Can I Connect To SQLExpress Instance Using (local)

Feb 19, 2007

Hello,

I am using the following connection string to connect to SQL Server 2005 Express Edition installed on my local PC.
string sqlstr = "Server=(local);Database=MyDB;User ID=sa;Password=sa;Trusted_Connection=False";

And it gives me the following error. The string works fine in computer with SQL Server 2000 instance but fails with 2005. The string also fails for "Server = localhost".
However the string works very fine if I use the name of Server 2005 i.e ./SQLExpress

===================================

Cannot connect to (local).

===================================

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) (.Net SqlClient Data Provider)

------------------------------
Error Number: 2
Severity: 20
State: 0


------------------------------

 

Now the main problem is that, of course I could use a named instance, but since I am embedding the Connection String in a dll file so that any user can use it to connect it to the local instance of the SQL Server 2005 installed in his/her computer, I need to use "server = localhost". Doesn't SQL 2005 support this. If yes, where could i find option to enable it?

I have enabled every option available in surface area configuration for SQL Server 2005, but nothing seems to help out. I even use local as well as remote connections using both TCP/IP and named pipes.
Can nyone help me out?

Can't Get SQL Manager To Connect To Server Instance SQLEXPRESS

Jul 20, 2005

I installed SQL Server Express and SQL Server manager, then tried to start manager. SQL Service is running, but SQL Manager attempt to connect to SQL Server instance times-out even though I correctly identify instance as SQLEXPRESS? Everything seems to be normal - both SQL Server and Manager are on a single Windows  XP home machine. Any suggestions. Thanks

SQL Server Admin 2014 :: Cannot Connect To Named Instance (2nd Instance) From Local SSMS

Jul 22, 2015

I've two instances(Default, Named[dynamicsFINANCE]) running on SQL server 2014. However, when I try to connect to named instance say (dynamicsFINANCE) using SQL authentication from local SSMS, I get below error message:

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: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified) (Microsoft SQL Server, Error: -1)

I assigned a static port number to the named instance [dynamicsFINANCE] 1450. I also setup the firewall rule to allow access to Port 1450.

SQL 2012 :: Clustered SSAS Unable To Connect To Named Instance (instance Not Found On Server)

Mar 20, 2014

I have a 3 node cluster on which I have installed SSAS as it's own insntance. I have created this as a named instance and can connect to it by serverinstance if I'm on the server itself. However from my desktop I get the error saying instance was not found on server name.

I have defined an alternate port and setup firewall rules and can connect via server:port but not serverinstance. Prior to making this change SSAS was running on default port of 2383 and I could connect just by servername.

I have read many articles for previous versions saying that clustered SSAS will always use 2383 and that you must connect just using servername. However and this is were it gets strange. I have a 2 node UAT cluster with SSAS setup exactly the same way I've described above and I can connect from my desktop as serverinstance.

Should I be able to connect as serverinstances for a named clustered instance in 2012 ?

SQLExpress, User Instance And Detach

Feb 17, 2006

Basically I need to know how to detach a db from a user instance of SQL Express from inside a VS2005 windows forms application.

The application is project oriented and the design calls for each project to be stored in its own separate .mdf file. When the user wants to switch projects the application will detach the current database and attach a different one, containing the data for the desired project.

I have this working fine with the default (.SQLEXPRESS) db instance, but I am having a problem getting the code to work with a SQL Express user instance (also part of the specification).

I am using the SMO library to do the Detach, and this works fine with the default instance, but for the user instance I am unable to connect to the necessary (user) instance of the db server.

I have tried selecting the instance name from dm_os_child_instances on the default instance and using the dynamically generated instance name to create the Server object. I get a good instance name, but when I create the Server object, the connection fails. I have also tried issuing "sp_detach_db" on the user instance, but this fails because the db is in use.

Any ideas would be greatly appreciated...

(Problem) Named Instance As SQLEXPRESS?

Apr 13, 2007

What if I give my named instance as SQLEXPRESS? I read that SQLEXPRESS

would be the name of the DEFAULT instance if no named instance is given.

In such a situation how can I find out if its a named or the default one?

SqlExpress Instance In Connection String Instead Of Full Sql 2005

Sep 27, 2006

Hello, I had started my project with the express edition, then I switched to the pro one. The problem is that in my webconfig I still have  .SQLEXPRESS and I don't know how to modify that to use the full version of Sql server. <add name="MyConnectionString" connectionString="Data Source=.SQLEXPRESS;AttachDbFilename=|DataDirectory|MyDataBase.mdf;Integrated Security=True;User Instance=True"providerName="System.Data.SqlClient" /> When I look at the surface area manager I can see that I have 2 instances running : MSSQLSERVER and SQLEXPRESS.When starting Sql Server Management Studio I can connect to 2 servers: NEWDELL and NEWDELLSQLEXPRESS.And when I try to replace SQLEXPRESS by MSSQLSERVER in the connectionstring, then it doesn't connect.I remember having lost connection already when playing with all these tools, so I pay attention now ! That's why any help would be really appreciated ! Thank you.

SQLEXPRESS Instance On SQL SErver 2005 Standard Edition

Jan 10, 2007

What happens when you install a SQLEXPRESS instance on a machine that already has SQL Server 2005? Will the SQLEXPRESS still run in the limited mode or will it sense that an full standard version of SQL Server 2005 is already present and just "upgrade" itself?

On the otherhand, how do I "upgade" an existing instance of SQLEXPRESS to a full version of SQL Server 2005 standard edition without uninstalling and installing the standard edition. If I have both the instances then will the SQLEXPRESS be freed from its limits?

Thanks,

Vikram

The Configuration Of The AdminConnectionTCP Protocol In The SQL Instance SQLEXPRESS Is Not Valid

Mar 4, 2006

Hello,

I am getting the following warning in the Application Event Log:

The configuration of the AdminConnectionTCP protocol in the SQL instance SQLEXPRESS is not valid.

The warning is logged by the SQLBrowser service.

This is happening on Windows 2003 server with SQL Server Express 2005. On the same machine SQL Server 2000 is installed.

I am currently unable to connect from remote clients to the instance of SQL Express and I believe it has to do with this warning (I've tried all the usual remote connection troubleshooting without success - enabled protocols, SQL Browser Service running, there is no firewall on the server, I disabled firewall on the client when trying to connect).

Does anyone know how to resolve this issue?

If you need additional information please let me know.

Hello,

- The firewall part I am not so sure about. I am currently using Zonealarm....

3. I have installed SQL Server Management Studio Express(SSMSE) and attach the two database to it.

4. I have set SSMSE server properties to accept both SQL and window authentication.

5. I have made sure that both database "read only" setting to false

taDirectory|PhotoDataBase.mdf;Integrated Security=True;User Instance=True"
providerName="System.Data.SqlClient" />

and here is the new connection I just type in web.config that replace the original one:

providerName="System.Data.SqlClient" />

Can Connect To Sqlexpress But Not The DB ?

Oct 6, 2006

whenever i try and choose the database i wish to work with like below. I end up with an error message about the user not being associated with a trusted sql server connection

cnStr = @"Data Source=serverSQLEXPRESS;Initial Catalog=sqldata;User ID=blahme";

same with this one

cnStr = @"Data Source=STOCKYARDSQLEXPRESS;Initial Catalog=DB;Trusted_Connection=Yes;";

i figured this was all permission based so i kept dorking around with security adding my user name to anything i could find, and also went through and dozen or so connection strings and found when i take out the DB name that i can open a connection.... as the code below works...

cnStr = @"Data Source=ServerSQLEXPRESS;Trusted_Connection=Yes;";

cn.Open();

I plan on importing another database so how will i later on choose between the two, i notice i can create logins only at the security for the sqlexpress and not for my database? did i mess up how i created the database?
i have added my username and given permissions to the security for the database i wish to connect to, but is there another step im missing? i would keep trucking but i would like to have multiple DB on the sql express and pick and choose at the code level, maybe im misunderstanding what the catalog should include or i can change the connections database at another point?

Cannot Connect To SQLExpress From ASP.NET

Feb 22, 2008

I am trying to use built-in login authentication using SQLExpress (SQLMembershipProvider Class). I have run the utility "aspnet_regsql" both with and without the following switches "-E -A m". Either way it fails to connect and tells me I may need to enable remote connections. I have done that and set it to use both TCP/IP and pipes, even though the connection is local. I still get the same error message. If I open up SQL Server Manager, I can see that there is a user account set up for ASPNET.

Server Fails To Connect To SQLExpress

Dec 26, 2006

I am trying to set-up membership options on my MS Server 2003.

I also have a Computer running MS XP Professional sp2.

With the Advanced in stall of SQLExpress - trying to establish cojnectivity on the server fails when using the ASP.NET Configuration button.

This works fine on the XP box.

On the security tab the following message apppears:

There is a problem with your selected data store. This can be caused by an invalid server name or credentials, or by insufficient permission. It can also be caused by the role manager feature not being enabled. Click the button below to be redirected to a page where you can choose a new data store.

The following message may help in diagnosing the problem: Unable to connect to SQL Server database.

I've compared all settings in ssemee, surface manager etc. - all identical.

run aspnet_regsql on both machines. Added the SERVERASPNET account to SQLExpress and to the aspnetdb database.

I've enabled TCP,remote connections, named pipes etc. to no avail.

Any suggestion as to what the error could be would be most appreciated - been trying now for 3 days to get this working without any success.

Unable To Connect To SQLEXPRESS From A Client In A Workgroup (Error 40)

Jul 11, 2007

Hi to everyone!

Here is my problem: I have SQLEXPRESS running with Windows Authentication on a "server" PC named "ASUS1", and I need to connect from a "client" PC named "Presario1", user "Mauro", connected through a peer network (I use a cross-over cable); both PCs belongs to the same workgroup named "RMT-WORK", and they can see each others shared folders without problems.

I have installed the connectivity components + Management Studio Express on Presario1, and enabled named pipes and TCP/IP protocols; then I've got SQL Browser running. I have also added the Login "Guest" on ASUS1SQLEXPRESS.

When I start Management Studio Express on Presario1 and browse for servers I can select "ASUS1" as database engine but when I try to connect I receive "Error 40: could not open a connection to SQL Server" (same result using SQLCMD); I have tried to add on ASUS1SQLEXPRESS a user "Presario1Mauro" with "CREATE LOGIN [Presario1Mauro] FROM WINDOWS" but I receive a "Windows user not found" error...

Can anyone help me?

How Can One Connect (remotely) To SQLExpress Which Is Installed On Windows XP Home

Jun 27, 2006

Hi all,

I have to deal with a private network of laptops which are all equiped with preinstalled "Windows XP home"

I've installed SQLExpress on one of these, but I cannot connect on it from the rest of the laptops. (I've successfuly done this with "Windows XP profesional" though, and local connections work fine as well).

I've already setup the SQLExpress to accept conections throuigh TCP/IP but I can not think of something else. (Security comes to mind, but I do not know how to resolve it on "Windows XP Home").

Thank you

Ioannis

Can't Connect To SQL Server 2005 In Visual Studio, Only SQLExpress Works?

Jul 8, 2007

Hi all,I'm having a big problem here. I can't seem to connect to a database of MSSQL Server 2005... Here is what I've did:1. Under the Server Explorer>Data Connections. Right click and choose "Add Connection..."2. Data Source was "Microsoft SQL Server Database File". Click OK.3. I browse to the database in the MSSQL.2/MSSQL/Data folder.4. Click on the "Advanced" button, and change the default DataSource from .SQLEXPRESS to .MSSQLSERVER. Click OK5.  Received 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 setting SQL Server does not allow remote connections. (provider: SQL Network Interfaces, error: 25 - Connection string is not valid) Only .SQEXPRESS that I was able to connect to... i've tried the solution from Microsoft, opened SQL Server 2005 Surface Area Configuration and enabled "Local and remote connections", checked the option "Using both TCP/IP and named pipes" but it didn't help. This is frustrating because I can't get the Membership provider, login to work on my host. Please help. Thank you very much,Kenny.

Cannot Connect Remotely To SQLExpress Via SQL Server Management Studio Express

Oct 31, 2007

 Hi all, I'm having a little trouble connecting to a SQLExpress instance on a remote domain using SQL Server Management Studio Express.I've read that by default the program is set up locally only, so have edited the Surface Area Configuration.  It only gives me the option to edit 'Services and Connections' on the localhost, but have edited the Remote Connections to use TCP/IP and Named Pipes. In the Management Studio, I enter the server name, and login credentials.  On the Connection Properties tab I changed the network protocol to TCP/IP though everytime I attempt to connect I get the following error message:  Any help would be greatly appreciated. Rich

Help:SQLExpress User Instance Fails For Normal User; Works For Administrator

Jan 22, 2008

I'm using the RTM version of Visual Studion 2008 and SQLServer Express.

Logged in as an administrator, I can create a connection to an mdf file and all is well.

As a normal user, attempting to create a connection gives the message "sqlservr.exe has stopped working A problem caused the program to stop working correctly. Windows will close the program and notify you if a solution is available."

I have tried this with UAC turned on and turned off. The result is the same. In Services I can see that SQLEXPRESS is running, but each time I try to connect, I get the "stopped working" message.

For existing database programs that have the .mdf file stored in the project folder, I can run the program in the VS IDE on my XP machine and on my Vista machine as administrator, but not as a normal user.

I'm not looking for a workaround to make this work once, but the cause and solution to the problem. This is for an introductory VB textbook and we must be able to move a database program from one machine to another and make it work. Everything I have read says that SQLExpress should be able to do that.

Can anyone help me with this?

How To Connect To A SQL Instance In Another LAN

Dec 13, 2007

Testing a client application which needs to connect to a Analysis Services DB on a different LAN. The application needs to resolve a <server_name><instance_name> to connect however we keep obtain an error message such as "Errors in the OLE DB provider. Could not connect to the redirector. Ensure that the SQLBrowser service is running"

Using ODBC we can connect to the SQL Engine on the SQL Server on the remote LAN and all accounts used are correct, to my knowledge I have installed OLE DB Provider for Analysis Services 9.0 but configured nothing. Can anyone explain where I can set up a connection to Analysis Sevices via OLE DB, ODBC or any other method required to allow our client to connect. So far I'm unable to see any OLAP connection methods in ODBC, only SQL Server or Native SQL.

Any ideas?
