Can't See The SQL Server Express Instance On SQL Browser
Feb 8, 2007
Hi All,
I am using SQL Server Express to connect to the network using VPN on a local machine. I have done the following..
a.) Enabled the remote connections for the Express Instance and rebooted the machine.
b.) Connected to the machine with Express Edition locally and can also connect other SQL Server instances from it to verify connectivity.
c.) Yes, SQL Browser Service is running.
d.) Firewall is not turned on, so I do not have to configure any exceptions.
Now here is the big problem: When I browse for SQL Servers on the network the machine does not show up on the list, i.e "macinenameSQLExpress". I had uninstalled and reinstalled the Express edition and rebooted the machine several times with no luck on the SQL Express Instance showing up on the browser list. I even changed the default instance name to "machinenameMACHINE1" on one of the reinstalls. However, I can connect to other SQL Instances from it. But, I cannot connect to it from other machines since its not registered on the network. I have been working on this for the past few days by looking for a solution via this and other forumns. Is there some setting somewhere that I am missing that prevents this instance from not showing up on the browser list. This issue with SQL Express Edition is baffling as well as frustrating and any ideas that can resolve this issue is very much appreciated.
Please assist, the issue with SQL 2005 Browser and SQL 2000 Server Service is understood.
Our problem is with networked 2000 instances and SQL Express. The SQL 2000 machines (Standard & MSDE) do not have SQL 2005 or Express installed only 2000. When a SQL Express computer is put on the network with the SQL Browser service running almost all SQL 2000 machines lose sight of the other SQL 2000 instances. The second the SQL Browser is turned off on the SQL Express box the SQL 2000 machines can see each others instances. It appears that the response from the SQL Express SQL Browser causes the SQL 2000 machine to stop listening for responses. Once in a while one of the SQL 2000 instances will show up with the SQL Browser active on the network and it is my belief that it is because that response made it in before the SQL browser response. Please help as this does not appear to be a recognized issue. I'm assuming there aren't many sites running as many named instances on individual machines like we do.
Please note this appears to be a problem with SQL Express Browser not SQL 2005 Standard's which runs without problems on our network.
So, here is the scenario. I have a server that is running a MSDE 2000 instance (8.0.2039). Runs just fine. I install another database, this one is SQL 2005 Express (9.0.3042). Both are installed as part of application setups. Now, for various reasons, I have to uninstall the MSDE 2000 application and reinstall it. After the reinstall, the SQL Browser service no longer enumerates the MSDE instance, only the 2005 instance. As a workaround I fixed the MSDE port on the server and the clients, and it works fine. It also works fine when the application is run from the local computer without a fixed port.
I have been trying to drill down to the cause for this event log message: "The configuration of the AdminConnectionTCP protocol in the SQL instance SQLEXPRESS is not valid." It is reported from the SQLBrowser service as a warning when the service starts. I have tried starting SQLBrowser.exe with -c flag, but the output reveals no errors. I have seen this error on three computers. Two are running SQL 2000, 2005 and Express. One was only running Express, but still this message. I then looked into the log for the SQL Express server itself. It shows this message on startup: "Dedicated administrator connection support was not started because it is not available on this edition of SQL Server. This is an informational message only. No user action is required." Now, it appears to me that these two messages may relate to the same "error" (or rather behaviour by design). So, can anyone confirm that the warning in the event log from the SQL Browser service occurs becuase of that the SQL Express edition doesn't allow any "AdminConnection", but the SQL Browser service isn't aware of that SQL Express edition shouldn't support that, and reports it as a warning (implying that we can't do much about this warning)?
I'm trying to configure a named instances of SQL Server 2012 SP2 to have specific IP addresses and listen to that IP on port 1433. Alongside this, I have the default instance running on a different IP and listening to that on port 1433.I've managed to get them configured so that they are reachable using the IP, and looking at the log for each they are listening correctly on that IP on port 1433; in addition, the default instance connects fine using the SERVERNAME.However, when I try and connect to the named instance using the SERVERNAME/INSTANCENAME syntax, I receive the following:-
"Cannot connect to SERVERINSTANCE. Instance failure. (System.Data)"
Configuration for the TCP/IP protocol for that instance is as follows:-
Protocol Tab
Enabled= Yes Keep Alive = 30000 Listen All = No
IP addresses Tab
IP1 Active = Yes Enabled = Yes IP Address = 10.1.1.1 TCP Dynamic Ports = 0 TCP Port = 1433
[code]...
The SQL Browser service is running and prior to switching off Listen To All, I could connect to the instance remotely using the instance name.
For the first time, I want to set up the configuration of my SQL Server Management Studio Express (SSMSE) to allow me in doing the non-User-Instance/ADO.NET 2.0 programming from my VB 2005 Express. The SSMSE and VB 2005 Express are in my Windows XP Pro PC that is part of our NT 4 LAN System in our office. I read the article "How to configure SQL Server 2005 to allow remotre connections" in http://support.microsoft.com/kb/914277/ about (i) "Enable remote connections for SQL Server 2005 Express", (ii) Enable the SQL Server Browser service", (iii) Create exception in Windows Firewall, and (iv) Create an exception for the SQL Server Browser service in Windows Firewall. I entered the SQL Server Surface Area Configuration and I could not decide what options I should take for doing the non-User-Instance/ADO.NET 2.0 programming from my VB 2005 Express. I have the following questions on the page of "Minimize SQL Server 2005 Surface Area": (1) I saw "Configure Surface Area for localhost [change computer]". I clicked on [change computer] and I saw the following: Select Computer The Surface Area Configuration of this surface area of this computer or a remote computer. Specify a computer to configure: O Local computer O Remote computer Should I choose the "Local computer" or the "Remote computer" option? (2) Below the "Configure Surface Area for localhost [change computer]", I clicked on "Surface Area Configuration for Service and Connections", Select a component and then configure its services and connections: |-| SQLEXPRESS |-| Database Engine Service I picked => Remote Connection On the right-hand side, there are: O Local connections only O Local and remorte connections O Using TCP/IP O Using named pipes only O Using both TCP/IP and named pipes Should I choose O Local and remorte connections and O Using named pipes only?
Please help and tell me what options I should choose in (1) and (2).
Hi all, I have read/studied (i) Working with Databases in Visual Web Developer 2005 Express in http://quickstarts.asp.net/QuickStartv20/aspnet/doc/data/vwd.aspx, (ii) Xcopy Deployment (SQL Server Express) in http://msdn2.microsoft.com/en-us/library/ms165716.aspx, (iii) User Instances for Non-Administrators in http://msdn2.microsoft.com/en-us/library/ms143684.aspx, and (iv) Embedding SQL Server Server Express in Applications in http://msdn2.microsoft.com/en-us/library/ms165660.aspx. I do not understand the concepts and procedures to do Xcopy and User Instances for non-administrators completely-I do not know how to connect to databases and create database diagrams or schemas using the Database Explorer. I have a stand-alone Windows XP Pro PC. I have created a ChemDatabase with 3 dbo tables in the SQL Server Management Studio of my SQL Server Express and a website of my VWD Express application with an App_Data folder. I am not able to proceed to use Xcopy and user instance to bring the 3 dbo tables of ChemDatabase to my App_Data folder. Please help and give me some detailed procedures/instructions to bring the 3 dbo tables of ChemDatabase (or ChemDatabase itself) from the SQL Server Management Studio Express to the App_Data folder of the website of my VWD Express project? Thanks in advance, Scott Chang
i installed two servers, one instance SERVER05 and second SQL SERVER EXPRESS called SQLEXPRESS.
my SQL Server Browser service is in state "Change Pending" i dont know if it is ok?
I setup SERVER05: TCP/IP in Conf Manager Enabled, listen all yes, and IPAll TCP Dyn. ports nothing = blank, TCP PORT 2001 i think that SERVER05 is listening on port 2001 now. i restart SERVER05 and try this command: SQLCMD -E -S MACHINEASERVER05,2001 connect successful
I want to do this with SQLEXPRESS i set TCP enabled, Listel all, Dyn port blank, TCP PORT 2002 restart and get error:
Unable to start service MSSQL$SQLEXPRESS on server MACHINEA Additional information The MSSQL$SQLEXPRESS service on MACHINEA started and then stopped. (ObjectExplorer)
I have configured an instance to use static port, say 1435, and I turned off the Browser service.
I would like to know if I can use SSMSE to connect to the instance database directly. The instance is listening at port 1435 and accepting connection requests from other methods.
What I need to put into the "Server name: " field?
Normally, it would be like: <serverIP><InstanceID> with Browser turned on.
Now how do I add the port information to it, I tried
Herre is my connection string:<add name="PageEngine" connectionString="Data Source=MyServerSQLEXPRESS;Initial Catalog=PageEngine;Integrated Security=True;User ID=MyID;Password=MyPwd;" providerName="System.Data.SqlClient"/>When I run the app using WDE (Web Developer Express), Everything works fine. I can access and diplay data from the database with no problems. However, when I try to run it from a browser on the local machine or a remote machine it fails to create a datareader. I am using the Database factory from Enterprise Library. IDataReader dr = pe.DataReaderFromStoredProcedure("pe_GetApplicationInformation", null, "PageEngine");if (dr.Read() != false) (* this is the line it fails on every time){_ApplicationName = dr["ApplicationName"].ToString();_Version = dr["Version"].ToString();_Copyright = dr["Copyright"].ToString();_Owner = dr["Owner"].ToString();}dr.Close(); Here is the "DataReaderFromStoredProcedure" methodpublic IDataReader DataReaderFromStoredProcedure(string spName, peParameters parameters, string connection){Database db;if (connection != null)db = DatabaseFactory.CreateDatabase(connection);elsedb = DatabaseFactory.CreateDatabase();DbCommand dbCommand = db.GetStoredProcCommand(spName);dbCommand.CommandType = CommandType.StoredProcedure;Here is the error message I get:Object reference not set to an instance of an object.

Is there a way to re-index a SQL Server Express User Instance? If I try to open the .mdf while the website is still running, I get a message stating that the file is in use. If I shut down the web service and open the .mdf, then restart the website, then the website cannot access the .mdf while I have it open in VStudio (reminds me a lot of Access). In the past I tried to open a user instance with SQL Server Management Studio, but then it goofed up my user-instance...so I am hesitant to try that again. Is there any way to re-index? Thanks!
I'm new to SQL Server and just installed VS 2005 and SQL Server 2005 Express. My question is, is there any naming rules for an instance? When I open Express Manager it is asking me to enter an Instance name. Thanks for any suggestions or help,
Do the restrictions for SQL 2005 express apply to each instance or per server? For example, if there are two instances installed on a dual CPU machine, can each instance be configured to use 1 CPU and 1 GB of RAM?
I recently installed SQL Server and Visual Studio. When I went into SQL Server, I could only connect to a SQL EXPRESS Database engine. I need to access the full Database. I tried disconnecting it, uninstalling/reinstalling. Now I cant connect to the SQL EXPRESS DB Object. There are no SQL Server services running.
I have installed SQL Server Express and I can connect with it locally using "localcomputernameSQLEXPRESS". It is configured for remote connection and for some reason, when I browse for this instance on the Network Server, it does not appear in the list. I have unistalled/installed it several times and still I cannot see this instance on the SQL Network server list. Can anyone help troble shoot this frustrating issue...
The problem can be seen in Enterprise Manager for 2000 (all service packs), Service Manager for MSDE (2000 all service packs), and OSQL (2000 all versions). The exact problem is as follows: In a network environment if SQL EXPRESS (problem does not occurr with 2005 Standard) is installed using defaults SQL 2000 & MSDE machines will no longer see instances. This is a browser issue for 2000 and MSDE. For some reason the response back to the 2000 machine from the EXPRESS machine causes the 2000 machine to stop listening for reponses.
If you have a network with SQL 2000/MSDE machines that have named instances (default instance is not affected) they will lose sight of eachother when a SQL EXPRESS box is put on the network with its SQL browser service running. We have tried service pack 3a and 4 on the 2000 boxes and it does not resolve the issue. It may resolve issues with 2005 and 2000 on the same machine but this problem is with networked machines and doesn't appear to be the same issue. The SQL EXPRESS machine will be able to see all the named instances from the 2000 boxes and the 2000 machines usually will only see the EXPRESS named instance until the EXPRESS box SQL Browser service is stopped. No word from Microsoft so far.
DOES ANYONE HAVE A SIMILAR ENVIRONMENT AND RUN INTO A SIMILAR ISSUE?
I've set up a website on another computer using sql server express and visual web developer express, and it works as expected. However halfway through the development i've had to move to another computer. I installed visual web developer express + sql server express, and copied the project files across, but now when I attempt to run it I get the error:Failed to generate a user instance of SQL Server due to a failure in starting the process for the user instance. The connection will be closed. I've tried reinstalling the software and it doesn't help. Any idea why this is happening, and what I can do to fix it?thanks
how do I attach my user instance mdf and chagne scheme etc? for example my mdf is at c:sqldatamyapp.mdf
I tried attach and got
TITLE: Microsoft SQL Server Management Studio Express ------------------------------
Attach database failed for Server 'IEI-A64SQLEXPRESS'. (Microsoft.SqlServer.Express.Smo)
For help, click: http://go.microsoft.com/fwlink?ProdName=Microsoft+SQL+Server&ProdVer=9.00.2047.00&EvtSrc=Microsoft.SqlServer.Management.Smo.ExceptionTemplates.FailedOperationExceptionText&EvtID=Attach+database+Server&LinkId=20476
Hello, I'll try to make the description of this multi-problem scenario as short and sweet as possible.
First Problem The default named instance of "SQLEXPRESS" was somehow installed on my machine and nothing can get rid of it. However, it is somehow invisible to everything else on my system, so I can't use it. How do I get rid of the instance or repair it?
Second problem I installed another instance of the SQL Server 2005 Express and named it, "SQLEXPRESS02". I attached a database to it and successfully retrieved data from it using an application that used the following connection string:
Data Source=(local)sqlexpress02;AttachDbFilename=|DataDirectory|MyDatabase.mdf;Initial Catalog=MyDatabase;Integrated Security=True;User Instance=True
Next, I tried to use a different application to retrieve data from a copy of the same database located in a different directory and used the same connection string as that shown above. When I do this, I receive an error message similar to the following:
Database 'C:PathToMyOriginalProjectinDebugMyDatabase.mdf' already exists. Choose a different database name.
Cannot attach the file 'C:PathToMyNewProjectinDebugMyDatabase.mdf' as database 'MyDatabase'.
I then tried, out of curiosity, to change the Initial Catalog portion of the connection string to "MyDatabase2" and attempt the data retrieval again. The connection string looked like this:
Data Source=(local)sqlexpress02;AttachDbFilename=|DataDirectory|MyDatabase.mdf;Initial Catalog=MyDatabase2;Integrated Security=True;User Instance=True
Interestingly enough, it worked. However, when I switched back to the original connection string, I got the same error message as before.
What's going on here? I thought that one of the virtues of user instances was that they would attach at run-time, then disconnect when the application was through with them. If that's the case, then why am I getting errors stating that a database of the same name is already attached? Is there a way to detach these databases from a user instance? Can it be done by some value in the connection string?
If I create a database in SQL Express and then copy the MDF/LDF files and attach them to a machine running SQL Server 2005 Standard - will this new database have SQL Express limitations?
Are there good reasons not to do this and create the database in SQL Server Standard using scripts generated from the SQL Express instance instead?
Basically, I'm setting up a merge replication between Standard and SQL Express for a common database and I figure attaching a copy of the database created in SQL Express is the fastest way to get this started.
I am using the following C# code to establish a SQL connect to a SQL database file:
// connection string // attach a SQL database file to a local SQL server express instance string _connectionString = @"Server=.SQLExpress; AttachDbFilename=C:BalanceDatabase_1.mdf; Trusted_Connection=Yes; User Instance=True";
// using System.Data.SqlClient; SqlConnection _sqlConnection = new SqlConnection(_connectionString); // open the connection _sqlConnection.Open();
// do something
// close the connection _sqlConnection.Close();
So far, the connection works fine.
However, next, I want to copy the database file to another folder. So the following codes: // source database file name string sourceDatabaseFileName = @"C:BalanceDatabase_1.mdf"; // target database file name string targetDatabaseFileName = @"D:BalanceDatabase_1.mdf"; // copy database file System.IO.File.Copy(sourceDatabaseFileName, targetDatabaseFileName, true);
Then the program came with runtime exception: "IOException was unhandled: The process cannot access the file 'C:BalanceDatabase_1.mdf' because it is being used by another process."
Is it because the database file was sill attached to the local SQL Server express instance? What can I do to bypass this problem? Detach the database file? or dispose the local SQL Server express instance?
I just upgraded ACT database and it needs SQL Server. I just keep getting "SQL Server Setup Failed". I downloaded SQL from Microsoft, went to install and get the same error. It then refers to a summary txt log which I have had a look at but to be quite honest means nothing to me.
I get the following message after updating to sql server express 2005 advanced. Failed to generate a user instance of SQL Server due to a failure in starting the process for the user instance. The connection will be closed.
I noticed that in my C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLTemplate Data I have not databases? How do I get them back?
I also had to add back the aspnet to the permissions and the network and network service to the app_data folder.
I have been working around with SQL Server Express 2005 on VISTA. I created a small C++2008 application which interface with SSE 2005. When running my application, it automatically created a user instance which I would like to get rid of. I just forgot from start to set "User Instance = False" in my connectionstring. (oups...)
I'm aware, from readings I did, that a couple of tables as well as log files, etc. are created under directory "utilisateurs...AppDataLocalMicrosoftMicrosoft SQL Server DataSQLEXPRESS". SQLEXPRESS is the instance name chosen during install of SSE2005.
Also using following SQL Statement:
select owning_principal_name, instance_pipe_name, heart_beat from sys.dm_os_child_instances I got following result: owning_principal_name: PC-DE-STEPHANEStéphane instance_pipe_name: \.pipe6172F4E8-622E-4A sqlquery heart_beat: dead (at this moment...)
==> How can I make a good cleanup of all this as well as get rid of the user instance itself?
This is probably easy for some who have done it, but I have an installed Instance of SQL Server 2008 Express or SQL Server 2008 R2 Express I'll call Instance CCC and need to remove it. I have two other Express instances I'll call Instance AAA and Instance BBB. I want to uninstall Instance CCC without affecting the other two instances or the software that uses them. Instance CCC should have been installed as a SQL Server 2012 Express instance, so I need to remove the 2008 Instance of CCC and reinstall it as 2012. In all cases, I'm talking about SQL Server Express. Full SQL Server is not installed.
The Instances are all installed on a Windows Server 2008 R2 Standard server.
I have read that I can do this through Control Panel > Programs and Features, but that I can corrupt or mess up the other instances (AAA and BBB) if I don't do it right. I'm uneasy about this, not having done it before, and do not want to affect the users of the AAA and BBB instances!
The box I am trying to connect to is running two instances of SQL Server. There is a SQL Server 2005 instance which is the default. There is a SQL Server 2000 instance which is named 'SQLSERVER'. I can connect to the SQL Server 2000 instance no problem:<add key="ConnectionString" value="server=MYPCSQLSERVER;database=mydatabase;user id=****;password=****" /> However, I am having trouble connecting to the Default SQL Server 2005 instance. I have tried: <add key="ConnectionString" value="server=MYPC;database=mydatabase;user id=****;password=****" /> but it doesn't work. I have tried explicitly setting SQL Server 2005 to use port 1434 (as SQL Server 2000 is running on port 1433), and then used: <add key="ConnectionString" value="server=MYPC,1434;database=mydatabase;user id=****;password=****" /> but this doesn't work either.
Am I mssing something here? Any help much appreciated Thanks...
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.
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 ?
Hello there, We have a Windows Server 2003 where SQL Server 2005 is installed. The problem is that SQL Server browser cannot be started. When I try to connect to any instance of SQL Server, the connection fails. I have to try to start SQL Server browser and try to connect again to the particular instance of SQL Server after each attempt to start the browser. I succeed after several such attempts to connect, but SQL Server browser will still not start. Can anyone tell me what can be wrong with SQL Server browser? Thanks in advance Hemant
I want to move one database from the source SQL Server 2000 instance to a new SQL 2000 instance in another machine. I have five user databases in this source SQL instance. How should be my approach to move this single database out of this ? My understanding is restoring this database in the new instance, copying all logins to the new instance and then copying the jobs, DTS packages, alerts, operators only specific to this database will do it. Please let me know if this is exactly what I should do ..
