SQL 2005 Express Connection Problem
Jan 24, 2007
I'm a newbie to asp.net, but I have been a programmer for years.
I have a question that I'm hoping someone can give me a good answer
for, I have been trying to set up a site remotely and I've been using
the login control that comes with Visual Web Developer 2005 Express,
this comes with SQL 2005 Express. The remote site is not a company
computer, but basically a host that I'm paying for. When I deploy on
this remote site and try to log in I get this 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: SQL Network Interfaces, error: 26 - Error
Locating Server/Instance Specified)
Using the Database Explorer I noticed that on my laptop the database
file is sitting on my C: Drive. I also noticed that on the remote
server I deploy to has all my files on their D: Drive. My question is
do I have to set my SQL 20005 Express file up locally exactly the way
the file will set remotely? In other words... If, on the remote
server, my files will be on D:(url)asp_data... in order for my login
control to be able to use it, it has to be set the same way?
Also, does that remote site need to be set up with SQL 2005 express as
well? or will the site be able to work off of that file?
And Finally, I also have SQL Server 2000, if I wanted to use this login
control (the one that comes with Visual Web Developer 2005), how can I
reference this server instead of SQL 2005 Express? It seems Visual Web
Developer 2005 wants to use it automatically.
Thanks in advance

All --
Please help.
I have some questions about connection strings.
BACKGROUND...
Note that I am using the "SQL Native Client OLE DB Provider", SQL Sever 2005 Express, ASP.NET, C#.NET, and VS.NET 2005.
Note that I do not want to use the "Attach a database file" type of connection string.
Note that I am using the site http://www.ConnectionStrings.com as a reference.
Note that this "Standard security" connection string...<add name="LocalSqlServer" connectionString="Server=MYTESTOFFICESERVERS;Database=MyDatabase;Uid=MyDatabaseUser;Pwd=MyDatabasePassword;" />...does not work and causes the following run-time error...A connection was successfully established with the server, but then an error occurred during the login process. (provider: Shared Memory Provider, error: 0 - No process is on the other end of the pipe.)
Note that this "Trusted connection" connection string...<add name="LocalSqlServer" connectionString="Server=MYTESTOFFICESERVERS;Database=MyDatabase;Trusted_Connection=yes;" />...works but is less-than ideal because it uses a Trusted Connection rather than a Username/Password combination.
QUESTIONS...
(A) What exactly does the error in Item 4 mean?
(B) Do 4 and 5 imply that one must use a Trusted_Connection for all SQL Server 2005 Express connection strings when the database does not reside in the web application's App_Data folder or use a "Attach a database file" type of connection string?
(C) Are there any alternatives?
(D) What do you suggest?
Please advise.
Thank you.

Hi all,
I have SQL Server Express and VB 2005 Express installed in a Microsoft Windows XP Pro PC that is a terminal PC in our office Network. My Network Administrator has granted my terminal PC for Administrator Use. I tried to do the ADO.NET 2.0-VB 2005 programming in my terminal PC and I could not get a remote connection in the Window Form Application via Window Authorization. I do not know how to make this kind of remote connection in my Network. Please help and advise.
Thanks in advance,

Hi all,Just wondering if SQL 2005 express edition can be connected remotely. I've set up SQL 2005 Express on a separate machine and am having trouble connecting to it from VWD when creating the websites. Currently I've set up ASP.NET 2.0 Framework on the remote machine with IIS6 using Windows Server 2003 Web Edition. And I am directly editing the website remotely on the server machine from my PC. Could someone please help me in setting up a remote connection from VWD to the SQL Server?I've enabled TCP/IP setting in the SQL Configuration Manager but still getting errors. Could this be an issue with Express Edition? Because if it is I also have a copy of SQL Server 2005 to install. Any direction to resolve in this issue would be greatly appreciated.PS. I'm new to this so pls bear with me. Thanks.

I downloaded SQL Server 2005 Express and some sample databases (incl. Adventureworks_data.mdf), but when I try to Add Connection in VS 2005 to point to this db and use the Test Connection button, it gives the error:
---------------------------
Microsoft Visual Studio

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: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)
---------------------------
I've tried setting the data source as either "Microsoft SQL Server Database File" or "Microsoft SQL Server", but get the same error.
Any tips on verifying SQL Srv Express is installed correctly? Any ideas on how to solve this problem?
Thanks in advance.

Hi,
i am stuck in a strange situation.
I have successfully built my application setup through InstallSheild 12. Which first installs SQL Express user define instance as a pre-requisite and then install my application files. First time when i run my application (without restarting the pc), it connects successfully with user define instance.
But as i restart my PC and try to open my application, it is not connecting with database.
i am using the following command line to install SQL Express 2005 user define instance:
"/qn ADDLOCAL=SQL_Engine INSTANCENAME=MyInstance SECURITYMODE=SQL SAPWD="test" AUTOSTART=1"
if i change Remote connection to "using both TCP/IP and named pipes" through "SQL Server Surface Area Configuration" and then restart my pc again. My application connects successfully with Database.
Please guide me where i am getting wrong in building setup. do i have to add something in my command line to not get this error

I am having trouble connecting to SQL Server 2005 Express using ASP.NET written in VB.NET (1.1 Framework) in VS2003. I am trying to programmatically connect to the SQL Server. Since this is a redistributable web application and I don't want to rewrite the connection string every time I distribute a copy, is there any way to automatically get a connection string without prompting the end user for one? I can get the server name and the data base name, but I don't know how to get a username. It returns an error saying SERVERASPNET can't log on. Can anyone help?

I have the following problem, and any help would be appreciated. I am running sql 2005 on my production server, and developing websites on my development server running VWD and Sql Express.
I have been looking for the answer to this problem for about a week. When I upload my site to the production server I get sql errors on all the pages with dynamic content. I have looked into the permissions but nothing is working. Has someone had a similar problem and found a solution?
Thanks for any help.

Hi to all GURUS,
I am very (almost two days) new to SQL Server Express (in fact SQL Server). In my old applications I am using VB.Net 2005 Express with MS Access database and now I wants to go for SQL Server Express.
One thing I am unable to find till now is : if SQLServer Express is installed on my Server machine (say ServerPC) with attached database (say MyDB.mdf), how I can access it through ADO.Net 2.0 from client machine. (using VB.Net Express)
Thanks and hope you will encourge me to use SQL Server .

I just recieved an ASP script with SQL mdf file and I just installed the SQL 2005 express edition. I'm running it in mix mode (don't even undarstend what it means). The script works with the connection string pointing to the developers site.
connStr= "Provider=SQLOLEDB;Data Source=sql385.mysite.com;User Id=myID;Password=myPass; Initial Catalog=hra;"
I got a table called hra_DATA.mdf and a log which i was able to attach to them from the Microsoft SQL Server Management Studio Express panel.
How can i configure the connection to work with my server.
My servername and instance is MTL-SRV100SRV100
Thanks to all

I've just moved a website/database application from windows server 2000 and sql server 2000 to windows server 2003 sp2 and SQL 2005 Express SP2. Database intensive pages now take about 40 seconds where before they took 2-3 seconds.
Things I've tried that haven't helped...
- I changed the ADODB connection string
from: sCnString = "dsn=mydsn;Database=mydatabase;uid=myuid;pwd=mypassword"
to: sCnString = "driver={SQL Native Client};server=myserverSQLEXPRESS;Database=mydatabase;uid=myuid;pwd=mypassword"
- Checked that autoclose is false.
What else can I look at?

I try to use this conn string but it is not working I think the problem is with the provider
DataBaseSource = "Provider=SQLOLEDB; Password=sa2006; User ID=sa;Initial Catalog=coupon; Data Source=YAELSQLEXPRESS;"
I get error message
Microsoft OLE DB Provider for SQL Server (0x80004005)
[DBNETLIB][ConnectionOpen (Connect()).]SQL Server does not exist or access denied.
do you know which provider can I use?
or maybe it is a sacurity problem

I know this is an old problem that has been discussed many times but I'm having a problem getting connected to a remote SQL Express server.
I am running SQL Express 2005 on Windows 2003. I am trying to access it from Windows XP PRO. I have read all the articles about enabling remote access, enabling TCP/IP connection etc and have done that. I also created a user in SQL Express to allow for SQL-SA based authentication. I beleive that this my only option since the two systems are not in a Domain, they do not share common user names.
Using SQL Server Management Studio Express(SSMSE), I can see the instance of SQL, but have had no luck in attaching to it. I thought it might be a firewall problem, but I disabled them completely with no help(ZoneAlarm and Windows). The error message(below) seems to indicate that it can't see the specified SQL instance but I've checked the name multple time and I use the browse feature in SSMSE to identify it.
What am I missing? I've tried everything I can think of and I have made this work before so I'm not a total novice at it.
I would appreciate any suggestions...
Thanks

I am attempting to setup a SQL Server 2005 Express database as a backend to an Access MDB, and need to establish an ODBC data source for the backend database. On two different systems (Windows XP Pro and Windows 2003 SBS), I get an error that says I cannot connect to the SQL Server. I get a message that says:
Connection failed: SQL State 08001 SQL Server Error: 2
[Microsoft][SQL Native Client]Named Pipes Provider: Could not open a connection to SQL Server
That is followed by a Login timeout expired and a suggestion that under the default settings SQL Server does not allow remote connections.
I have shared memory, named pipes and TCP/IP protocols enabled, and the firewall set to allow connections on port 1433. And the Express manager seems to work OK.
I see several posts about issues with ODBC, but none of the suggestions seem to help in this situation. Can anyone suggest something to try? Thanks in advance.

Hello,
I am working on porting a Windows Forms VB.net VS 2003 app with a SQL 2000 backend - to using VS 2005 with SQL Express 2005.
I cannot seem to figure out how to set my connection string to work in the new environment. I have already recreated my database in SQL Express 2005 and ported the VS project to VS 2005.
The old string was (in my app.config file):
<add key="ConnectionString" value="workstation id=MAIN1;packet size=4096;user id=sa;data source=MAIN1;persist security info=True;initial catalog=Dbname;password=####" />
Any ideas?
Thanks,
Sam

This is a bit of a cross-post from the VS 2005 Forum, but we don't have a forum dedicated to SQL Server 2005...This is on my test machine running Windows XP Pro SP2 (NTFS),I have an existing SQL 2000 database located on a separate hard drive dedicated to data -- the e: drive.I just installed SQL Server 2005 Express, in the default installation directory (c:Program FilesMicrosoft SQL Server) and I cannot connect to that database on the e: drive. Named pipes, error: 40 (Remote access services are not installed by default).I don't want the database physically located on the c: drive.I've been looking all over for the solution for this, and can't find it.Advice or direction to reference materials would be appreciated.Tinker

Hello everybody
I`ve installed Visual C# 2005 Express edition for evaluation reasons. After that I also installed Microsoft SQL Server 2005 Express edition also for evaluation. I then downloaed the installation scripts for the Northwind database and tried to install them.
Unfortunately, every time I try to execute these scripts I get the error :
C:SQL Server 2000 Sample Databases>osql -E -i instnwnd.sql
[SQL Native Client]Named Pipes Provider: Could not open a connection to SQL
Server [2].
[SQL Native Client]Login timeout expired
[SQL Native Client]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.
I`ve enabled named pipes in the configuration utility, but to no avail. This is also no firewall problem. It just can`t connect to SQL server. Anybody with similar problems or a possible remedy?

Is it possible to connect to a sql server express over internet or not ?
- I am using a win2003 sp1 server. Freshly installed.
- The server is directly connected to internet.
- For the purpose of the test, I stopped the windows firewall and the IPSec service.
- I stopped SQL server Browser service.
- I find a free port (here : 1401)
- I activated TCP/IP protocol in SQL Server Configuration Manager, and I have selected 1401 as the TCP port in the IPAll sextion of TCP/IP protection (and I remove the '0' of the dynamic TCP Port).
- Restarted SQL server express...
In the sql server log, I get the message "Serveur Server is listening on [ 'any' <ipv4> 1401]"
But I never get an answer from the server.
sqlcmd -S ip_of_the_server, 1401 -U username -P password is working fine if launched on the server. But I always get a timeout error from any PC. Same with a telnet on port 1401.
Any idea ?

Any other idea?

Hi
I got an access 2002 application front end with a sql server 2005 express back end. Some of my clients are having some difficulties. After using the application for a while, some of the users are finding that the system just hangs up. It usually happens after the front end application has been running for about an hour (sometimes sooner and sometimes later). There are perhaps 1 to 5 concurrent users and I have checked to see if there are any firewalls stalling it (I think I check all of them)- Is there any way that SQL Server 2005 express could be caused to just stall- This even occurs with the odd laptop. All the appropriate protocols are enabled as well. These databses are not very large.
ANY HELP WOULD BE GREATLY APPRETIATED!!!
Thanks

Good day.
I am trying to look at a friends database that they have developed. Not having used SQL Server Express before I am experiencing problems trying to remotely connect to their database.
He connects locally just fine of course.
I get the error message about remote connectionsand the default settings so I have enabled TCP/IP and Named Pipes as well as cleared SQLSERVER Express in my firewall settings. I also stopped and restarted the service, but still get the same error message.
My connection parameters are like:
Server type: Database Engine
Server name: http://sql.exampledatabase.net (should http be here? have tried with and without same error)
Authentication: SQL Server Authentication (windows authentication? If so, how do I change to such?)
Login: http://username (should http be here? have tried with and without same error)
Password: password
TITLE: Connect to Server
------------------------------
Cannot connect to http://sql.exampledatabase.net
ADDITIONAL INFORMATION:
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) (Microsoft SQL Server, Error: 53)
Any help would be much appreciated.

I just installed SQL Server Management studio express. I am trying to remotely connect to a SQL Server Express 2005 remotely. I was given the server name, user name and password, and used SQL Server authentication. It connected fine, and I was able to get at the intended database.
I then went to ODBC data sources to add this SQL server using SQL authentication. I entered the server, user and password, and I got a nebulous "could not connect" error. I thought is may be because I still was connected in SQL Server Management studio express, so I closed it and tried again with the same error. I then reopened SQL Server Management studio express and tried to reconnect, and got the same nebulous error, and have not been able to connect since.
I tried rebooting and reinstalling SQL Server Management studio express, but had the same result. Does anyone have any idea what I may have done and how to undo?
Thanks,

Hey guys,
Hope one of you can help me. I've got SQL Server 2005 Express installed on a laptop. I'm trying to create an ODBC connection to it so that I can access the database from a program locally that will be writing to it. I can connect to the SQL instance by listing the server name as DSR-XXXXXXX(ComputerName)SQLEXPRESS
However... when I access that ODBC connection, it doesn't see the database DBProScout (which was created inside SQL Express on this laptop locally), and I cannot access the tables within it. The only tables that I can access are system tables associated with SQL Server Express.
What could I be doing wrong?
Thanks!

Preface, I am just starting to learn about database and web development.
I installed VS.net 2005 which updated my web site project file and automatically attached it to a database. It connected to ".app_dataaspnetdb.mdf". However it messed something up and the connection didn't work. If I create a project from scratch, it connects to its DB just fine, but not my upgraded project.
However, when I publish my web site, I need to use ODBC. So, my thought was to simply set up the system locally in a way that will make it easy to connect on the web site. I was told to add a system DSN to the "Microsoft ODBC Administrator". I tried to add a "SQL Server" and give it the database name but it failed to connect.
So, then I ran the SQL Server Configuration Manager and looked at the server properties and found this string under the advanced -> startup parameters.."-dc:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLDATAmaster.mdf;-ec:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLLOGERRORLOG;-lc:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLDATAmastlog.ldf"
My database is in an entirely different folder. The database it looks like it is servicing is a "master.mdf" database installed under the SQL server install folder. So, I figured that I found my problem. I just have to change this file to map to mine. I replaced these three strings with paths to my aspnetdb.mdf/ldf files, and created a LOG folder. Howwever, it wasn't able to connect to this database. It said something like "it doesn't exist or you don't have permission", even though I gave it the right path.
So, I'm at a loss for how to get my application to be able to use the ODBC interface to connect to its very own database on my local system.
What do I need to do? Please help!

Hi all,
When i attempted to connected to Microsoft SQL Server 2005 Express via ASP.NET 2.0 application, it seems to throw the following error.
I had set up the Protocols for Express (TCP/IP and Named Pipes are both enabled) to allow remote connections using both TCP/IP and named pipes.
Login failed for user ''. The user is not associated with a trusted SQL Server connection.
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: Login failed for user ''. The user is not associated with a trusted SQL Server connection.
Source Error:
The source code that generated this unhandled exception can only be shown when compiled in debug mode. To enable this, please follow one of the below steps, then request the URL:
1. Add a "Debug=true" directive at the top of the file that generated the error. Example:
<%@ Page Language="C#" Debug="true" %>
or:
2) Add the following section to the configuration file of your application:
<configuration>
<system.web>
<compilation debug="true"/>
</system.web>
</configuration>
Note that this second technique will cause all files within a given application to be compiled in debug mode. The first technique will cause only that particular file to be compiled in debug mode.
Important: Running applications in debug mode does incur a memory/performance overhead. You should make sure that an application has debugging disabled before deploying into production scenario.

Data Source=.SQLEXPRESS;AttachDbFilename="C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLDataAMSPROD_Data.MDF";Provider=SQLNCLI;Integrated Security=True;Connect Timeout=30;User Instance=True
I got error: No error message available, result code: DB_E_ERRORSOCCURRED(0x80040E21)
Then I changed the Provider to be like: Provider=SQLOLEDB, now I am getting the following error:
Message: "Invalid authorization specification
Invalid connection string attribute"
Source: "Microsoft SQL Native Client"
StackTrace: " at System.Data.OleDb.OleDbConnectionInternal..ctor(OleDbConnectionString constr, OleDbConnection connection)

Strange thing is, when I use the Connect To Database under Tool menu of VS.NET 2005, I could make the connection to this database. Then I copied this connection string to the code, the connection couln't be made. I feel very confused.
I am wondering if I need to add ASP.NET user to SQLExpress. But I don't know how to do it?
Can anyone please help me out! Many thanks!
