Unable To Connect To Mssql Server Using Sql Express
Oct 13, 2006
Hi,
I installed Sqlexpress server 2005 and am able to connect to the server using the sqlexpress manager.
The connection parameters are:
server: 127.0.0.1 (This is an alias name pointing to TMD03SQLEXPRESS)
username:sa
password:test
mode: sql server and windows authentication mode
TCP/IP : enabled and listening on port number 1433.
But I am not able to connect to the server using PHP's mssql_connect function.
but none of them works. I also tried OSQL and SQLCMD and they don't work either. They give me the following error message.
[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.
Can anyone please let me know what am doing wrong here?
i have installed MS SQL Server Express 2005 on my local machine. Also the managment Studio. I can connect to the MS SQL Server Express 2005 with my c# programm and with the mangament studio.
I have in Windows/system32 the file ntwdblib.dll version 2000.80.2039.0. The TCP/IP and Ip Protocl are active. But i cant connect with php to the local MS SQL Server Express 2005.
My php code is:
mssql_connect('192.168.0.2,1433', 'martin', '');
I get the return code Warning: mssql_connect() [function.mssql-connect]: Unable to connect to server: 192.168.0.2,1433 in c:InetpubwwwrootProjekteSkriptemssql_connection.php on line 2
Does anyone know what i made wrong or i have forgotten?
just installed a new machine with windows 2003 server and SQL SERVER EXPRESS; I am able to connect to the SQL Server using my windows credentials however I am unable to log on to it using 'sa' (and no password) user; i get the following error message.

I'm trying to connect a DB in SQL express with a program in VB.NET Express. I'm using the Data Source Configuration Wizzard. When I select the file (.mdf), the following message appears:
Unable to open the physical file "path to my file". Operating system error 5: "5(error not found)".
An attempt to attach an auto-named database for file 'myFile' failed. A database with the same name exists, or secified file cannot be opened, or it is located in UNC share.
I'm using the Windows authentication for this, but if I try with the sa user, I get the following message:
Failed to generate a user instance of SQL Server. Only an integrated connection can generate a user instance. The connection will be closed.
Hi, I am trying to connect with Database.mdf(Server Express) which is inside App_data with my ASP.NET website but i am receiveing an error which i have pasted below. Initially i tried using a business Object(.xsd) but while specifying the datasource in DataSourceobject i got nothing using wizard(which lists all the Adapter Methods(insert,select) of my business object) hence i am trying to connect without a business object. i.e just using the connection string(ConnectionStrings:DatabaseConnectionString) but this results below Error.

I have read all of the posts regarding this subject as well as 3"Dummies" guides and I keep having the same problems. I have a verysimple multi-user application that has to hit a database. Wecuerrently have this system deployed and it is working fine on adomain based network. We are scaling back and the network we will beusing is now a workgroup not a domain.It should be simple. I have XP boxes (clients) trying to hit the SQLServer Express database on a Windows Server 2003 machine. It is aclosed network so security is not an issue. I am trying to make thisthing wide open. All I want is for the user to be logged in on hisclient machine, run the application, and access/update the databasewithout having to re-authenticate to the SQL server. I want windowsto handle all of the authentication between the XP machines and theServer 2003 machine.Any suggestions would be greatly appreciated.
My situation: I have one virtual folder on a customer's server that hosts a web service which connects to Sql Server Express. This has been working for months.
The connection string that i use is: (obviously the names have been changed to protect the innocent) User ID=auser;Password=apassword;Initial Catalog=acatalog;Data Source=0.0.0.0SQLEXPRESS
I have recently added another virtual folder to the server, and it needs to connect to the same sql server. In this case it is a "regular" web site. I have it set up to use the same connection string as the web services site ( I can't think of any reason why it wouldn't be the same), however when I try to open the connection ( when I call mySqlConnection.Open(); ), I get get this error:
I am stumped as to why code in one virtual folder has no problem, while the other does. Both virtual and physical folders are on the same machine, and the Sql Server Express is installed on that machine.
I'm running SQL Express on Server 2003 SP1 (workstation - although, I did dcpromo promote and demote prior to installing SQL Express).
I'm trying to connect from SQL Studio Express on Vista.
TCP and Named Pipes are selected in Surface Area Config; sp_config remote, access..., 1 was run (per KB); ports 1433 & 1434 are open (I think 435 also was opened when I ran the KB instructions); Mixed mode is selected, user is set for SQL Auth, password is correct; all permissions are granted.
I found an article online which stated that mixed versions of MDAC can lead to the problem. The server has 2.82.1830 and the client has 6.0.5600.16834. Could this be the problem? If so, how to solve?
What could be the possible reason for this and how can i configure sql server 2005 express edition to make connections without specifying any portnumber in the connection string. Both the sqlserver database service and browser services are running.
I am trying to connect to sql server from a small c++ program , I am getting the following error
An error has occured when establishing connection to server. The failure may be caused by the fact that under the default settings does not allow remote connections.(Sql network interfaces error no 26 error locating server instance specified )
I chkd the default settings and it allowed remote connections. I also have default instance for the sql server
I am trying to connect to another computer in my local network which has Windows XP installed. It has SQL server 2000. I get an error message 'Time out period elapsed' when i try to connect to SQL server 2000 thru SQL Server Management Studio Express' Please guide.
I have a c# application running on my machine. I want to point to a sql server data base express edition running on other machine. By default, from server explorer Ionly acces data base files of the local machine. I dont have acces to remote servers.
I used the file explorer and opened the mdf file on remote server. I tried to acces the mdf file remotely but i got excepcion.
My questios are:
- Is sql server 2005 express edition supporting remote connection to mdf data base file?
- In other words, I can remotelty conncect to mdf file from remote machine ?
So, I how can point my application to remote sql server 2005 express edition data base running on other machine?
Cannot someone please help me with following problem. I am trying to create a program to update a sql datbase from.NET 2003. I am doing this by using SQL Server Express 5. The problem is, is that when I run the program and click the button to view the table in SQL Express 5 I keep getting an 'System.NullReferenceException' and the table is not shown. When I look at the debug details it says that 'object reference not set to an instance of an object'. Am not sure where am goin wrong as the connection is opened to the local server in SQL Express and I have created a connection object and initialised it to the address fo the datatable in SQL. Please find below the code I am working on which shows the connection string in question and the table being called in button 6 which causes the exception. Any help would be greatly appreciated....thanks

Hello I am able to connect to the server and most of the time I can't connect. It is important to be able to connect so I can manage my mdf - database. To test ... I disable the firework but I still can't connect 90% of the time. Thank you in advance. ~ Peaches ~
Hi, I have VS Pro 2005 and SQL Server Express 2005 installed on an XP Pro machine. When using VS 2005, in the 'Server Explorer' window I can see and attach to two SQL Server databases that I have set-up. But if I attempt to access the same databases from withn the 'Solution Explorer' window I get the following dialog box message,
" Required Component Missing (Dialog box heading)
Connections to SQL Server Files (*.mdf) require SQL Server Express to function properly. Please verify the installation of the component or download from the URL: http://go.microsoft.com/fwlink/?LinkId=49251 "
I have uninstalled and then reinstalled both VS 2005 and SQL Server Express twice but it has helped.
I don't understand why I'm getting this error because all of the server configuration tools and connection utilities seem to work fine but VS say's that SQL Server Express is not installed.
Thanks,
CLN
P.S. I had another application that required MSDE 2000A to be installed. When I removed the other application I also removed MSDE 2000A and that's when the problem began.
I've never used SQL Server before. I installed VB 2005 Express (I've been working with VB since I was 16), and SQL Server 2005 Express.
I installed the server with all the default settings and created a small database to handle customer information (a remake of some Access and Oracle databases I've made before).
I'm told, however, each time I try to connect to the database via VB, that SQL Server isn't accepting remote connections...
Remote? It's on a local computer. So is VB...what is going on here? Is there a setting I've missed?
Within SQL Express 2005 running on Windows server 2003 using asp.net as the interface
This Is the Situation, at first i recieved this error "
Previously we received a €œfailed to generate a user instance of SQL due to a Failure in Starting the process for the user instance. The connection will be closed€?
I looked up this error and it seams to be a flaw/bug in sql server express the error occurs because of the use of remote login on the windows 2003 server.
The solution to this was to delete an sql server directory that resides here C:Documents and SettingsUSERNAMELocal SettingsApplication DataMicrosoftMicrosoft SQL Server DataSQLEXPRESS.
This indeed solved the failed to generate a user instance once the server was re-started however now I get a responce within the asp.net pages (which will have been built into those pages)
Your login attempt was not successful. Please try again.
now i have checked the simple errors caps lock etc and tried to log on to the SQL pages directly on the server with exactly the same result. the system was built by somone else and has not been modified "intentionally" just recently i added a few extra databases to the same server location, could this have caused the problem. to my knowlage (e.g i cant recall changing any settings)
there are one or two extenuation circumstances just recently the whole file directory was transfered from one HDD to another and then back to it's original position now i dont think this altered data but possibly there is some inbuilt security or something, i would most sincearly appreciate any questions or answers about this possibly things i havent mentioned that you need to know, just let me know i will get back to you
Problem: I upgraded a SQL Server Express instance to SQL Server Enterprise, but I'm unable to connect to the SQL server from any remote machine. Only local connections work -- and I've verified that Remote Connections are allowed in the SQL Surface Confg. utility.
Scenario: Server1 has an SQL Enterprise edition installed as a default installation. SharePoint Server 2007 was installed later, and during that install a SQL Express edition instance was installed which is part of the standard SharePoint install. That Express instance contains all the SharePoint content databases.
So Server1 has SQL instances: Server1 <default install running Enterprise> Server1OFFICESERVER <previously running SQL Express, now upgraded to Enterprise>
After upgrading Server1OFFICESERVER to Enterprise, everything seemed to work fine (i.e. SharePoint works fine). However when I try to connect remotely to Server1OFFICESERVER I can't. I've verified through the SQL Surface configuration tool that remote connections are allowed. I've rebooted the server as well. I've tried connecting remotely using various PCs and various applications (e.g. SQL Server Mgmt Studio, Visual Studio, etc.).
I have recently changed my NT password and since then one of my machines has not been able to start MSSQL server. When I re-boot the machine it lets me know that it was unable to start MSSQL server. If I right click on the SQL server group in EM and try to manually start the service, it tells me that I have a login failure. I don't understand how changing my NT password would affect one machine and not the others. When I right click on the "edit SQL service registration properties" tab, all of the machines are using the NT password selection as opposed to the SQL server authentication password. Any ideas would be greatly appreciated
I'm having a problem connecting with a Java application but I CAN connect using my .Net application - the user name and password are the same for both (using the same database on SQL Server Express 2005).
The error I get is: "com.microsoft.sqlserver.jdbc.SQLServerException: Cannot open database "CORNERS" requested by the login. The login failed." An interesing note - I get the same message if the database is not running.
SQL Server Express 2005 is installed in mixed mode.
Here is my connection string in the .Net appplication: <add key="connectString" value="Server=(local);UID=sa;PWD=myPasswd;Database=CORNERS" />.
I upgraded my 6.5 server to 7.0 two days ago running into small problems with the database upgrade wizard. I had some small problems with security which took me some time but was not that difficult once I figured it out. I then proceeded to switch back to 6.5 mode to transfer all the data that had been done that day to my development machine so I could then import it to the SQL 7.0 version. When I was done with the transfer I switched back successfully, started the server successfully, but I was unable to connect. I get the error "Connection could not be established...", so after several attempts to connect and shuting the server down I now am at a loss. The server runs fine in 6.5 mode but it will not connect in 7.0?? Tonight I am going to try to reinstall SP1, if that does not work I am going to try to reinstall SQL 7.0. Any suggestions???
On a fresh installation of SQL Server 6.5, I have opened the EM and registered the server but am unable to connect. I get the error of 'A connection could not be established to [ServerName]- [DB-Library] Unable to connect: SQL Server is unavailable or does not exist. General Network Error. Check your documentation.'
I've tried connecting with all different DB-Lib settings to no avail. Ultimately, I want to use TCP/IP. I am, however, able to connect to other SQL Server boxes from this EM, just not the local server. I am able to stop and start the services from Control Panel and from SQL Service Manager.
Since I haven't been able to log into the local SQL Server, I've registered the server in EM to log in with sa and a blank password. I've already completely uninstalled SQL and reinstalled it to see if that would help. It didn't.
Does anyone have any idea what the problem could be?
I am running SQL 2000 on Windows 2000 Server. The clients are running different OS ranging from Win 98/NT/2000. Although i am able to connect to the local host, but whenever i try to connect over the network the following error pops up :
unable to connect to server <server name> Server : Msg 11, Level 16, State 1 [Microsoft][ODBC SQL Server Driver][TCP/IP Socket]General network error. Check your network documentation.
I checked up the event long on the server and found the following entry:
Event Type: Warning Event Source: MSSQL$NETSDK Event Category: (8) Event ID: 19011 Date: 1/20/2003 Time: 2:12:32 PM User: N/A Computer: <computer name> Description: The description for Event ID ( 19011 ) in Source ( MSSQL$NETSDK ) cannot be found. The local computer may not have the necessary registry information or message DLL files to display messages from a remote computer. The following information is part of the event: (SpnRegister) : Error 1355.
May i further clarify that this error started today n till last week end (saturday, i am
stationed in India) there was no problem and the users were able to connect to the server
without any problem. My network engineer feels that its an sql problem and has nothing to do with network related issues.
i would appreciate if anybody could help me out. thanking in advance
recently i made my PC dual boot by installing windows 2000 advanced server. It already had win2000 profesional installed on it. since then i have been unable to connect to sql server running on some other server(called CONTROLS) on the LAN. I am able to access the CONTROLS server thru 'my networkplaces' and able to see all its hsared directories and access htem. but when i open Enterprise manager i cannot connect to CONTROLS. Please help me . i have already wasted 2 days over it.
I am unable to connect to SQL Server using isql_w or enterprise manager. The ODBC settings register successfull and the services show as started. I have tried starting SQL server in single-user mode with minimum config to see if memory is a problem but still cannot connect. The error logs show SQL as having started successfully with no errors. Has anyone got any ideas?
From my Win98SE box with MDAC 2.6sp1, I can't connect to SQL (win2k, sql2k). I've tried everything I know but nothing works.
I always get the following error: Unable to connect to server 192.168.1.2 ODBC: Msg 0, Level 16, State 1 [Microsoft][ODBC Sql Server Driver] Timeout Expired
some additional info... - both computers are in a workgroup, not in a domain. - this is a home network and they're connected via a Linksys cable modem router - another box on this same lan can connect to sql just fine, although it's running win2k. - all boxes have identical DSN, Subnet...settings - I also installed Jet4.0sp1 just in case, but that didn't help either - I'm primarily trying to connect via TCP, although I have tried Named Pipes as well - i can ping both boxes from each other just fine - odbc ping fails
MDAC has worked beautifully for me for the last several years. Did MS change something recently...or is there another problem?
Hello. I am very new to SQL Server. I've tried to look through other posts on the forum but did not find the solution I needed. Please help.
I have SQL Server running on Machine1 which I am able to connect to. What I want to do is connect to this server through a Machine2 that is on my network.
Both Machines run on WindowXP Professional
On the server of Machine1, I have: 1. Under the security tab, I have created a New Login using SQL Server Authentication (general tab), checked all server roles (server roles tab) and checked to permit all databases (in the database access tab) 2. On the server, went to properties -> security tab and allowed for SQL Server and Windows authentication
On Machine2 when I try to register the server of Machine1 through the Register SQL Server Wizard, I am able to see the server. However, when I use the newly created Login Name and password (from step 1 of above). I get a Login Failed for user message. When I try to connect to the server through Query Analyzer I also get an unable to connect to server message (Server: Msg 18456, Level 16, State1)
If you place an image of your server on a rebuilt server, rename it andchange the SID. You get an error message “UNABLE TO CONNECT” when youuse the SQL Query analyzer on a desktop computer to connect to theserver (hosting the image). If you add the server (hosting the image)to the Windows2000 server domain/active server and restart the server(hosting the image), you get the following error message: "YOUR SQLSERVER INSTALLATION IS EITHER CORRUPT OR HAS BEEN TAMPERED WITH (UNKNOWNPACKAGE ID). PLEASE RERUN SETUP."Wouldn't you think changing the name, the sid and adding it to a domainwould be enough to access it. I even created a new ODBC connection.*** Sent via Developersdex http://www.developersdex.com ***Don't just participate in USENET...get rewarded for it!
