote host.)
at System.Data.SqlClient.SqlConnection.OnError(SqlException exception, Boolean breakConnection) at System.Data.SqlClient.TdsParser.ThrowExceptionAndWarning(TdsParserStateObject stateObj)
at System.Data.SqlClient.TdsParserStateObject.WriteSni()
at System.Data.SqlClient.TdsParserStateObject.ExecuteFlush()
at System.Data.SqlClient.TdsParser.TdsExecuteRPC(_SqlRPC[] rpcArray, Int32 timeout, Boolean inSchema, SqlNotificationRequest notificationRequest, TdsParserStateObject stateObj, Boolean isCommandProc)

at System.Data.SqlClient.SqlCommand.RunExecuteReader(CommandBehavior cmdBehavior, RunBehavior runBehavior, Boolean returnStream, String method)
at System.Data.SqlClient.SqlCommand.ExecuteScalar()
at [Our Namespace.OurMethod](String someParam)
More than one method will generate this, but this is typical code, note the retry work-around:
public static DataTable OurMethod(string someParam) {
const string query = "sp_OurStoredProcedure";
var resultsTable = new DataTable();
var connection = new SqlConnection { ConnectionString = OurDatabaseConnection };
var command = new SqlCommand(query, connection) { CommandType = CommandType.StoredProcedure };
var dataAdapter = new SqlDataAdapter(command);
var retry = 5; SqlConnection.ClearPool(connection);
while (retry > 0) { try { command.Parameters.Clear();
command.Parameters.AddWithValue("@someParam", someParam);
connection.Open(); dataAdapter.Fill(resultsTable); retry = -1;
} catch (Exception ex) { retry--; if (retry <= 0) {
LogError("Exception: DataAccess:OurMethod: *RETRIES EXCEEDED* " + ex, "error");
} else { SqlConnection.ClearPool(connection);
LogError("Exception: DataAccess:OurMethod: ATTEMPTS REMAINING " + retry + ". " + ex, "warning");
} } finally { dataAdapter.Dispose(); command.Dispose(); connection.Dispose();
} } return resultsTable; }
Connecting To Sql Server 2008?
Mar 6, 2010I have developed a web application in asp.net with C# in visual Studio 2005. And i used sql server 2008 as back end. When i run the program, it shows the following error..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: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)

Configuration :: Connecting To Whois Server
Apr 28, 2010I have written a method for getting information about the ip-addresses of visitors to my web site. The method is called from Page_Load. It connects to the Ripe whois database and gets information about the ip sent. Everything works perfectly when I try it locally using localhost, but as soon as I upload the code to my web host it stops working, and I get the following error message saying that it can't connect to Ripe. The code is exacly the same as I use locally. (The relevant code is included in the error message below). I tried to contact my web host to ask them, but they said it was beyond their expertise...

SQL Server :: Simultaneously Connecting To Db With VS, Website And SSMS
Aug 27, 2010I have recently combined my aspnet membership database and main website database into one database file, I'm happy with the schemas, stored procedures etc. (This is a development project not yet a production project.)
My problem is that I can no longer simultaneously connect to the database from Visual Studio if a user is logged in to the website.
EG:
Scenario 1: No user is logged in to the website. I can go to the Data Connection window in VS, choose "Add Connection" and then inspect the contents and schemas of the database. This is fine.
Scenario 2: A user is logged in on the website. I try to connect to the website in VS and get the error:
"Cannot open user default database. Login failed. "
Scenario 3: I am connected to the database in VS and nobody is logged into the website. If someone tries to log into the website they get the following error:
Cannot open user default database. Login failed.
Login failed for user 'NT AUTHORITYNETWORK SERVICE'.
So it seems from the above that there can be only one connection to the database at a time? However this was not the case before I combined the membership database with the main website database. I could always make changes as a user logged into the website and at the same time see those changes through the connection in Visual Studio.
Slow Query When Connecting To Linked Server?
Nov 18, 2010I've got this query UPDATE linkeddb...table SET field1 = 'Y' WHERE column1 = '1234' This takes 23 seconds to select and update one row But if I use openquery (which I don't want to) then it only takes half a second.
The reason I don't want to use openquery is so I can add parameters to my query securely and be safe from SQL injections. Does anyone know of any reason for it to be running so slowly?

Security :: Connecting To The Server Machine Failed?
Oct 21, 2010I was logging in to my app, but my app always takes me back to log on page, so I set a break point at 'If Not (HttpContext.Current.User Is Nothing) Then' to see if the HttpContext.Current.User is Nothing.
After I clicked log in button, my app was processing a while then pop up the error message.
The error message is:
Unable to automatically step into the server. Connecting to the server machine 'xxx' failed. The debugger cannot connect to the remote computer. This may be because the remote computer does not exist or a firewall may be preventing communication to the remote computer.
My app doesn't have any codes to ask connecting the server machine xxx and it is not suppose to connect to a remote server; and I don't know what xxx is for.
