cannot connect to SQL Server 2005 Express

Posted By:      Posted Date: May 22, 2011    Points: 0   Category :


I am in the process of migrating a website running ASP with SQL Server 2000 to SQL Server 2005 Express.

I have installed the data, and fixed the problems with orphaned users (I think).

I can access the data using SQL Server Management Studio Express

However I cannot establish a connection from any of the ASP or ASP.NET applications. At first I thought it was just the connection string (using SQLOLEDB) but then I tried to set up a data source using ODBC with either the SQL Server or SQL Native Client driver. I have tried this on a remote machine (it is set up to allow remote connections), and also on the local server. The "Create a New Data Source" returns with the error "Specified SQL Server Not Found"

I am using (IPAddress)/SQLEXPRESS as the server name (I have also tried localhost and when trying to connect locally.

When using the "Create New Data Source" locally I have tried connecting as one of the database users, and as sa, and using the local network account (which is used to run SQL Server Management Studio Express.

I have disabled the firewall.

I have checked that TCP/IP is enabled using SQL Server Configuration Manager

Port 1433 is open.

Could anyone assist me in this ?

Thank you in advance

Access 2007 upsizing wizard can't connect to SQL Server 2005 Express


When trying to use the Access 2007 upsizing wizard to move a database to SQL Server 2005 Express, I get the following error message:

Connection failed:
SQLState: '01000'
SQL Server Error: 2
[Microsoft][ODBC SQ Server Driver][Share
Connection failed:
SQL Server Error: 17
[Microsoft][ODBC SQL Server Driver][Shared Memory]SQL Server
does not exist or access denied.

I get the same message regardless of whether I configure SQL Server to run as a local system or service.

I am the only user on my Vista 32 PC and am therefore the administrator. As far as I can tell I have sufficient authority since I can start and stop SQL Server.

As a newbie to all this, I can't find any step by step instructions as to how a local copy of SQL Server should be configured to work with the upsizing wizard. In fact I can't even find any Access 2007 help walk-throughs on this upsizing wizard, let alone troubleshooting its error messages.

Any help would be appreciated, as well as links to step by step instructions (which I can't find in the MSDN Library materials).

PS Does MS understand how inadequate and inefficient its built-in documentation really is? Maybe that's what keeps MS Press in business!

I went in Tools>Opetions>DataBase tools>Data Connection>Sql Server Instance Name (blank for default)

Multiple XML files into SQL SERVER Express 2005

Hello. I am familiar with classic ASP and use this with MS SQL SERVER EXPRESS. I have an SQL table and want to import multiple XML files into this on a daily basis. I currently have 3 files, transferdata.vbs which loops through the XML files. FAQschema.xml which maps XML to the SQL database and test.xml shows the xml in the test file. If I run transferdata.vbs I get the following error "Error opening the data file" line 33 char 3. Microsoft Bulkload for SQL Server". My SQL table is called EnqOrd id (int), Debitor (varchar), PurchaseDate (varchar)     transferdata.vbs set objBL = CreateObject("SQLXMLBulkLoad.SQLXMLBulkLoad") objBL.ConnectionString = "Provider=SQLOLEDB; Data Source=XXXXXX\XXXXX; Initial Catalog=XXXX; User ID=XXXXX; Password=XXXXXX" objBL.ErrorLogFile = "E:\fuelsql\Teccom\error.log" ' Here is the path to your XML files Const path = "E:\fuelsql\Teccom\XML\" Dim Text, Title, oFile Dim fso, oFolder, oFiles, wsh ' Object variables Text = "Folder " Title = "XML Files" Set wsh = WScript.CreateObject("WScript.Shell") ' Create FileSystemObject object to access the file system.

SQL Server 2005 Express Edition Service Pack 3 (KB955706) update is successful but repeats installin

  Microsoft SQL Server 2005 Express Edition Service Pack 3 (KB955706) (update 1 of 1) This update seems to be stuck in a loop of installing, each time it successfull installs acccording to automatic updates. Then says it requires installing again straight away. This has been happening for 10 days now. I have tried a manual update from the website rather than automatic updates, no change. Any ideas why? Have posted in Windows update which is where I think the problem lies but they have suggested I post here also.

Microsoft SQL Server 2005 Express Edition Service Pack 3 (KB955706) - will not download.install on W

This has all ready taken me hours and hours of my time with no success (after following the fixes mentioned on this site). I look forward to suggestions at to how to proceed that may actually work. Many thanks cdbc81

Can't connect to SQL 2005 Enterprise using Management Studio with Server Name (only (local) works

This is a test system, everything running locally & no domains. Win 2003 Ent. Server & SQL Server 2005 Enterprise. I can't log into SQL Server Management Studio using the server name & using either Windows Authentication or SQL login. If I change the name of the server in the drop-down list to "(local)", I connect just fine (both Windows & SQL security modes). Shared Memory, Named Pipes & TCP/IP enabled in both server & client. Remote connections allowed. I have IP adresses (both & external IP) in my hosts file pointing to the server name. Does SQL require a DNS server? This wouldn't be a problem except for the fact that I can't install SQL 2005 SP3 due to authentication failure since there's no way to enter (local) as the server name. SQL tools (management studio, SP install) seem to see the SQL server running but won't authenticate the user through any means other than setting server name to (local). This is driving me crazy!!!

SQL Server Express 2005 SP3 Bootstrapper

Hi Guys,I am currently in the process of creating a bootstrapper for SQL2005 Express SP3 so I can slip it into a Visual Studio 2008 setup project.Here's what I did:1) I copied the SqlExpress-SP2 folder (C:\Program Files\Microsoft SDKs\Windows\v6.0A\Bootstrapper\Packages\SqlExpress) into a new folder (C:\Program Files\Microsoft SDKs\Windows\v6.0A\Bootstrapper\Packages\SqlExpressSP3)2) I replaced the eula.txt and sqlexpr32.exe with the new SP3 ones.3) I changed the following in product.xml:<Product xmlns="http://schemas.microsoft.com/developer/2004/01/bootstrapper" ProductCode="Microsoft.Sql.Server.Express.9.3">4) I changed the following in package.xml:<PackageFile Name="sqlexpr32.exe" HomeSite="SqlExprExeSP3" PublicKey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    <Strings>        <String Name="DisplayNam

Which SQL Server 2005 Express Edition Service Pack to Install?

I have Windows 2008 Small Business Server Standard Edition.  When I scan for updates I get two different SQL service packs showing up, with the same KB955706 number.  I'm wondering which I should install, or if both, what order to install them in?  The first one is labeled: Microsoft SQL Server 2005 Express Edition Service Pack 3 The second one is labeled: Microsoft SQL Server 2005 Express Edition with Advanced Services Service Pack 3 For applications, I have Blackbaud The Financial Edge v7.78 (accounting package for clubs) installed that uses SQL Server 2005 Express Edition for its database engine.  The new upgrade for this software requires SP3 which is why I need to know which service pack to install.  Also, please let me know if there are any tricks to getting the service packs installed on 2008 SBS Standard Edition.  I know sometimes registry settings need to be changed for SQL service packs to be installed properly. Thank you for your help.  

Unable to connect to SQL Server 2005 remotly, all client protocols are blank

I have an installation of SQL 2005 and had issues connecting remotly. Looking at the client protocolols, they are all blank. I can see that TCPIP, Named Pipes, VIA, etc. are 'enabled', but where the words 'TCPIP', 'Names Pipes', etc. should be, it's just blank. I tried to install SQL 2008R hoping the Client Protocols would be corrected during the installaion, but they were not. I'm assuming the issue with the Client Protocols not showing up is a symptom of the problem. Does anyone have any ideas? Thanks!

Connection to SQL Server 2005 Express?

Hi all, I've been reading other posts for awhile now and I can't figure out what I'm doing wrong. I'm a Web Developer and not a DBA. I have SQL Server 2005 Express installed on my machine and it's working just fine. I also have the Management Studio Express CTP installed and working. I'm trying to connect to a database using a username and password (from ColdFusion Server which is working fine for external Oracle and Access databases, so that's not an issue), so I set up the server to allow mixed mode authentication. I can log in to the Management Studio using Windows authentication OR the username and password without any issues. I have TCP/IP enabled in the Configuration Manager and enabled. This seems like a ridiculous question, but I need to know the servername, port, username and password to connect to the database. I'm trying all combinations of things but nothing's working. If I put in as the server, 1433 as the port, and use the username and password that worked in Management Studio I get this: java.sql.SQLException: [Macromedia][SQLServer JDBC Driver]Error establishing socket. Connection refused: connect The root cause was that: java.sql.SQLException: [Macromedia][SQLServer JDBC Driver]Error establishing socket. Connection refused: connect If I use MACHINENAME\SQLEXPRESS I get this: java.sql.SQLException: [Macromedia][SQLServer

Cannot Install SQL Server 2005 Express due to MSXML 6 sp2

Got an XP Sp3 box - uninstalled SQL server 2008 Express r2.  Now I'm trying to install SQL server 2005 and am getting the ol' MSXML 6 SP2 error which is keeping SQL Server 2005 from installing.  Last time this happend there was the handy Installer Clean Up Utility but now you go to http://support.microsoft.com/kb/290301 and it's gone.  So what is the solution now?  Everything I've googled says to use the installer cleaner but it doesn't exist now so what now?

Can not connect to user instance of SQL Server 2008 Express with Advance Services in Visual Studio 2

I used SQL Server 2008 Express with Advanced Services (not SQL Server 2008 Express) in Visual Studio 2010 because it is the fast and easy way to developed and managed data-driven applications with powerful built-in reporting and full-text search functionality. I received Sql Server 2008 Service Pack 1 with Windows Update. It's ok if I connect to instance of SQL Server 2008 Express with Advance Services (with SP1) through SQL Server Management, but if I try to attach a database in Server Explorer (Visual Studio 2010), I get the following 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'm stuck at this point. Is there a fix or a workaround? I've already tried deleting the 'C:\Users\Administrtor\AppData\Local\Microsoft\Microsoft SQL Server Data\SQLEXPRESS' directory as mentioned in other posts, with no luck. The error.log at 'C:\Users\Administrator\AppData\Local\Microsoft\Microsoft SQL Server Data\SQLEXPRESS\error.log' has the following relevant entries: 2010-09-01 14:44:10.47 Server      Error: 17156, Severity: 16, State: 1. 2010-09-01 14:44:10.47 Server      initeventlog: Could not initiate the EventLog Service for the key '3677F6D3-17C7-4F', last error code is 2. 2010-09-01 14:44:10.47 Server &
